ment when used in the manner and for the purpose recommended by PHS. PHS does not warrant goods manufac-
tured by other parties, except to the extent that such goods are covered by a warranty to PHS. Notice of a claim for a
breach of a warranty must be given to PHS within thirty (30) days after the date that the Buyer first has knowledge
of an alleged breach of warranty, but in no event later than one (1) year after the date of shipment. PHS’s obligations

In the event that PHS provides engineering design or fabrication services, the Buyer’s acceptance of PHS’s design
or delivery of the products shall relieve PHS of all further obligations with respect to such design and fabrication,
except to the extent that PHS may otherwise expressly provide in a product warranty. In no event, shall PHS be

SIZE AND SERIES SELECTION PROCEDURE EXAMPLE:

Select a Variable Spring for the following conditions:
The key criteria in selecting the size and series of a Variable Hot Load = 307 lbs. or 1366 N or 139 Kg
Spring support is a factor known as Variability. This is a cal- Movement = 1⁄2" up or 13 mm or 13 mm

the Cold (Installed Condition). The formula is shown below. SOLUTION:
For practical purposes this percentage relates to the amount

to operation. The lower the Variability the lower the effect 0.20 x 307 lbs. = 122.8 lbs. per inch, or

(A Size 5, Series 920 fits the criteria).
% Variability = Variability x 100
3. Calculate the Cold Load.

The Cold Load is calculated by adding (for UP movement) 63 lbs. per inch x 0.50 inches = 32 lbs., or
or subtracting (for DOWN movement) the product of Spring
Rate times the Movement to or from the Hot Load. 11 N per mm x 13 mm = 143 N, or
If an allowable Variability is not specified, good practice 1.12 Kg per mm x 13 mm = 15 Kg

Since the Movement is UP, add the above load change to

4. Calculate the Cold Load and check that both the Hot
Load and Cold Load fall within the Working Range of the
Travel Series selected.
5. If your requirements are not met, move to an adjacent
Spring Size column and recalculate again using the above
procedure.
If the Movement or loading requirements cannot be satis-
fied, select a Travel Series with a greater Working Range
and recalculate.
If any combination of Load, Movement and/or Variability
cannot achieve the desired results the use of a Constant
Support should be considered.

Load, Movement and Direction of Movement (from the Cold/Installed position to
the Hot/Operating position), and Hanger Identification Number (if any). Specify
any other optional feature(s) as necessary.
Pins for attachment to the structure are not included with the unit and must be
ordered separately as a Figure 291, shown on page 8 of this catalog. For ordering
specify Figure Number, pin diameter and finish.
For corrosion resistant units specify the Figure Number with the letter prefix “C”,
e.g. C910
For metric units specify the Figure Number with the letter prefix “M” e.g. M910 or
MC910.

** The Installed Height should be the mid-point between the Maximum and Minimum Overall
Height "X" , plus the thickness of the Load Flange, and plus any DOWN piping movement
when applicable.

Ordering: Specify Figure Number (Travel Series), Type, Size, Hot Load, Cold Load,
Movement and Direction of Movement (from the Cold/Installed position to the
Hot/Operating position), Dimension X (Installed Height) and Hanger Identification
Number (if any). Specify any other optional feature(s) as necessary.
For corrosion resistant units specify the Figure Number with the letter prefix “C”, e.g. C940
For metric units specify the Figure Number with the letter prefix “M” e.g. M940 or MC940.

CALCULATING OF PIPING INSULATION WEIGHT

The weight per foot of insulation is calculated by using the weight
factor “X” from the table below and multiplying by the insulation
density (lbs/cu-ft).

EXAMPLE: A 16" pipe with 31⁄2" of insulation is found to have a

weight factor of 1.49 (from table below). With an insulation density of
11 lb/cu-ft, the calculation for insulation weight is 1.49 x 11 = 16.39

General Formula: For pipe sizes not shown in the table above (special
O.D. pipe, etc.), use the following formula to determine the insulation weight:
Insulation Weight: (lb/ft) = 0.0218 x I x T x (T + D)
Where: I = Insulation density (lb/cu-ft)
T = Insulation thickness (inches)
D= Outside diameter of pipe (inches)
