Design and Rating of Equipment for Use at Elevated Temperatures
G.1 General
In accordance with 4.3.2, the design of equipment for temperatures above 1 21 °C (250 °F) shall include the
effects of temperature on material strength.
NOTE 1 This annex provides two methods that may be used for the design and rating of equipment for use at elevated
temperatures. The first is to de-rate the working pressure of the equipment at the elevated temperature to a pressure
less than the room-temperature full-rated working pressure of the equipment. The second is to design the equipment for
full-rated working pressure at the elevated temperature.
NOTE 2 Data on the performance of flanged end connectors, as specified in this specification, at elevated
temperatures are available in API 6AF1 .
Caution —Annex G is not intended as a material selection guide for high-temperature use. Some
alloys are embrittled after repeated or prolonged exposure to elevated temperatures. Care should be
used in selection of alloys for these ratings. If plated or coated materials are used at temperatures
greater than 1 80 °C (350 °F), the cracking potential can be increased.

G.4 Marking of De-rated Equipment
In addition to the marking requirements of Section 1 2, equipment supplied for temperature ratings above
250° F (1 21 ° C) that is de-rated shall have the de-rated working pressure for the applicable maximum
temperature marked on the equipment.
G.5 Design of Equipment for Use at Elevated Temperature
G.5.1 General
It has been demonstrated that some flanges specified in this specification are capable of being used at full
working pressure at elevated temperatures. In addition, some OECs are capable of being used at full-rated
working pressure at elevated temperature. One purpose of this annex is to provide rules for the design of
equipment for operation at full-rated working pressure at elevated temperature.
A second purpose of this annex is to provide rules for the design of de-rated equipment for use at elevated
temperatures.
G.5.2 Procedure
G.5.2.1 General
De-rated equipment may be designed in accordance with the rules of API 6X, extended to include hightemperature cases as follows.
There is no change to the rules of design for hydrostatic test conditions, since shell testing is carried out at a
temperature between 4 °C and 50 °C (between 40 °F and 1 20 °F).
For the operating conditions that include rated working pressure and loading at rated temperature, an Sm
value may be used equal to two-thirds of a de-rated material yield strength, Se, at rated temperature. Derated yield strength may be determined by one of the methods given in G.5.2.2 or G.5.2.3.
Elevated-temperature tensile strength shall be determined in the same manner as the elevated-temperature
yield strength.
G.5.2.2 Testing at Elevated Temperature
G.5.2.2.1 QTC Testing
Se at temperature shall be the minimum measured yield strength of the material tested at the rated
temperature of the equipment. The room-temperature mechanical properties of the material shall equal or
exceed the minimum requirements for the strength class of Table 8. The elevated-temperature tensile test(s)
shall be performed on specimens removed from the required location within the same QTC used for roomtemperature tensile testing. At least one elevated-temperature tensile test shall be performed at the rated
temperature of the equipment, using the methods of ASTM E21 or equivalent methods.
If the elevated-temperature yield strength, E ty, meets or exceeds the minimum specified room-temperature
yield strength, Smy, of Table 8, then Smy may be used as Se for the design. If the E ty is less than the Smy, then
a value no greater than E ty shall be used as Se for the design.
If the elevated-temperature test fails to meet the above requirements on the first attempt, two additional
tensile tests may be performed to qualify the material. The results of each of these tests shall satisfy the
required yield strength.
350
API S PECIFICATION 6A
G.5.2.2.2 Material Grade Qualification Testing
Se at temperature shall be minimum yield strength of the material strength class of Table 8, reduced by the
amount of de-rating of yield strength at the elevated temperature compared to the measured yield strength a
temperature between 4 °C and 50 °C (between 40 °F and 1 20 °F).
Qualification testing shall be performed on a minimum of five heats of the material grade (same UNS alloy
number or individual material composition and same heat-treat condition) for a particular strength class at
elevated temperature and at room temperature. In addition, the room -temperature and elevated-temperature
tensile specimens shall be obtained from the required location within the same QTC for a given heat. The
yield strength values, E ty and R ty, shall each be averaged for use in determining the amount of yield derating at a particular temperature.
The yield reduction ratio at temperature, Yr, shall be calculated as given in Equation (G.1 ):
Yr 
E ty
R ty
(G.1 )
where
R ty is the room-temperature yield strength (measured, 5 heats minimum);
E ty is the elevated-temperature yield strength (measured, 5 heats minimum).
The elevated-temperature yield strength, Se, is then calculated as given in Equation (G.2):
Se  Yr Sy
(G.2)
where
Sy is the minimum specified room-temperature yield strength for the material.
The elevated-temperature tensile data along with the room-temperature data for the material grade shall be
contained in a material qualification file for each material grade, and it is not necessary that this test be
performed on a heat lot basis.

Annex H
(informative)
Recommended Assembly of Closure Bolting
H.1 Lubrication
H.1 .1 Gasket Lubrication
Ring gaskets installed in 6B or 6BX flanged and studded connectors should be lightly lubricated prior to
assembly. Appropriate lubricants include mineral-base oil (20 W or higher), synthetic motor oil (5W or higher)
or a general-purpose grease suitable for high-pressure metal-to-metal application. Greases or thread
compounds with metallic additives shall not be used. Lubricant, if applied, shall be applied as a thin film,
never in sufficient amount to have any possibility of filling the grooves.
This is recommended to avoid galling of the gasket and/or ring groove mating seal surfaces and is
particularly important for stainless steel or CRA ring grooves. The connections are designed to achieve a
mechanical preload between the gasket OD seal surface and the outside flank of the groove on initial
assembly. To ensure a reliable metal seal, the 6B and 6BX connector designs produce contact bearing
stresses at the 23° mating surfaces that are many times higher than the rated working pressure.
As the flange bolting is made up, the narrow 23° gasket seal surfaces must slide along the 23° flanks of the
grooves, under very high load. Without lubrication, this could cause damage to the seal surfaces. If the
connection is disassembled and re-assembled for service, lubrication of the metal gasket for assembly is
essential to allow repeated use of the equipment without repair of the ring grooves. Because of the high
bearing stress, the film thickness of lubricant initially applied to the gasket is not critical.
H.1 .2 Bolting Lubrication
To achieve the desired tensile preload in the studs, the stud threads and the bearing face of the nuts should
be well lubricated. Paint thickness should be minimal (e.g. primer coat only) in the bearing areas of the
flange back-face where the nuts contact it. Multipart coating systems have been known to creep over time
under the high crushing loads of the nuts, resulting in leakage.
H.2 Bolt Tightening Pattern
Flange bolting shall be tightened gradually, repeatedly working around the bolt pattern in a “ crisscross ” or
As an alternative, multihead tools may be used per the manuf acturer’ s procedures.

Examples of bolt make-up sequence are shown in Figure H.1 and in ASME PCC-1 .

Figure H.1 —Recommended Bolting Make-up Patterns
H.3 Recommended Make-up Torque
H.3.1 General Principles
It has been shown that the torque values given in Table H.1 and Table H.2 are acceptable values for use in
type 6B and 6BX flanges in some applications.
NOTE Refer to API TR 6AF, API TR 6AF1 , or API TR 6AF2 for data on the effects on flange performance of bolt
preload stress and other factors.
It should be recognized that torque applied to a nut is only one of several ways to approximate the tension
and stress in a fastener.
Table H.1 and Table H.2 are based on calculations that assume certain friction coefficients for the friction
between the studs and nuts, and between the nuts and the flange face.
Some factors that affect the relationship between nut torque and stud stress are as follows:
—
—
—
—
thread dimensions and form;
surface finish of studs, nuts, and flange face;
degree of parallelism between nut face and flange face;
type of lubrication and coatings of the threads and nut bearing surface areas.

Two coefficients of friction are used in the tables. A coefficient of friction of 0.1 3 approximates the friction
with threads and nut bearing surfaces being bare metal, well lubricated. For applications above 260 °C
(500 °F), lubrication shall not contain lead, tin, antimony or bismuth. A coefficient of friction of 0.07
approximates threads and nut face coated with fluoropolymer material.
Lubricants, surface finishes, etc., may influence the accuracy of the actual bolt tension when measuring
torque. Therefore, the torque values listed in Table H.1 and Table H.2 are provided only as an informative
guide. The torque and the make-up practices employed should be verified by the manufacturer.
The tables show material properties equivalent to ASTM A1 93/A1 93M grades B7 and B7M, which are the
most commonly used. Values of torque for materials having other strength levels may be obtained by
multiplying the tabulated torque value b y the ratio of the new material’ s yield strength to the tabulated
material’ s yield strength.

Method of Calculating Tap End Stud Lengths for Type 6B and 6BX Flang es
I.2.1
Calcul ati on
Equation (I.2) is used in establishing tap end stud lengths listed in Table I.3, Table I.4, Table I.5, and Table
I.6 and is included here for convenience of industry. Length shown in tables results from rounding as
specified in I.2.2.
L = T + t + d + S + P + TL + RF
(I.2)
where
L
is calculated tap end stud length;
T is total flange thickness;
t
is plus tolerance for flange thickness;
d
is heavy hex nut thickness (equals nominal bolt diameter; see ASME B1 8.2.2);
S
is flange face standoff; S = 0 for BX assemblies [see Table D.8 (groove)/Table E.8 (groove) and
Table D.9 (gasket)/Table E.9 (gasket) —Type R and Table D.1 0 (gasket)/Table E.1 0 (gasket) —Type
RX];
P is maximum end point height (1 .5 x pitch of thread);
TL is tap end thread length, maximum [(one diameter + 1 .5 pitch) + 1 /1 6];
RF add amount of raised face present on studded flanges, if not omitted, to the length of studs in table.
I.2.2
Roundi ng off Procedure
Add 1 /1 6 in. to the calculated length and then round up to the next 1 /8 in. increment after this addition. This
rounding procedure allows for variation in stud installation methods and ensures sufficient extension for full
nut engagement.
I.2.3
Endpoint Hei g ht of Tap End Studs
The endpoint is the end portion of a stud bolt beyond the complete thread and may be chamfered, rounded,
or sheared. The maximum height of each endpoint shall be 1 .5 x pitch of thread.
I.2.4
Tap End Thread Leng th
One diameter of tap end stud + 1 .5 pitch of thread, with a tolerance of + 1 /1 6 /− 0 (this includes point height).
I.2.5
Nut End Thread Length
2.5 x diameter of tap end stud minimum. However, if necessary, this length shall be limited to provide
minimum unthreaded portion equal to one thread pitch between the tap end threads and nut end threads.
I.2.6
Flange Face Standoff Values,
S
The approximate distance between faces of made-up flanges, S (see Figure I.2) is given in Table D.9/Table
E.9 —Type R gasket and Table D.1 0/Table E.1 0 —Type RX gasket.

Annex L
(informative)
Segmented Flanges
L.1
General
NOTE 1 Segmented flanges for dual completion are included in this specification to provide interchangeable
replacement equipment for existing installations.
NOTE 2 Segmented flanges are of the ring-joint type and are designed with the ring groove in a recessed
counterbore. Depending on tolerances and whether the gasket has been properly seated, the connection make-up
bolting force can react on the surface outside the recessed face of the flange.
The segmented flange shall be of the through-bolted or studded design.
NOTE 3
Face-to-face contact is not necessary for the proper functioning of segmented flanges.
L.2 Dimensions
Segmented flange dimensions shall conform to Table L.1 or Table L.2. Ring groove dimensions shall
conform to Table D.1 0/Table E.1 0.
L.3 Flange Face
The flange face shall be fully machined. The nut-bearing surface shall be parallel to the flange gasket
counterbored face within 1 °. The back face may be fully machined or spot-faced at the bolt holes.
L.4 Gaskets
Segmented flanges shall use RX gaskets specified in Table L.2 that conform to the requirements of 1 4.2.
L.5 Corrosion-resistant Ring Grooves
Corrosion-resistant ring grooves manufactured in segmented flanges shall meet the specified minimum yield
strength of the base material.
L.6 Service Limitations
These flanges shall not be used for H 2S service, and shall not be marked with material classes DD, EE, FF, or HH.
NOTE
The use of these flanges for gas service with or without H 2 S is not recommended.
L.7 Installation
Segmented flanges should be used in pairs (i.e. two flanges side-by-side, for dual completions). Manifolds
should be rigidly clamped together to add stability to the flanges when subjected to bending loads.

Annex M
(normative)
Heat-treat Equipment Survey
M.1 Temperature Survey Method for Batch-type Furnaces
The furnace working zone shall be defined by the manufacturer. A temperature survey within the furnace
working zone(s) shall be performed on each furnace at the maximum and minimum temperatures for which
each furnace is being used.
For furnaces having a working zone less than or equal to 0.3 m 3 (1 0 ft3), a minimum of three thermocouples
located either at the front, center and rear, or at the top, center and bottom of the furnace working zone shall
be used.
For furnaces having a working zone greater than 0.3 m 3 (1 0 ft3) and not greater than 31 .5 m 3 (1 1 25 ft3), a
minimum of nine thermocouples shall be used. For each additional 3.5 m 3 (1 25 ft3) beyond 31 .5 m 3 (1 1 25 ft3 )
of furnace working zone surveyed, at least one additional thermocouple shall be used, up to a total of
40 thermocouples. The first nine thermocouples shall be located as per Figure M.1 and Figure M.2. Each
additional thermocouple location shall be equally spaced in the central additional working zone volume.
After insertion of the temperature-sensing devices, readings shall be taken at least once every three minutes
to determine when the temperature of the furnace working zone approaches the bottom of the temperature
range being surveyed.
Once the furnace temperature has reached the set-point temperature, the temperature of all test locations
shall be recorded at two-minute intervals, maximum, for at least 1 0 min. Then, readings shall be taken at
five-minute intervals, maximum, for sufficient time (at least 30 min) to determine the recurrent temperature
pattern of the furnace working zone.
M.2 Temperature Survey Method for Continuous-type Furnaces
Furnaces used for continuous heat-treatment shall be validated in accordance with procedures specified
in SAE AMS2750 or SAE AMS-H-6875.
