Experience & Innovation
S
ince June 1991, a new name has been forging the future of the cryogenic industry; PHPK
technologies. Though the name is new, it represents some of the most talented and experienced
minds in applied cryogenics. The main thrust of this organization is to supply
state-of-the-art, industrial class cryogenic equipment and systems.
Founder James G. Pierce is well-known for the
development of the highly successful former
CryoVac Inc./CVI Inc. organization. Pierce has taken
his 42 years’ experience and top technical experts and
formed PHPK, with a vision of a new leader in the
cryogenic industry.
Today, PHPK develops and manufactures standard
product components, transfer line systems, and
machinery for the cryogenic industry based on
advances in design concepts, material properties, and
manufacturing technology. These developments
include a new line of reciprocating cryogenic
expansion engines, a reciprocating cold compressor
suitable for service down to 3°K, and a modular
design helium refrigerator/liquefier product line
with 3-16 liter per hour equivalent capacity. These
units operate without the need for LN2 precooling
and with a standard, integrated control system that
allows for remote monitoring and control.

Vacuum Jacketed Transfer System Design Guide
As an aid in developing your vacuum jacketed system, PHPK offers the following approach to design
and specification.
During the planning stages of the system, allow adequate time to engineer, design, and fabricate a
custom piping system. Vacuum jacketed piping should not be viewed as conventional plumbing.
Contact PHPK to help establish schedules.
Establish the basic routing of the system, allowing clearances for installation, valves, and other
systems current and future.
Complete an isometric sketch or plan and elevation drawings to aid in determining exact
components required. Be sure to note wall or roof penetrations and installation restrictions.
On complex systems, include a P&ID.
Size the pipe and components using expected current and future flow rates. Initial installations
should plan for potential future expansion.
Consider features such as:
• larger mains and branches for high-usage areas,
• smaller branches for lower-usage areas,
• flexible sections for field adjustment, congested areas, alignment problems, special angles, and
disassembly,
• vacuum jacketed in-line valves for system or function shut-down or flow control,
• capped bayonet couplings for future expansion,
• internal trapped drops for reduced heat leak and fast system response,
• relief devices for trapped volumes.
Refer to PHPK Vacuum Installation Piping Specification for a procurement specification guideline.
Call PHPK for design assistance.

Vacuum Jacketed Transfer Systems for
Liquid and Gaseous Helium
PHPK also fabricates vacuum jacketed piping systems for liquid helium service, where heat leak and
final system design are of prime importance to performance and economic operation. PHPK utilizes
the same attention to quality, design, and performance as with other vacuum jacketed systems, with
special considerations for insulation, spacer supports (inner line to jacket), and component design
such as extended-length valves and bayonets. With modifications to standard designs, PHPK helium
systems provide an economic approach to low heat leak helium requirements without significant
increases in system cost.
For ultimate performance with specialty helium systems, PHPK makes liquid nitrogen/cold helium
gas-shielded systems available. These systems are economically justified only where the transfer lines
require many components, such as valves and bayonets, with ultra-low total heat leak requirements.
The shielded piping provides a means of heat stationing components to reduce heat leak in addition to
the increased thermal performance provided to the piping. These systems are very specialized and
should be considered only where the ultimate performance is required. PHPK engineering will aid
you in your design and specification requirements for helium systems, shielded and non-shielded.
The following engineering data is supplied to help in establishing helium transfer system
requirements. Actual performance will depend upon final configuration and design.

2.4
Non-Destructive Testing (NDT)
All components and piping testing will meet code requirements as a minimum. When the code does
not regulate testing, such as vacuum integrity, PHPK engineering/design staff will require NDT to
meet quality standards set down by this specification/customer specification and contract.
2.5
Safeguards (Appendix “G” ANSI/ASME B31.3)
When required by the customer ’s specifications, PHPK engineering/design will give appropriate
consideration to safeguarding the system.
3.0
MATERIAL AND COMPONENT SELECTION
PHPK will use only code-qualified components and materials as defined in Chapter III and Chapter
IV, Table 326.1 of the ANSI/ASME B31.3 and/or as listed in Appendix “A,” for use within the system
and component temperature limits. All PHPK material components will be of new, traceable origin.
No used material or material of unknown origin will be permitted.
3.1
Inner (Process)
Process pipe will be fabricated using Type 304/304L (dual graded), ASTM A-312 stainless steel pipe,
welded or seamless. Tubing will be fabricated using Type 304/304L or (dual graded), ASTM A-269
stainless steel tube welded or seamless.
3.2
Vacuum Jacket
Piping used for the vacuum jacket will meet the same requirements as the inner pipe and will be
schedule 5 or greater, the wall thickness will be in conformance to Section VIII, Division 1, of the
Boiler and Pressure Vessel Code, paragraph UG-28.
Where heavier wall is required for pipe supports or anchors, PHPK engineering will review and
reinforcements will be added to meet design conditions.
3.3
Fittings
Inner-line fittings will be butt weld and will conform to ASTM A-403 WP-W or A-403 WP-S, grade
304/304L stainless steel. Flanges will conform to ASTM SA-182, grade 304/304L stainless steel.

3.3.1 Valves
Vacuum jacketed valves will be PHPK manufactured, which conform to the pressure rating, material,
and other design features required to meet specified service. All cryogenic extended-stem globe
valves will be PHPK model ________. Castings will be lost wax investment cast, ASTM-A-743,
grade CF3 (304L) stainless steel, zyglo and radiograph inspected. Valve component materials of
construction will be 304L or 300-series stainless steel. Bonnets will be bronze alloy. All butt weld
connections will be “true butt weld” with no closed-end cavities (such as socket weld) which cannot
be easily cleaned for oxygen service. Seal disk material will be PCTFE M400H (Kel-F). Valve barrel
and bonnet bolts will be plated with a PHPK-specified, patented nickel/teflon plating which has been
tested and approved for oxygen service. This plating, unlike chrome, does not chip or flake and
provides a homogeneous surface to prevent galling. The valve design provides a close-tolerance fit
(approximately 0.003”) between the barrel and the body extension tube, allowing operation in any
orientation, even upside-down, while insuring bonnet (Viton O-ring) seals remain warm when the
valve is in cryogenic service. Valves will have self-locking seat seals which do not require staking
or welding for assembly or maintenance.
3.4
Expansion Joints
Piping spools will be designed and fabricated using single-ply external bellows to compensate for
thermal cycling. Bellows material will be type 304, 316, or 321 stainless steel. End connections will be
304/304L stainless steel. The bellows will meet the requirements of the EJMA, (Expansion Joint
Manufacturers Association), and ASME B31.3 for 35 psig internal pressure/20 psig external and 0 psia
internal. Normal movement will not exceed 75% of the maximum rated movement for a design cycle
life of 5,000 complete cycles.
3.4.1 Flexible Components
Flexible hose may be used on the inner line and vacuum jacket to compensate for system movement.
When used, protective braid will be installed on both the inner line and jacket and the design will
meet the manufacturer ’s recommendations and EJMA design.
3.5
Vacuum Closures
Vacuum end closures may be required between the inner process line and the vacuum jacket.
Engineering/design will consider system heat leak, thermal stress, shipping loads, and system
performance requirements while evaluating the type of vacuum closure to be used.
3.5.1 Cryogenic Couplings (Bayonets)
When bayonet connections are used they will be PHPK design. All male and female bayonets will be
close-tolerance fit (0.003” to 0.004”) between matching parts and will utilize a warm gas vapor O-ring
seal. Coupling flange will be designed to accept V-band or flanged connection, as specified. Bayonets
will be mass spectrometer leak-tight and will have no unsealed cavities (such as socket welds) which
can trap contaminants and cannot be totally cleaned for oxygen service. All male parts are to be plated with a licensed, patented, oxygen-compatible, PHPK-specified, anti-galling coating.

3.6
Inner Pipe Supports (Spacers)
The inner (process) pipe will be centered within the vacuum jacket by a support system designed to
transfer the loads between the two (2) pipes during thermal cycles with the inner line filled with
process fluid, as well as during shipment. In addition to thermal and shipping loads, the spacer
configuration will be designed to minimize heat leak into process pipe.
3.6.1 Spacer design will withstand the following loading during shipment and after
installation:
• Three (3) “g” load applied vertically downward
• Three (3) “g” load applied vertically upward
• Two (2) “g” load applied horizontally (longitudinally or laterally) combined with a one
(1) “g” load vertically downward
• Meet the uniform building code for zone 4 seismic requirements with the inner line
filled with process fluid
3.7
Laminar Radiation Shielding (Superinsulation)
The inner (process) pipe will be wrapped with a minimum of sixteen (16) alternative layers of
aluminized mylar, (aluminized both sides, 32 reflective layers), and glass fiber insulation.
3.8
Chemical Gettering System
Each spool assembly will have a chemical gettering system installed during fabrication. The
system will consist of a calcium zeolite desiccant, (Linde Type 5A molecular sieve), and a hydrogen
converter such as palladium oxide. The quantity of each material in the gettering system will be
determined by PHPK based upon the diameter and length of the spool.
In oxygen service, special provisions will be made to isolate the hydrogen converter from
contacting other inner line materials.
3.9
Evacuation Port (Vacuum Seal-off)
Each pipe spool assembly will be fabricated with a PHPK seal-off and relief valve (Model VR-46),
bellows-sealed isolation valve, and a thermocouple vacuum gauge tube. Each PHPK seal-off
valve is all-stainless steel construction, equipped with a double O-ring seal to prevent vacuum loss
from vibration or shock, and a threaded spring O-ring sealed relief cap to prevent moisture and
contamination from entering the valve internals. Stainless-to-stainless threads will be plated and
protected from galling and corrosion with a PHPK-specified, patented nickel/teflon plating. The
seal-off valve assembly provides a combination pump-out opening, seal-off, and relief device. The
seal-off port assembly will be positioned on each spool in an approved location considering safety,
accessibility to pump-down devices, and non-interference with neighboring equipment. Each
thermocouple gauge tube assembly will be covered to prevent damage while in service.

3.9.1 Vacuum Gauge Tubes/Isolation Valve
Each spool will be equipped with a thermocouple vacuum gauge tube to monitor the vacuum level
without breaking into the vacuum annulus. A bellows seal isolation valve will be placed between the
vacuum annulus and the thermocouple gauge tube to isolate the tube for maintenance.
4.0
FABRICATION
Piping will be fabricated in a clean, well lighted air-conditioned shop, in such a manner as to prevent
undetermined stresses due to springing or forcing. Pipe ends will be cleaned and properly prepared
to meet the code requirements for connection.
4.1
Welding
All welding will be performed by welders who have been qualified to procedures and positions as
required by ANSI/ASME Section IX, Article II, of the Boiler and Pressure Vessel Code for the material,
temperature, and application intended. PHPK shop welding standards will meet the requirements of
ANSI/ASME B31.3 Piping Code, Chapter V for full-penetration welds.
4.2
Welding Equipment
Welding will be performed using GTAW, GMAW, or orbital welding. The shielding gas may be argon,
helium, or any procedure-approved mixture. Filler metal will comply with the procedures.
4.3
Cleanliness
Work areas will be maintained in a clean orderly manner. Piping and components will be cleaned
with an environmentally-approved cleaning solvent inside and out prior to welding and after all
cutting, grinding, or filing. All burrs, grease, oil, and metal residue will be removed prior to welding.
The outside of the inner line will be cleaned prior to the installation of laminar radiation shielding.
The inside of the vacuum jacket will be cleaned prior to installation.
Prior to final assembly and testing, the annular space of all vacuum jacketed piping will be thoroughly
cleaned to remove contamination and hydrocarbon residue. This cleaning will be performed on all
piece-parts using PHPK-designed and fabricated system which pressure circulates, filters, and heats a
cleaning solution authorized by the USDA for use in federally-inspected meat and poultry plants and
is environmentally safe. In addition, each piece is individually inspected prior to rinsing in a pressure
circulating rinse tank. All parts are completely air-dried prior to starting final assembly.
4.3.1 All surfaces to be cleaned will be completely wetted by means of immersion, circulation,
flushing, spraying, or swabbing and dried with dry GN2 or dry, oil-free air.
4.3.2 Cleaned surfaces will be visually inspected for contamination, scale, or rust. Discoloration due
to welding will be acceptable. Any visual sign of contamination will be cause for recleaning the part.
4.3.3 White cloth, ultra violet, and special cleaning procedures will be dictated by the customer
contract and specification requirements and will be addressed in separate specifications. Ultra violet
light examination for oxygen service will be addressed in Paragraph 7.1.

5.0
INSPECTION AND TEST
All inspection and testing will be directed by the Quality Assurance Manager and will meet the
requirements of the PHPK Quality Assurance Manual and contract-related specifications. Quality
Assurance is a function and requirement of each employee of PHPK. Final review of materials certification, welders qualification, record and test examination, and maintenance of records falls
under the direction of the Quality Assurance Manager.
5.1 Required Examination
Examinations required by the ANSI/ASME B31.3 Piping Code are:
• Visual Examination
• Random Radiography
• Component and material certification records
5.1.1 Radiography
Five (5) percent of all inner line butt welds will be random radiographed. Radiographs will be read
and reader sheets will be prepared in accordance with the code by certified technicians.
5.1.2 Pressure Testing
All inner lines will be either pneumatically (not less than 125% of design pressure) or hydrostatically
(not less than 150% of design pressure) pressure tested. Test pressure, medium, and time duration
will be directed by engineering/design and customer requirements.
Pneumatic testing is preferred because of reduced chance of inner line contamination, and when performed with a combination of nitrogen and helium gas, while mass spectrometer leak testing, this
method provides more accurate leak detection.
5.2
Supplementary Examination
Supplementary examination, beyond code requirements, will be detailed in separate specifications
and performed as directed by engineering/design. Specifications will include type of inspection/
tests, procedure or method, standard, and acceptance criteria.
5.3
Dimensional
Upon completion of fabrication, each spool assembly will be dimensionally inspected to verify that
dimensions meet engineering design. At the same time, each assembly will be visually inspected for
workmanship, material conditions, and completeness.
5.4
Combination Pressure/Mass Spectrometer Leak Test
5.4.1 With the spool seal-off valve connected to a Mass Spectrometer Leak Detector, with the
sensitivity calibrated to 1 x 10-9 scc/sec, evacuate the annular vacuum space.

5.4.2 Blank off the inner line for pneumatic pressure test. The inner line will be pressurized with a
mixture of 90% dry nitrogen gas and 10% helium gas. Proof pressure will be reached in 25% steps
with each step pressure-held for two (2) minutes and the vacuum gauge monitored for increased
pressure. The final proof pressure will be held for ten (10) minutes and the vacuum level monitored.
Any change in pressure indicates a leak.
5.4.3 Upon completion of the pressure test, the pressure will be reduced to maximum design
working pressure and the vacuum space (inner line welds) will be tested using the mass spectrometer.
At the same time, the jacket welds will be sprayed or bagged with helium gas. Inner line welds not
enclosed by the vacuum jacket will be soap bubble tested for leaks.
A no-leak indication by the mass spectrometer at 1 x 10-9 constitutes a successful test.
5.4.4 Upon completion of the pressure/leak test, the vacuum annulus will be brought back to
atmospheric pressure by slowly backfilling with dry nitrogen gas. Likewise, the inner line pressure
will be released slowly.
6.0
EVACUATION
Upon the successful completion of the pressure and mass spectrometer leak test, each spool will
undergo bake-out and evacuation.
6.1
Each line will be heated to between 212o and 250o F by forcing filtered and heated air
through the inner line while the vacuum jacket is covered with insulating blankets. The inlet and
exit temperature of the bake-out will be monitored and recorded. Each individual line temperature
will be monitored to ensure proper exit temperature of the individual spool section.
6.2
Upon reaching the prescribed temperature (generally one (1) day), evacuation of the annular
space is started using a mechanical fore pump connected to the system through a diffusion pump
and LN2 cold trap to prevent oil from back-streaming. Heating and pumping are continued until the
spool vacuum is at approximately zero (0) microns. The time period is determined by the piping size
(volume of the annular space) and the history of time/pressure reduction in reaching the zero-micron
level. Total time for bake and evacuation is approximately five (5) to seven (7) days.
6.3
Vacuum Retention Test
The vacuum retention test will start after the vacuum seal-off valve has been closed and the spool
has returned to ambient temperature. The pressure of each spool will be measured and recorded
every 24 hours using the thermocouple gauge tube. Each vacuum reading will be recorded with
date, time, and ambient temperature. The minimum test period will be seven (7) days, unless
otherwise authorized by the customer/PHPK engineering.

1 -19
6.4
Test Acceptance
The vacuum retention data is to be interpreted as follows:
6.4.1 If daily readings remain unchanged, other than effects of temperature variations, the spool is
acceptable.
6.4.2 If daily readings increase less than two (2) microns per day for the first part of the test,
followed by a period of no change, the spool is considered acceptable as long as the final maximum
stabilized reading is below 30 microns.
6.4.3 A continuous pressure increase throughout the retention period indicates a leak. The spool
will then undergo additional mass spectrometer leak testing until the cause can be found and
corrected. The spool will then be baked out and re-evacuated, as required, and subjected to an
additional retention test.
6.4.4 Normal retention test readings are 15 microns or less after seven (7) days with the last four (4)
to five (5) readings stable. Some fluctuations may appear in the last readings attributed to ambient
temperature changes or simple out-gassing. Any spool reading over 15 microns, but not over 30
microns with the last readings unstable, may be recycled through the baking/retention sequence or
cold-shocked for one (1) hour using LN2 while monitoring the vacuum level.
The cold-shocked spool can be considered acceptable if the vacuum level is “off scale” (less than
1 x 10 -3 torr) during the one (1) hour test.
7.0
FINAL CLEANING
All process surfaces will be final cleaned as required, after final welding, machining, threading,
pressure testing, and final evacuation. All components will be pre-cleaned and also progressively
cleaned during fabrication. Final cleaning applies only to areas and procedures which may be
contaminated during fabrication.
7.1
Ultra Violet Light Examination
All cleaned, exposed exterior surfaces, and interior surfaces to the physical extent possible, will be
examined under ultra violet lamps while in a dark or subdued light. Any evidence of fluorescence
(which may indicate presence of hydrocarbons) will be cause for rejection and recleaning. Fluorescent
specks due to lint or mildly fluorescent stains from detergent residues are acceptable, except in excess.
7.1.1 Where direct ultra violet is ineffective, the wipe technique will be used. The surface will be
rubbed in opposite directions with a clean, white paper or lint free cloth which will then be re-examined under both bright and ultra violet light. Excessive discoloration or bluish-white fluorescence will
be cause for rejection and recleaning.

7.2
Required Recleaning
Parts or assemblies rejected for cleanliness will undergo complete or spot recleaning as required.
Re-examination is required after recleaning.
8.0
PACKING/SEALING
Pipe ends will be sealed with polyethylene sheets or bags to a minimum of one (1) inch onto the
jacket closure, and sealed with water-proof tape. Ends will then be treated appropriate to the degree
of protection required to prevent damage during shipment. This may be plywood backing flanges
(flange connections), foam wrap (over the nose of bayonets), or other protection as necessary. An
additional polyethylene sheet will be taped into place as the outermost wrap. Threaded ends will be
protected with “Ca Plugs,” or equal prior to applying the final seal. Additional packaging and sealing
requirements may be specified by engineering/design and/or customer contract.
9.0
LABELING
Each spool will be labeled with a PHPK self-adhesive, aluminum anodized (Photofoil) label. The label
will be placed near the vacuum seal-off valve and will contain the appropriate information to identify
the spool part number, service, etc.
Spools cleaned for oxygen service will be labeled with an additional label indicating “cleaned for
oxygen service.”

Double-Containment Piping Systems
Current environmental laws regulating the transportation and distribution
of hazardous waste and chemicals have increased the need for doublecontainment piping distribution systems.
The United States Environmental Protection Agency issued the CFR Subpart
D-Release Detection, 280.40, in 1988 which requires secondary containment
for hazardous substances contained in tanks and
piping distribution systems. These systems,
including all underground piping, must have
secondary containment and be checked on a regular
basis to prevent the release of these substances.
Because
PHPK’s
capabilities
include
fabrication of a
variety of exotic materials,
extensive engineering and
design abilities, and a quality
control system which meets
stringent governmental requirements, PHPK can supply double
containment piping which meets all
secondary containment applications.
Typical Skin Effect
Double Containment System
Special purpose double-containment systems,
such as skin-effect heated systems, can be
engineered and furnished as required.
PHPK double-containment systems are
all fabricated, tested, and cleaned in our
totally air-conditioned plant. The

Description
PHPK Valves have been engineered, designed, and manufactured using the latest state-of-the-art
technology. All pipe size valves have been fully computer analyzed and tested for a 600 psig,
1
non-shock, WOG rating.
Unique design and manufacturing techniques enable PHPK to offer a variety of valve end connections
including flanged, threaded, socket weld, and true buttweld (important for oxygen cleaning). In
addition, the PHPK valve has no hidden cavities or crevices which can trap contaminates and cannot
be cleaned by normal cleaning techniques. PHPK valves are designed with a fabrication controlled
gas path (.003” to .004”) allowing the use of simple warm O-ring bonnet seals which enable the valves
to be operated in a totally inverted position with cryogen flowing through the valve. Manual valve
(PV-60, PV-90) stem seals are engineered to allow replacement without total system shut-down or
removal of the cryogen from the line. The valve seat seals are installed using a locking design (patent
pending) which eliminates potential seat leakage from improperly installed seals or leakage paths
open to the process stream. The use of state-of-the-art PHPK-specified, patented oxygen compatible
plating techniques eliminates galling of critical components.
All PHPK pipe-size valves are completely interchangeable between manual, remote (on/off), check
valve, and remote flow control, without changing the valve body. All seals on vacuum jacketed valves
can be replaced without disturbing the vacuum. Flow arrows and identification tags are cast into the
valve bonnets 1/2” through 2” NPS to avoid confusion when the valves are vacuum jacketed.

PHPK Pipe Size Valve Ordering Specification
All cryogenic extended-stem globe valves will be PHPK model PV-60, PV-70, PV-80, PV-90 or CV series. All valve
components will be totally interchangeable between valve models and flow characteristics without replacing valve
bodies. Castings will be lost wax investment cast, ASTM A-743, grade CF3 (304L) stainless steel, 100% radiograph
and zyglo inspected. Valve component materials of construction will be 304L or 300-series stainless steel. Bonnets
will be bronze alloy. Valve bonnets will have permanently cast or marked flow arrows when vacuum jacketed.
All butt weld connections will be “true butt weld“ with no closed-end cavities (such as socket welds which can
not be easily cleaned for oxygen service). Weld connection between body extension tube and valve body casting
will be a butt weld connection. Seal disk material will be Neoflon PCTFE M-400H (formerly Kel-F). Valve barrel
and bonnet bolts will be plated with a PHPK-specified, patented nickel/teflon plating, which has been tested and
approved for oxygen service. This plating, unlike chrome, does not chip or flake and provides a homogeneous
surface to prevent galling. The valve design will provide a close-tolerance fit (appoximately 0.003”) between the
barrel and the body extension tube, allowing operation in any orientation, even upside down, while ensuring bonnet (Viton, fluorocarbon rubber, O-ring) seals remain warm when the valve is in cryogenic service. Stem packing
will utilize dual Viton O-rings on the static and dynamic areas of the sealing surfaces. Bonnet seal will be a single
Viton O-ring. Valves will have self-locking seat seals which do not require staking or welding for assembly or
maintenance. All vacuum jacketed valves will be serviceable without breaking vacuums. Stem packing in manual
valves (PV-60, PV-90) will be replaceable without removing the valves from service.

PHPK Cr yogenic Globe Valves
The flow characteristic of a control valve is considered to be the relationship between the flow
rate through the valve and the valve travel as the travel is varied from 0 to 100%. “Inherent flow
characteristic” refers to the characteristic observed with a constant pressure drop across the valve.
The “installed flow characteristic” is obtained in service where the pressure drop varies with flow
and other changes in the system.
The purpose of characterizing control valves is to provide for a relatively uniform control loop
stability over the expected range of the system operating conditions. To establish the flow
characteristic needed to “match” a given system requires a dynamic analysis of the control loop.
Analysis of the more common processes have been performed to establish some useful guidelines
for the selection of the proper flow characteristic. The following is a look at the flow characteristics
in use today:
Discussion of Flow Characteristics
The accompanying graph illustrates typical flow
characteristic curves. The quick opening flow
characteristic provides for maximum change in
flow rate with minimal stem travel, while
maintaining a fairly linear relationship.
100
90
80
70
Additional increases in valve travel give
sharply reduced changes in flow rate, and when
the valve plug nears the wide open position,
the change in flow rate approaches zero. In a
control valve, the Quick Opening valve plug is
used primarily for on-off service, but it is also
suitable for many applications for which a
Linear valve plug would normally be specified.
PHPK models PV-60, PV-70, and CV (check
valves) have quick opening plugs.

TRAVEL, PERCENT
The linear flow characteristic curve shows that
the flow rate is directly proportional to the valve travel. This proportional relationship produces
a characteristic with a constant slope so that with constant pressure drop, the valve gain will be the
same at all flows. (Valve gain is the incremental change in flow rate produced by a corresponding
incremental change in valve plug position. Gain is a function of valve size and configuration,
system operating conditions and valve plug characteristic.) The Linear valve plug is commonly
specified for liquid level control and for certain flow control applications requiring constant gain.
PHPK models PV-80 and PV-90 are available with linear flow plugs.

2 -4
In the equal percentage flow characteristic, equal increments of valve travel produce equal percentage
changes in the existing flow. The change in flow rate is always proportional to the flow rate just before
the change in valve plug position is made. When the valve plug is near its seat and the flow is small,
the change in flow rate will be small; with a large flow, the change in flow rate will be large. Valve
plugs with an equal percentage flow characteristic are generally used on pressure control applications,
and on other applications where a large percentage of the pressure drop is normally absorbed by the
system itself, with only a relatively small percentage available at the control valve. Equal percentage
valve plugs should also be considered where highly varying pressure drop conditions can be expected.
PHPK models PV-80 and PV-90 are available with equal percentage flow plugs.
It should also be noted that although PHPK flow control valve models PV-80 and PV-90 have shut-off
capability, a flow control valve should not be installed in a system as a shut-off valve.

Note: The term CV is generally used by industry for comparing and calculating relative flow capacity
in valves. Consideration should be given that calculated results are comparative only.

Definitions: CV equals the number of gallons per minute of water, having a specific gravity of 1.0, that
will pass through the valve with a pressure drop at the valve of 1 PSI.
CV = valve flow coefficient
P1 = upstream pressure in PSIA
P2 = downstream pressure in PSIA
* P = pressure drop or differential (p1-p2) in PSI

Note: The flow capacity of a valve is defined by its Flow Coefficient (CV ), which is virtually constant
for any inlet pressure, pressure drop, temperature, flow rate, or fluid medium. The CV is equivalent to
the number of gallons per minute of water, having a specific gravity of 1.0, passed by the valve with a
1 PSI pressure drop.

Quality Tested and Proven
All PHPK valves are thoroughly tested and promise proven field performance. In addition to
requirements for chemical and physical material certifications on all raw material and castings,
additional performance tests are required by PHPK to guarantee the highest quality valves for cryogenic and vacuum service.
Quality Tested
Body castings 100% radiographed
Body castings 100% liquid penetrant (Zyglo)
inspected
Proof pressure tested to code requirements
Leak tested across the seat
Mass spectrometer leak test at 1 x 10-9 scc/sec
helium
Operational test prior to shipment
Commercially cleaned using a pressure circulated,
filtered, PHPK-developed system
Specialty cleaning available on request
PHPK tests all valves utilizing PHPK-designed and
developed test equipment.
In addition to raw material tests, operational and
performance tests, PHPK valves have been proven
as a performance leader by independent
government tests.
Conclusions
The test article was subjeted to 3 runs of cryogenic leak checks and 2 runs of ambient cycling
for a total of 1,120 acutation cycles. The valve was found to be bubble-tight helium at -320
degrees F and 250 psig. The handwheel torque required for bubble-tight shut-off at a given
inlet pressure was highly repeatable. The valve and manual operator worked smoothly and
consistently through all actuation cycles.

Stress Analyzed
Complete and detailed stress analysis has been completed for the entire PHPK product line of
cryogenic valves. Finite Element models of this product line have been developed and subjected to
thorough analysis. Not only the valve bodies, but the barrel and extension tubes of all of these valves
are included in the analysis.
Results demonstrate that even the most critical local stresses in the valve bodies do not exceed 75% of
the material Basic Allowable Stress at the design pressure of 600 psig. Further results demonstrate
that the most critical local stress expected at the elevated test pressure of 900 psig (150% of design
pressure) is only 73% of the Yield Stress.
Analysis Methodology
Finite Element modeling and analysis have been developed and analyzed using a commercially
marketed and widely used personal computer based system. All the analysis are linear (e.g., assume
stress/strain remains in the elastic range and strains are relatively small). PHPK drawings have been
modeled.
All material properties have been taken from ASME Standards and incorporated in the computerbased Materials Library for analysis purposes.
Conclusions
Using contemporary Finite Element Analysis techniques, PHPK cryogenic valves have been subjected
to thorough and critical stress analysis. Detailed stress distributions clearly indicate the areas of highest stress with even the most critical criteria demonstrating that all the valves meet the design criteria
for the specified design pressure of 600 psig. Furthermore, the results also demonstrate that all of
these valves will satisfactorily pass the 900 psig Pressure Test.

TUBE SIZE CR YOGENIC GLOBE VA LVES
Description
The PHPK tube-size cryogenic globe and angle valves are manufactured with the same
attention to detail and quality as their pipe-size counterparts. All manual tube-size valves
employ smooth acting acme threads and six-bolt bonnets. Remote valves are designed to
accept a variety of actuators. All tube-size valves employ close tolerance barrel design, dualseal warm O-rings, and all of the unique plating and other PHPK design features of the pipe
size valves. Although designed primarily for on/off service, the PHPK tube-size valves can
be modified for flow control.
All specialized testing and material controls applicable to other PHPK valves are not relaxed
during the manufacture of the tube-size valve. This includes a unique one-piece seat design
which can be field replaced in minutes and guarantees bubble tight shut-off.

PHPK Tube-Size Valve Ordering Specification
All cryogenic extended-stem globe valves will be PHPK model TV-11, TV-13 or TV-85 series. All valve
components will be totally interchangeable between valve models TV-11 and TV-13. Castings will be lost wax
investment cast, ASTM A-743, grade CF3 (304L) stainless steel, radiograph and zyglo inspected. Valve component materials of construction will be 304L or 300-series stainless steel. Bonnets will be bronze alloy. All butt
weld connections will be “true butt weld“ with no closed-end cavities (such as socket welds which can not be
easily cleaned for oxygen service). Weld connection between body extension tube and valve body casting will
be a butt weld connection (TV-11 and TV-13 only). Seal disk material will be Neoflon CTFE M-400H, (formerly
Kel-F). Valve barrel and bonnet bolts will be plated with a PHPK-specified, patented nickel/teflon plating,
which has been tested and approved for oxygen service. This plating, unlike chrome, does not chip or flake and
provides a homogeneous surface to prevent galling. The valve design will provide a close-tolerance fit (approximately 0.003”) between the barrel and the body extension tube, allowing operation in any orientation, even
upside down, while ensuring bonnet (Viton, fluorocarbon rubber, O-ring) seals remain warm when the valve is in
cryogenic service. Stem packing will utilize Viton O-rings on the static and dynamic areas of the sealing surfaces. Bonnet seal will be a single Viton O-ring. Valves will have one-piece seat seals which do not require staking or welding for assembly or maintenance. All vacuum jacketed valves will be serviceable without breaking
vacuums. Stem packing in manual valves (TV-11) will be replaceable without removing the valves from service.

Helium Ser vice Valves
Like our standard cryogenic globe valves, PHPK helium service valves have been engineered,
designed, and analyzed to provide the optimum in service and reliability to the specialized
helium market where low heat leak and high quality are standards. Patterned after the standard service valves, all PHPK helium valves utilize all butt welded design for wetted surfaces.
End connections are available in a variety of configurations. Pipe-size valves have undergone
complete computer analysis and have been tested for a 300 psig, non-shock, WOG rating1.
Tube-size valves are rated at 150 psig, non-shock, WOG rating1.
The same unique PHPK designs, materials, and manufacturing techniques are applied to the
HPV/HTV series as to the PV/TV series, including controlled close tolerance gas path (.003” to
.004”), allowing the use of simple, warm, mass spectrometer tight O-ring bonnet seals. PHPK
helium valves are available with bellows seals and intermediate LN2/GN2 heat stations as
options. Completely interchangeable between manual, remote on/off and remote flow control.
Field change-outs can be made without replacing the body assembly. Lower heat leaks are
standard because of increased length, lighter walls, and a unique stem extension design.
Design Features Include:
Higher flow coefficients than other Cryogenic Globe Valves
Low mass for rapid cool-down
Designed for reduced heat leak
Unique seat seals provide positive shut-off
Easy-to-maintain, top entry without vacuum loss
Easy-to-operate, patented plating process and low maintenance materials
allow for smooth operation and reliable service

PHPK Helium Valve Ordering Specification
All cryogenic extended-stem globe valves will be PHPK model HPV-60, HPV-70, HPV-80, HPV-90 or HTV-11/HTV-13 series.
All valve components will be totally interchangeable between valve models and flow characteristics without replacing valve
bodies. Castings will be lost wax investment cast, ASTM A-743, grade CF3 (304L) stainless steel, zyglo and radiograph
inspected. Valve component materials of construction will be 304L or 300-series stainless steel. Bonnets will be bronze alloy.
All butt weld connections will be “true butt weld“ with no closed-end cavities (such as socket welds which can not be easily
cleaned). Weld connection between body extension tube and valve body casting will be a butt weld connection. Seal disk
material will be Neoflon PCTFE M-400H (formerly Kel-F). Valve barrel and bonnet bolts will be plated with a PHPK specified, patented nickel/teflon plating, which has been tested and approved for oxygen service. This plating, unlike chrome,
does not chip or flake and provides a homogeneous surface to prevent galling. The valve design will provide a close-tolerance fit (appoximately 0.003”) between the barrel and the body extension tube, allowing operation in any orientation, even
upside down, while ensuring bonnet (Viton, fluorocarbon rubber, O-ring) seals remain warm when the valve is in cryogenic
service. Stem packing will utilize dual Viton O-rings on the static and dynamic areas of the sealing surfaces. Bonnet seal will
be a single Viton O-ring. Valves will have self-locking seat seals which do not require staking or welding for assembly or
maintenance. All vacuum jacketed valves will be serviceable without breaking vacuums. Stem packing in manual valves
(HPV-60, HPV-90, and HTV-11) will be replaceable without removing the valves from service.

Cr yogenic Couplings
Description
PHPK croyogenic couplings (bayonets) have been engineered, designed, and manufactured to
provide the most reliable connection available for cryogenic vacuum jacketed piping systems.
Manufactured from 304/304L-grade stainless steel, these couplings have special design
considerations to eliminate sweating and frost. All bayonets have been computer analyzed to meet
the ANSI/ASME B31.3 piping code requirements, and stress analyzed to ensure design reliability
and serviceability. All couplings are provided with extended length for low heat leak and all male
bayonets are plated with a licensed, patented, oxygen compatible, PHPK-specified anti-galling
coating. Optional flange connections are available which include V-bands, bolted slip-on, and
threaded connections (tube-size only). Standard seals are fluorocarbon rubber (Viton) O-rings,
however, other compounds and seal materials are available for special applications.
Available in pipe-size (PBA), tube-size (TBA) and for helium applications (HPBA or HTBA).
The PHPK coupling design utilizes a close-tolerance fit (0.003” to 0.004”) between the male and
female to maintain a gas vapor seal which guarantees the O-ring face seal remains warm during
cryogenic transfer. In addition, PHPK couplings have been designed to eliminate cavities existing
in many socket weld design couplings. This is a unique feature which allows total oxygen cleaning
without the worry of trapped contaminants.
All couplings are designed and tested for 150 psig service with special consideration and options
for higher pressure applications. All assemblies are supplied mass spectrometer leak tight to
1 x 10-9 scc/sec helium. PHPK coupling lengths are standardized to eliminate guessing the length
of mating connections when connecting to existing systems.
