1.2.2
See Appendix I for Figures showing the breaks between Pipeline Act and Safety Codes
Act jurisdictions. Wellsite piping under the jurisdiction of the Oil & Gas Act and the
Pipeline Act shall be built to CSA Z662. Design engineer may designate other code
design if applicable to service. The drawings apply to Alberta but shall be used as a
guideline for other jurisdictions.
1.2.3
Where two or more codes, standards or regulations apply, the more stringent shall be
used in the design, fabrication and testing of pressure piping systems unless otherwise
approved in writing by the Company.
1.2.4
All piping elements such as pipe, flanges, fittings and other pressure containing
components and accessories shall be properly marked and registered in accordance with
the provisions of the applicable Provincial, Territorial and Federal Acts and regulations.
BASIS OF DESIGN
1.3
1.3.1
General
1.3.1.1
The design of pipeline systems shall provide for the most severe coincident
conditions of temperature, pressure and loading to co-exist under usual long term

operating conditions. These usual conditions include all manipulation and
control functions, such as throttling, blocking in and bypassing, etc., likely to be
used for operational control.
1.3.1.2
Usual operational conditions do not include more severe temporary conditions,
such as those incidental to start-up, shutdown or steam-out. Temporary
conditions govern as design conditions only when there is clear evidence that
they exceed time and severity limits in CSA Z662 Oil and Gas Pipeline Systems.
1.3.1.3
Design drawings shall clearly identify the break points between codes,
specifications and standards.
1.3.1.4
All pipelines shall be designed to allow for internal inspection tools and for
pigging with multidisk pigs.
1.3.1.5
The design of steam distribution pipelines shall meet the requirements of CSA
Z662 and be reviewed by the Alberta Boilers Safety Association (ABSA) prior to
the ERCB issuing of a license.
1.3.2
Emergency Shutdown Devices
1.3.2.1
1.3.3
Design Pressure
1.3.3.1
1.3.4
If an emergency shutdown device or any part of it fails on a pipeline in sour
service (a minimum of 10 moles H2S per kilometre or as specified), the
emergency shutdown devices shall fail in the closed (safe) position and remain
closed.
The design pressure of pipeline systems shall be greater than the maximum
expected operating pressure.
Design Temperature
1.3.4.1
In special cases of high pressure steam distribution systems then the design shall
be to saturation temperature at pressure, unless the process design is for dry
steam. In that case, a specific design shall be done and the line classes not used.
1.3.4.2
For pipeline systems containing fluids with boiling points below ambient
temperature at atmospheric pressure the effects of auto-refrigeration shall be
assessed and the proposed design minimum temperature approved by the
Company.
1.3.5
Other Loading and Dynamic Effects
1.3.5.1
The stress requirements in this Specification are specifically limited to design
conditions for operating pressure. Additional loadings other than the specified
loads are not addressed in this Specification; however, the designer shall
determine whether supplemental design criteria are necessary for such loadings
and whether additional strength or protection against damage modes or both
should be provided. Refer to Paragraph 4.2.4 in Z662-07 Oil and Gas Pipeline
Systems for additional loading examples.

1.3.6
Design of the pipeline system, including Wellsite piping shall be as required by CSA
Z662 Oil and Gas Pipeline Systems.
1.3.7
For all other pipelines, the stress level must not exceed 72% unless otherwise approved
by both the Provincial Jurisdiction and the Company. The Company must then submit a
non-routine application for the pipeline system.
LINE SIZING
1.4
1.4.1
Piping shall be sized for normal operating conditions in accordance with good
engineering practice and economical service. Line size determination (including
provisions for future increases in capacity) shall be made by CNRL Production and
Facilities Engineering.
1.4.2
The design of pipelines for steam service require special design considerations and prior
written approval from the Company.
MATERIAL SELECTION
1.5
1.5.1
The selection of material grade, thickness and any additional tests etc. shall be
determined by the design factors and service conditions. These factors and the additional
requirements are described in this specification.
1.5.2
All line pipe material shall meet requirements of CSA Z245.1, according to the grade
selected for the application. Line pipe material shall be ordered as CSA Z245.1
Grade 359 CAT II sour, unless otherwise determined by the pipeline coordinator
responsible.
1.5.3
The dimensional requirements of CSA Z245.1 shall apply, except that for nominal pipe
diameters of 406.4mm and over, the following additional requirements shall apply:
ƒ
The nominal outside diameter shall be within the tolerance specified in
CSA Z245.1 and in no case shall tolerance exceed –0.8mm or +3.2mm at
any location along the length of the pipe.
ƒ
The minus (-) wall thickness tolerance shall be within 5% of the
specified wall thickness.
ƒ
The ovality of the pipe at any point shall not exceed 2% of the outside
diameter or 12.7 mm (whichever is less).
ƒ
Root face dimensions shall, for a minimum average length and maximum
length shall be 7.6m, 21.5m, and 25.0m, respectively.
ƒ
The weld preparation tolerance shall be as per CSA Z245.1 Clause
10.8.1.2 except that the root face shall be within 1.6mm - 0.4mm.
COMMISSIONING
1.6
1.6.1
All newly constructed metallic pipelines are to receive an initial batch run of corrosion
inhibitor before the pipeline products are introduced unless this requirement is waived by
the Integrity Coordinator or Integrity Tech.

The specified materials in the line classes are acceptable to a design temperature of -40 C provided that
pipe runs do not exceed 50m in length. If pipe run lengths exceed 50m, materials meeting CSA Z662
category 2 requirements must be used if the design temperature is lower than -29C. Line pipe material
shall be ordered as CSA Z245.1 grade 359 Cat II, sour, unless otherwise determined by the Pipeline
Coordinator responsible.
Refer to Material Selection Section for material properties. Line pipe wall thicknesses are minimum
requirements. Applicable codes and regulatory standards may require additional thickness.
Dual certified flanges are acceptable for use.
Threaded joints on primary piping may be installed in sweet service, but should be minimized in sour
service. Allowable examples for primary sour service are pressure and temperature indicators. Other
uses shall be approved by the design engineer. Threaded joints are permitted in sour service on
secondary connections downstream of flanged connections where isolation from the main process is
possible.
Wall thickness to match pipe schedule.
To be used when mating to flanged nozzles.
These valves shall be used only for vent, drain, and instrument connections unless otherwise approved
by the Company.
Install in horizontal position with cover up.
Install in horizontal position with cover up or in vertical position with upward flow.
10.
The Line Pipe thicknesses listed were calculated using a design factor of 0.8, temperature factor 1.0, and
location factor 0.9 for class 1 locations only. Other location classes will require calculation to determine
required wall thickness.
11.
All welding shall meet the requirements of CSA Z662 for sour service.
12.
Flange pressure ratings in the table are based on CSA Z245.12 or ASME B16.5 which ever is more
stringent.
13.
Transition pieces between lengths of Line pipe and riser shall be fabricated with ASTM seamless pipe with
a minimum yield strength of 359 Mpa. The minimum length of Transition Pieces shall be 1000 mm. Both
ends of the Transition Piece shall be machined to a 37.5° bevel. The riser end of the Transition Piece shall
have a thickness as per the specification table. The Line pipe end of the Transition Piece shall be machined
to match the nominal thickness of the Line pipe. This machined area shall be either twice the diameter or
50 mm long at a minimum, whichever is greater.
14.
All risers are to be designed according to CSA Z662. Riser material can be dual certified to both CSA and
ASTM standards.
15.
Elbows, tees and other fittings for the above-ground part of the pipeline may be dual certified to ASTM and
CSA Z245.1.
16.
With the written approval of CNRL Pipeline Supervisor, the pipeline may be designated a “sweet” service
pipeline and the following changes may be granted:
•
The inspection scope may be reduced for sweet service to 15% RT; and
•
The use of fittings that have a minimum design metal temperatures of -29°C (-20°F), i.e. A105 carbon
steel, may be used.

Introduction and Line Classes - Pipelines
Thermal Pipeline Class Notes:
1. For pulsating (severe cycle) service radiography is required on 100% of the circumference of all
welds for new systems and piping modifications to existing systems (Less that 0.5 m3 / 18 cu.ft.). All
welds in pulsating service will be subject to post weld heat treatment unless otherwise approved by
the Owner.
2. For pulsating (severe cycle) service minimum 6000# forged steel socket weld fittings shall be used in
process piping.
3. For large, long life system requirements consider galvanized pipe and fittings using screwed end
connections throughout.
4. Use if large end is 1 ½” NPS or smaller.
5. Spectacle Blind.
6. Blind and Spacer.
7. Calculate pipe wall thickness.
8. Calculate pipe wall thickness. The pipe wall thickness used shall be a minimum of 9.6 mm (0.375 in.)
or the calculated thickness if larger than 9.6 mm (0.375in.).
9. Wall thickness to match pipe schedule.
10. Tubing is preferred over screwed pipe for NPS ¼” to ½” where possible and where support is not of
concern.
11. Use threaded tee and swage fittings (SE).
12. Flat faced flanges may be used where required for connection to flat faced flanges on equipment. In
such cases use 1.6 mm (1/16”) sheet gasket (Garlock or equal) over the full face.
13. Castings of material specification A352 Gr. LCB (Group 1.3 Material) have a lower maximum
working pressure than Group 1.1 Materials. Therefore, pressure piping systems containing valves
made from A352 Gr. LCB material (Group 1.3 Material) must have their piping class maximum
working pressure reduced to the level given in ASME B16.5 Table 2-1.3 governing Group 1.3
Material.
14. For sour salt water service, use Inconel spirotallic gaskets rather than 316SS material.
15. For SE piping, pipe schedule should be increased by one schedule or as necessary to meet minimum
thickness requirements as per Code. For NPS ½ to NPS ¾ threaded connections, use Sch XXS.
16. Where required by design, RTJ Flanges maybe used instead of RF Flanges.
17. Where it is not practical to butt weld ≤ 2” fittings socket welds are permitted on low pressure (up to
Class 600)

18. Use piston non-slam spring assist type check valve with soft seat in final discharge line of
reciprocating gas compressor service.
19. Use of flanges to be discussed with Operations Foreman before using in design of piping design or
before installation.
20. Use of check valves to be discussed with Area Operations Foreman before installing.
21. Welded connections preferred, if flanges are required, then use as specified.
22. For continued use below –20 ºC use A320 Gr.L7M studs and A194 Gr.7M nuts. Otherwise B7M
studs and 2HM nuts are acceptable.
23. For high point vent use: ¾” NPT Threadolet c/w plug.
24. Swages fabricated to MSS-SP-95, end preparation to match joining fittings.
25. Wall Thickness should correspond to the joining pipe wall thickness or schedule. The ends shall be
taper-bored to suit matching pipe wall if fitting thickness exceeds pipe wall by more than 1.6 mm.
26. Used only when approved by Mechanical Engineering & CNRL Operations.
27. Mainly used for drain and instrument root valve connection.
28. Dual certified flanges (ASME B16.5 and CSA Z245.12) are acceptable for use. CSA Z245.12 is the
minimum acceptable certification.
29. All materials must meet the requirements of CSA Z662-07 and be listed on Table 5.3. All ASME
material must be certified for use in pipelines by CSA.
30. Material to be used for vent and drain connections only.
31. Material Grade and Category to match (or exceed) the mating pipe grade and category.
32. RTJ flanges are acceptable for the hot air warm up tees

5.3.1
Accumulation – the pressure increase over the Maximum Allowable Working Pressure
(MAWP) of a vessel during discharge through the pressure relief valve expressed as a
percent of MAWP. The ASME Boiler and Pressure Vessel Code establish the maximum
allowable accumulations for operating contingencies and for fire contingencies.
5.3.2
Back Pressure – a general term for the pressure existing at the outlet of a pressure relief
valve. When the pressure relief valve is closed, it is equal to the Superimposed Back
Pressure. When the pressure relief valve is open, it is equal to the sum of the
Superimposed Back Pressure and the Built-Up Back Pressure.
5.3.3
Built-Up Back Pressure – the increase in back pressure at the pressure relief valve outlet
that develops as the result of flow after the pressure relief valve opens.

Flare System Design
5.3.4
Design Pressure – the gauge pressure used in the design of the vessel. Also see
Maximum Allowable Working Pressure.
5.3.5
Maximum Allowable Working Pressure – the maximum gauge pressure permissible at the
top of a completed vessel in its operating position for a designated temperature. The
MAWP is stated on the vessel ASME code stamp and is the basis for the pressure setting
of the pressure relief valves protecting the vessel. The MAWP is generally equal to, or
slightly more than, the Design Pressure.
5.3.6
Maximum Superimposed Back Pressure – the maximum value of the Superimposed Back
Pressure on an unopened pressure relief valve at the time the valve is required to operate.
In flare systems, it is a result of flow from other pressure relief valves and/or from other
simultaneous flaring.
5.3.7
Overpressure – the pressure increase of the vessel over the Set Pressure of the pressure
relief valve. It is the same as Accumulation when the pressure relief valve is set at the
vessel MAWP.
5.3.8
Relief Valve – an automatic pressure-relieving device actuated by the static pressure
upstream of the valve, which opens in proportion to the increase in pressure over the
opening pressure. A relief valve is used primarily for liquid service.
5.3.9
Rupture Disk – a non-re-closing pressure relief device actuated by inlet static pressure
and designed to function by the bursting of a pressure-containing disk.
5.3.10 Safety Relief Valve – a pressure relief valve characterized by rapid opening or “pop”
action or by opening in proportion to the increase in pressure over the opening pressure,
depending on application.
5.3.11 Safety Valve – an automatic pressure-relieving device actuated by the static pressure
upstream of the valve and characterized by rapid full opening or “pop” action. It is used
for gas or vapor service.
5.3.12 Set Pressure – the inlet gauge pressure at which the pressure relief valve is set to open
under service conditions. Set Pressure is the single valve of the intended Opening
Pressure and as such is independent of Superimposed Back Pressure.
5.3.13 Superimposed Back Pressure – the static pressure existing at the outlet of an unopened
pressure relief valve at the time the valve is required to operate. It is the result of
pressure in the discharge system from other sources and may be constant or variable.
PRESSURE RELIEF VALVES

Flare Header Sizing and Design
5.8.3.1
Flares, headers, subheaders, and pressure relief valve discharge laterals shall be
sized so that they collectively meet the maximum Back Pressure limits noted in
Section 5.8.2.3 for each relief case for each pressure relief valve discharging to
flare.
5.8.3.2
Flare system pressure drop calculations are made in a stepwise manner starting at
the flare tip by calculating the pressure drop for each flare system piping segment
of constant diameter and constant flare load.
5.8.3.3
The primary calculation shall be made using the relief case that has the highest
total flare load. This will set the size requirement for the flare, the flare knockout
drum, and the common flare header. The calculation shall determine the Back
Pressure at each pressure relief valve and verify that the Back Pressure limits are
not exceeded. Each pressure relief discharge lateral shall be sized in a similar
manner. The full open pressure relief valve capacity shall be used.
5.8.3.4
All laterals from individual relieving devices should drain to the flare header. All
flare piping shall be sloped a minimum of ¼ inch in 10 ft (21 mm in 10 m).
5.8.3.5
All flare system piping shall be designed and tested per B31.3. Isolation of the
piping shall be provided with flanges. Block valves for testing purposes shall be
avoided.
5.8.4
Vapor Depressuring
5.8.4.1
An emergency vapour depressuring system can be employed to prevent metal
temperatures from reaching a level at which stress rupture could occur during a
fire.

5.8.4.2
The recommended sizing criteria is to reduce the equipment pressure from initial
conditions to a level equivalent to 50% of the vessels design gauge pressure or
100 psig, whichever is lower, within approximately 15 minutes.
5.8.4.3
The flow capacity of a vapour depressuring valve shall be calculated assuming
100% open. The back pressure in the flare header shall be calculated using the
maximum vapour depressuring rate combined with any other relief valve that
may discharge simultaneously.
5.8.5
Flare Knock-out Drums
5.8.5.1
5.8.6
A minimum design pressure of 50 psig is required for flare knock-out drums.
The vessel should be designed according to the specifications of the ASME code,
although a code stamp is not required if the vessel pressure can never exceed
15 psig based on the back pressure calculations. This is also subject to local
regulations and requirements. A vessel with a design pressure of 50 psig should
not rupture if an explosion occurs.
Flare Stack
5.8.6.1
Although flare stack diameters are sized based on a velocity criteria, the pressure
drop should be checked and the back pressure on the flare knockout drum
calculated. A velocity up to 0.5 Mach for peak, short-term, infrequent flow is
recommended and 0.2 Mach for normal, frequent conditions or continuous
flaring.
5.8.6.2
The flare stack height is based on the radiant heat intensity generated by the
flame. A radiation level of 1500 Btu/hr ft2 should not be exceeded at the base of
the stack.
5.8.6.3
A continuous pilot with a means of remote ignition is recommended for all flares
to ensure ignition of flare gases.
5.8.7
Vent Stack
5.8.8
Vent stacks or the tips of vent stacks are generally sized for an exit velocity of at least
500 ft/s at the maximum relief rate.
5.8.9
Flashback Prevention
5.8.9.1
The continuous use of purge gas is required for all continuous flare stack
installations. The purge gas flow shall be ensured at all times by controlling the
flow and measurement with the provision of a low flow switch and alarm.
5.8.9.2
Flame arrestors shall not be used for continuous flare stack installations. Flame
arrestors are only permitted on non-continuous vent stacks at remote locations
where it is not possible to provide purge gas.

DEFINITION OF SOUR SERVICE
8.3
8.3.1
For carbon and low alloy steels, sour service is defined as when the hydrogen sulfide
(H2S) exceeds 0.30 kPa (0.05psi). Partial pressure is calculated as follows:
8.3.2
Mole fraction H2S (mole % H2S / 100) x total system pressure = H2S partial pressure
8.3.3

Sour Service Piping
8.3.3.1
The mole fraction equivalent to 2.5% H2S is 0.025. If the maximum system
pressure is 1000 kPa, then the H2S partial pressure is 0.025 x 1000 = 25 kPa.
8.3.3.2
The mole fraction equivalent to 50 ppm is 50 x 10-6 or 0.00050. If the maximum
pressure is 1000 kPa, then the H2S partial pressure is:
0.00050 x 1000 = 0.05 kPa.

SUMMARY .................................................................................. 84
10.1
SCOPE
10.1.1 A Bake Out is required for all tie-ins to existing sour systems. The bake out procedure
below is limited to P1 low carbon (<0.45 CE) steel materials only.
10.1.2 Comment: This applies to CSA Grade 290, Grade 359, and Grade 414 ASTM A-106-B,
A-234-WPB, A-105, A-333 Grade 6, A-420 WPL6, A-350 LF2 and other low carbon P1
steels. For medium or high carbon steels, low alloy & alloy steels consult the Integrity
Group.
10.1.3 Bake outs can be performed by two methods; stress relievers (induction coil) and liquid
propane torch. Stress relievers are the preferred method and should be used whenever
possible.
10.1.4 Where the consequence and risk of a failure is high (i.e. safety of in-plant personnel) the
use of stress relievers are strongly recommended.
10.2
BAKE OUT PROCEDURE
10.2.1 Clean metal to white, 150 mm (6") back from area to be welded, on each side of weld.
10.2.2 Conduct MPI inspection of the cleaned area to ensure there are no surface cracks.
10.2.3 Clean and degrease surface.
10.2.4 Conduct bake out using an induction coil or a propane torch. The bake out temperature
shall be measured on the bottom of the line using a Tempil stick, pyrometer or
thermocouple.
10.2.5 Heat up the pipe slowly from ambient to 450 C (842 F). This heating cycle should take at
least one (1) hour to heat up the area. The bake out temperature should be maintained for
a minimum distance of 75 mm (3”) back from the weld bevel. The bake out temperature

Hydrogen Degassing
Note: requires one hour to ensure hydrogen migrates out of the weld area to
prevent delayed hydrogen cracking.
10.2.7 Cool down to preheat temperature. Insulation is recommended for a controlled cooling
rate. The insulation blanket should be wrapped completely around the pipe and the
temperature should be measured on the bottom of the pipe. This cooling cycle should
take at least one (1) hour. Don't go below the welding preheat temperature and be
prepared to weld as soon the weld preheat temperature is reached.
10.2.8 Comment: Hydrogen will have a tendency to migrate back into the area if the weld area
is cooled below the preheat temperature.
10.2.9 MPI (using black on white contrast) 12 hours after completion of welding.
10.3
SUMMARY
10.3.1 The purpose of a bake out is to reduce the hydrogen that accumulates in steel in sour
service. This hydrogen can result in hydrogen cold cracking of the weld. This type of
cracking may occur up to 48 hours after the weld has been completed. The temperature
must not exceed 650 C to prevent heating into the lower critical region. Above 723 C the
metallurgical properties of the steel will be changed resulting in changes to the
mechanical properties.

13.9.3 Procedure
13.9.3.1
Preheat heating tool to 260o C and check heating tool temperature with Tempil
sticks. Test three sides of the tool. This is to be done each time the heating tool
is plugged in and four times a day during continuous use.
Record tool temperature on all fusions.
13.9.3.2
13.9.3.3
The immediate area of the fusions may have to be tarped off to reduce the
cooling effects of wind.
13.9.3.4
Alignment of the pipe is more difficult because the plastic is stiffer and
additional mechanical stabilizers may be needed.
13.9.3.5
Allow additional time. At increasingly cold temperatures, the plastic will take
longer to heat due to the low temperature of the pipe. Tarping becomes more
critical to reduce the likelihood of having cold plastic close to the fusion
preventing a proper bond.
13.9.3.6
Heating cycles begin once the bead has fully formed around the entire
circumference of the pipe.
13.9.3.7
Pipe clamps may have to be shimmed to prevent pipe slippage as traction is more
difficult on cold polyethylene.
13.9.4 Inspection:
13.9.4.1
Melt bead must be completely rolled back on both sides and touching the pipe
wall.
13.9.4.2
Melt bead must be of uniform height and width.
13.9.4.3
Pipe fitting or valve ends must be properly aligned.
Caution: Only upon the attainment of all above conditions
shall the join pass inspection. The Inspector should also perform a
spot check (quality control) of the crew by having them cut out a
(random) specimen for testing. The cuts should be 10 cm on either
side of the completed fusion, then a 2 to 3 cm strip can be cut
lengthwise from the coupon. Inspect the internal and external beads
for proper shape and size according to Melt Bead Size Chart (table
13.11.7 below). Freeze the sample and then bend back and forth to
failure. If it fails on the fusion face the crew needs to adjust their
procedure or equipment.
Note: Due to the characteristics of polyethylene fusions, a
successful pressure test does not necessarily mean that all of the
fusions are proper and will hold in the long term.

GENERIC BUTT FUSION PROCEDURE
13.10.1 Clean the inside and outside of the pipe to be joined by wiping with a clean lint-free
cloth. Remove all foreign matter before clamping the components in the machine.
13.10.2 The pipe ends must be faced to establish clean, parallel mating surfaces. Most, if not all,
equipment manufacturers have incorporated the rotating planer block design in their
facers to accomplish this goal. Facing is continued until a minimal distance exists
between the fixed and movable jaws of the machine and the facer is locked firmly and
squarely between the jaw bushings. This operation provides for a perfectly square face,
perpendicular to the pipe centerline on each pipe end and with no detectable gap.
13.10.3 Remove any pipe chips from the facing operation and any foreign matter with a clean,
untreated, lint-free cotton cloth. The pipe profiles must be rounded and aligned with each
other to minimize mismatch (high-low) of the pipe walls. This can be accomplished by
adjusting clamping jaws until the outside diameters of the pipe ends match. The jaws
must not be loosened or the pipe may slip during fusion. Re-face the pipe ends and
remove any chips from re-facing operation with a clean, untreated, lint-free cotton cloth.
13.10.4 The surface temperatures of the pipe must be in the temperature range of 204-232°C.
Heating tools are used that simultaneously heat both pipe ends are used to accomplish
this operation. These heating tools are normally furnished with thermometers to measure
internal heater temperature so the operator can monitor the temperature before each joint
is made. However, the thermometer can be used only as a general indicator because there
is some heat loss from internal to external surfaces, depending on factors such as ambient
temperatures and wind conditions. A pyrometer, Templlstiks or other surface
temperature-measuring device should be used periodically to insure proper temperature
of the heating tool face.
13.10.5 Additionally, heating tools are usually equipped with suspension and alignment guides
that center them on the pipe ends. The heater faces that come into contact with the pipe
should be clean, oil-free and coated with a nonstick coating as recommended by the
manufacturer to prevent molten plastic from sticking to the surfaces. Remaining molten
plastic can interfere with fusion quality and must be removed according to the tool
manufacturer’s instructions.
13.10.6 To ensure that full and proper contact is made between the pipe ends and the heater, the
initial contact should be under moderate pressure. After holding the pressure very briefly,
it should be released without breaking contact. On larger pipe sizes, initial pressure may
be maintained until a slight melt is observed around the circumference of the pipe before
releasing pressure. Continue to hold the components in contact with the heating element,
without force, while a bead of molten polyethylene develops between the heater and the
pipe ends. Approximate melt bead sizes for various pipe sizes are:
13.10.7 Pipe size
1 ¼” and smaller (40mm and smaller)
Above 1 ¼” through 3” (40mm-90mm)
Above 3” through 8” (90mm-225mm)
Melt bead size
1/32” – 1/16” (1-2mm)
About 1/16” (2mm)

Caution - If a concave melt surface is observed, unacceptable pressure
during heating has occurred and the joint will be low quality. Do not continue.
Allow the component ends to cool completely, and restart at the beginning.
13.10.8 When the proper bead size is formed against the heater surfaces, remove the heater
Note-On Holding Pressure
Hold the molten joint immobile under 60-90 psi interfacial fusion pressure until
cooled adequately to develop strength. Allowing proper times under pressure for
cooling prior to removal from the clamps of the machine is important in
achieving joint integrity. The fusion force should be held between the pipe ends
for approximately 30-90 seconds per inch of pipe diameter or until the surface of
the bead is cool to the touch. Avoid pulling, installation or rough handling for an
additional 30 minutes.
Fusion force is determined by multiplying the interfacial pressure 414-620 KPa
(60-90 psi) by the pipe area. For manually operated fusion machines, a torque
wrench can be used to accurately apply the proper force. For hydraulically
operated fusion machines, the fusion force can be divided by the total effective
piston area of the carriage cylinders to give a hydraulic gauge reading. The
gauge reading is theoretical; internal and external drags are added to this figure
to obtain the actual fusion pressure required by the machine. The hydraulic
gauge reading and the interfacial pressure are not the same value.
13.11
13.10.8.1.1
After the heater tool is removed, quickly inspect the pipe ends.
Immediately bring the molten pipe ends together with enough force to
form a double rollback bead against the mating pipe wall.
13.10.8.1.2
Avoid pulling or rough handling of the Joined pipe for approximately 30
minutes.
INSPECTION
13.11.1 Melt bead must be completely rolled back on both sides and touching the pipe wall.
13.11.1.1
Melt bead must be of uniform height and width
13.11.1.2
Pipe fitting or valve ends must be properly aligned.

16.1
PROCEDURE FOR ASME B31.3 CARBON STEEL PRESSURE PIPING
AND CSA Z662 “TIE-IN” WELDS NOT SUBJECTED TO
HYDROSTATIC TESTING
16.1.1 Scope
The following outlines the requirements for evaluating and doing tie-ins to
pressure piping systems relative to Hydro Testing or using the Closure Weld
definition of ASME B31.3, clause 345.2.3 (c) and welds that fall under the
definition of “tie-in” welds as per clause 8.14 of CSA Z662.
16.1.2 This specification applies ONLY in cases where an ENTIRE SYSTEM cannot be
hydrostatically tested. A specific set of requirements must be developed and approved
for each SYSTEM that cannot be hydrostatically tested.
16.1.3 This Guideline is to be used only for closure welds or tie-in welds, and only when
hydrostatic testing is not practical. It is NOT intended as an avenue to circumvent the
requirement for a hydrostatic test.
16.1.4 Prior approval for waiver of hydrotest must be obtained from the Facilities engineer or
the Chief Inspector.
16.1.5 Unless specifically noted, these guidelines apply to both B31.3 and Z662.
16.2
PROCEDURE TO BE USED FOR BUTT WELDED PIPE
16.2.1 The complete “tie-in” weld (ASME B31.3) from preparation to sign off must be
controlled by the individual who is nominated as the Owners Inspector according to
ASME B31.3. An Inspection Travel Sheet (attached to this specification) must be used to
document inspections that comply with ASME B31.3, Para 344.7. The elements of InProcess Examination are:
a.
Verification of fit-up
b.
Preheat temperature

c.
Ensuring the use of properly conditioned electrodes (new sealed package and
heated)
d.
MPI of the root (or hot pass if the base material is more than 3/8” thick)
e.
MPI or LPI and full RT of the completed weld.
16.2.2 The complete weld (CSA Z662) must be controlled in a similar manner as described
above. The travel sheet shall be used for Z662 welds in the same manner as for B31.3
welds.
16.2.3 The welding procedure for B31.3 welds must be approved by the Company. It must be
qualified to cover the material, wall thickness, and testing required for the materials
involved. The WPS should use low hydrogen electrodes. Use of E-7010 cellulose
electrodes is allowed for the root pass only. A minimum of 150° F (66° C) ± 25°F (±14
°C) preheat is to be used, or as stipulated by the WPS. The preheat is to be maintained
throughout the welding process and monitored by a minimum of two temperature
indicating crayons (one at each end of the preheat range) or equivalent.
16.2.4 The welding procedure for Z662 welds shall be tested and certified as per clause 7.2 of
Z662 for the pipe material in question. ASME B31.3 qualified welding procedures are
acceptable provided they meet the requirements as stipulated in Z662 7.2.5.
16.2.5 Piping joints shall be prepared as per the welding procedure specification. Bevelled edges
must be visually inspected to ensure proper fit-up.
16.2.6 After completion of the root pass, smooth out the root area by grinding and carry out dry
powder MPI to ensure there are no crack like defects. Maintain minimum preheats during
inspection.
16.2.7 Complete welding according to the weld procedure and wrap the completed weld in an
insulating blanket and allow the weld to cool to ambient temperature as slow as possible.
16.2.8 Final MPI or LPI and 100% RT to be done not less than 1 hour after cooling.
16.2.9 If the joint is to be PWHT, the NDE must be done following the PWHT and may be done
as soon as it cools to ambient temperature. It is recommended that NDE also be done
prior to PWHT to ensure that the welds are acceptable prior to heating. The PWHT shall
be done as specified in the WPS, and the applicable code.
16.2.10 The new piping spools that are being “tied-in” must be previously hydro tested and all
documentation completed and signed off by the appropriate authorities.
16.3
PROCEDURE FOR SOCKET WELDED PIPE
All of the above apply as appropriate except:
16.3.1 Preheat the joint to minimum 150° F (66° C) ± 25°F (±14 °C) or as specified in WPS and
maintain for the duration of the welding process.
16.3.2 Perform MPI at least 1 hour after the weld has cooled to ambient temperature. Wet
contrast method is preferred.

1. Initially oil emulsion pipelines need to be pigged for wax and paraffin control. Heavy oil
pipelines need to be pigged for solids and corrosion control. As the water cut reaches the 20 –
40% level, pipelines may have to be pigged for corrosion control. Batch inhibition programs are

Pigging Facilities
often a key part of the corrosion control program. Oil well flow lines should have a pigging valve
as a minimum. Group flow lines should have full scale pigging facilities.
2. Wet, sweet gas lines with low C02 partial pressures (below 50 kPa or 7 PSI C02 partial pressure)
may need pigging facilities for:
• Hydrate control
• Production pigging to remove fluids (water and/or condensate) and reduce line pressure.
• Remove sand, scale or other solids
• To minimize corrosion
3 No pigging facilities are required for fuel gas lines.
4 Salt or produced water lines should be internally coated and/or lined and should not require
pigging.
5 If fresh water lines are internally coated and/or lined, they should not require pigging. If fresh
water lines are internally bare, they should be designed with pigging facilities so that they can be
pigged for removal of deposits.
6 Full scale pigging facilities are recommended for wet, sour gas pipelines because a batch
inhibition program is often part of the corrosion mitigation program. It is much easier to keep a
batch slug together with full scale pigging facilities.
7 Full scale pigging facilities are recommended for wet, sweet gas pipelines with high CO2, partial
pressures (greater than 50 kPa or 7 PSI C02 partial pressure) because a batch inhibition program is
often part of the corrosion mitigation program. Corrosion at the 12 o’clock position is a concern
on sweet gas pipelines and a batch treatment is necessary for the corrosion inhibitor to contact the
top part of the pipeline. It is much easier to keep a batch slug together with full scale pigging
facilities.
8 “Clean” oil or condensate (100% oil) should have full scale pigging facilities to allow pigging to
control wax and/or paraffin and also for self-contained “smart” pigs.
9 Sweet, dehydrated natural gas lines, HVP and LVP pipelines should have full scale pigging
facilities to be able to pig following process upsets. They also should have full scale pigging
facilities to allow self-contained “smart” pigs.
10 Medium density polyethylene pigs should be used in high density polyethylene (HDPE) lined
pipelines. Disc type pigs may get caught on, or tear, the internal polyethylene weld.
Caution – Reuse of pig traps is allowed within CNRL as long as there is traceability to
the pressure and service. Pig traps that are removed from existing systems shall be tagged
with the pipeline licence and line number so that we maintain traceability to pressure and
service.

SCOPE
27.1.1 The ERCB and other regulatory bodies require an application for a conversion of a sweet
registered pipeline to transport sour natural gas. Sour natural gas is considered sour for
materials purposes, by a partial pressure criteria.
27.1.1.1
For gas pipelines the line is sour if the partial pressure of the H2S is 0.30 kPa or
greater as determined by: (H2S (moles/kilomole) X MOP (kPa)) divided by 1000
= partial pressure. See section 8.0 for details.
27.1.1.2
For oil effluent pipelines the line is sour if the partial pressure of the H2S is 0.30
kPa or greater as determined by same formula: See ERCB Directive 56.
27.1.2 An application is also required when a natural gas line containing H2S is licensed for less
than 10 mol/km of H2S, and exceeds or intends to exceed that limit.
27.2
GENERAL
When a sweet to sour pipeline conversion is considered, the following steps must be
taken:
27.2.1 Coordinated through the appropriate CNRL Integrity Coordinator in Calgary.
27.2.2 A non-routine application completed in accordance with ERCB Directive 56 or other
regulator as required. This should include the applicable sections of the ERCB
“Checklist for Minimum Technical Requirements for Pipeline Applications”.
27.2.3 The Integrity Coordinator must prepare an application which is supported by an
engineering assessment, demonstrating compliance with the sour service requirements of
CSA Z662.
27.2.4 ERCB or equivalent approval obtained.
27.2.5 CNRL safety group informed so amendments to the Emergency Response Plan (ERP)
can be assessed.

Third Party Tie-Ins
28.3.2 On HIGH OR MEDUIM RISK tie-ins (sour or other corrosive fluids, population
concerns, water crossings etc., as determined by the line with the higher risk):
28.3.2.1
Tie-in to the closest existing above ground piping if practical, or, tie-in below
ground with standard vertical tee or hot tap tee and come above ground.
28.3.2.2
Install an above ground isolation valve if not existing and;
28.3.2.3
Install an above ground check valve if not existing and;.
28.3.2.4
Install above ground pressure protection (regulators, relief valves etc.), ESD’s or
other safety equipment as required by current CSA Z662 and/or provincial
regulations, if not existing.
28.3.3 On LOW RISK tie-ins (sweet shallow gas, no population concerns etc. as determined by
the line with the higher risk)
28.3.3.1
Tie-in to the closest existing above ground piping if practical using the
requirements of 28.3.2, or;
28.3.3.1.1
Option #1 (possible only if no pressure protection required): Tie-in
below ground with sweep tee with buried full-port isolation valve.
28.3.3.1.2
Option #2 (possible only if no pressure protection required): Tie-in
below ground with standard horizontal tee or hot tap tee c/w isolation
valve on top of the tee.
28.3.4 Canadian Natural “Ground Disturbance Permits” must be completed and proper
backfilling done (see section 29.0 & 31).
Caution – Canadian Natural recognizes the risks of burying valves and
flanges. However, with the proper application of water proofing coatings such
as Densotape, corrosion and valve functionality can be maintained. Inspections
should be rigorous to ensure that due care and attention was taken in selecting
and applying the coatings.
Note: Hot tap procedure must be approved by Pipeline Integrity Group.
See “Hot Tap” section 11.0 in this manual.

SCOPE ...................................................................................... 147
PROCEDURE............................................................................. 147
SCOPE
29.1
29.1.1 Backfilling and ditching shall be done in accordance to CSA Z662 and applicable
provincial pipeline acts and regulations. CNRL Ground Disturbance form must be filled
out.
29.1.2 In Alberta the ERCB must be notified (electronically) 24 hours before the start of
construction.
29.1.3 In BC, the OGC must be notified by fax, 48 hours in advance of the start of construction.
PROCEDURE
29.2
29.2.1
The contractor must advise landowners no less than 48 hours prior to moving excavation
equipment onto the ROW. It is important to ensure the ROW is properly surveyed and
marked and to maintain these markings for the duration of the work.
29.2.2 Clearing, grading and other preparatory work must be done only as far as is required for
the work, and restored to a condition afterwards that will adequately control adverse
results of ground disturbance.
29.2.3 In permafrost areas the thermal regime should not be disturbed, or disturbed as little as
possible.
29.2.4 Ditching is to be done to a depth that will accommodate a suitable bed, and sufficient
cover.
29.2.4.1
CNRL construction practice is to maintain minimum cover of 152 cm (5 feet) for
steel lines.
29.2.4.2
In unusual circumstances where 152 cm cannot be attained, the minimum cover
under Z662 is 60 cm. In Alberta, the ERCB impose a stricter limit on minimum
cover requirements and requires 80 cm as a minimum.
29.2.5 The ditch shall have an even bottom surface so the pipe will bear evenly when lowered,
without rock, frozen lumps of soil etc.
29.2.6 The ditch shall be of adequate profile to fit the pipeline without undue force on the pipe.

Ditching and Backfilling
In situations where the pipeline, especially bended portions, do not match the
ditch profile and cause pressure on the pipe, the ditch must be modified to better
accommodate the pipe.
29.2.7 Backfilling is to be done in manner that will not damage the pipe coating or the pipe
itself. If the pipe external coating is damaged during lowering-in or backfilling, it must be
repaired.
29.2.8 Backfilling shall be done as soon as possible after the pipe has been lowered into the
ditch. Backfill shall be done to ground level, then tamped down and levelled again.
29.2.9 All line crossings shall be underneath existing structures, and a minimum distance of
600mm must be maintained between the line being laid and other underground structures.
29.2.10 Polyethylene and fiberglass pipelines shall be laid on undisturbed or well-compacted
soil or otherwise continuously supported, and shall not be supported by blocking.
29.2.10.1
Where ledge rock, hardpan, or boulders are encountered, the trench bottom shall
be padded, using sand or compact fine-grained soils that extends a minimum of
150 mm from the pipe wall in all directions. See Section 19 for rock guard
information.
29.2.10.2
Polyethylene and fibreglass pipelines shall be installed ensuring that shear and
tensile stresses resulting from installation, backfill, thermal contractions and
external loading are within acceptable levels.
29.2.10.3
The depth of cover shall be as for steel pipelines.

REQUEST FOR DEVIATION
34.3.1 When, in a specific application, it is impossible or impractical to follow an established
Company specification, the person responsible for the design and/or construction and/or
repair has to prepare and submit a request for a deviation from specification.
34.3.2 For that purpose, the attached form (See Appendix I) may be used.
34.3.3 The justification for deviation must address the reason for requiring the deviation. If the
reason for deviation is commercial/financial, the application must be countersigned by
the area superintendent (for requests originating in the field) or the facilities manager (for
requests originating in the facility group).
34.3.4 If the deviation involves using material of lower schedule or rating than that specified,
the application must be accompanied by calculations showing the requested change will
still comply to the applicable code.
34.3.5 As part of the justification process, a risk analysis must be conducted on the proposed
change. This analysis must review safety, operations and costs advantages and offsets. At
this time, follow up actions will be identified and the persons responsible tasked with
these follow up action items.
34.3.6 The notes from the risk analysis and the list of follow up actions are to be included on the
deviation form in the appropriate locations.
34.3.7 The attached form is to be completed and submitted for approval.
34.4
APPROVAL
34.4.1 The request for deviation must be submitted to the Facilities Group for approval. A
request for a deviation will be granted for a particular project or task only.
34.4.2 The Facilities Engineer/Technologist responsible for the area or project will review the
application in terms of design suitability. The manner in which the deviation will
influence operations and/or safety and/or ease of fabrication have to be considered,
amongst others. The Facilities Engineer/Technologist must verify compliance to the
applicable Code.
34.4.3 If the Facilities Engineer/Technologist is the originator of the application for deviation, a
peer or the Facilities Manager should review the application for approval.
34.4.4 Once approved by the Facilities Engineer/Technologist, the application is routed to the
Chief Inspector for review in relation to the applicable jurisdictional regulations and
Code requirements.
34.4.5 When approved by the Facilities Engineer, the application for deviation may be
implemented in the field or shop as appropriate.
34.4.6 At this point, the Facilities Engineer will assign a number to the deviation for record
keeping purposes.
