VARIABLE SPRING SUPPORTS
INTRODUCTIONThe Variable Support is a spring loaded device used for the
support of piping and equipment where normal verticalmovement is anticipated. Variable Supports are manufac-
tured in five different Travel Series which allow up to ten
inches of movement and twenty-five different sizes allow-ing up to 50,000 pounds of load. Seven different mountingTypes allow the user the widest selection of configurationsto accommodate practically every hanger design.
RECOMMENDED SERVICENormally for support of piping systems where thermalchanges cause the system,dimensions and position to
change, and where load transfer to equipment is not a prob-
lem. Maximum recommended variation from the operating
load is 257o. Aconstant suppofi should be used when
Variability exceeds 257o. Also used for support of equip-
ment and ductwork to customer specifications.
SPECIFICATIONSA11 spring units are designed to meet the requirements of:. ASME Code for Pressure Piping, ASME B31.1, 831.3. Manufacturers Standardizatton Society (MSS), SP-58'
and SP-69. Federal Specification A-A-1 192-A. British Standard BS3974
STANDARD DESIGN FEATURES. Precompression - precompressing the spring coil into the
hanger casing saves headroom by reducing the size of the
casing, reduces the installed envelope size and also
weight and erection time.
' Spring casing protects the coil from damage and weather'. Steel Construction - spring, casing, and internal parts are
fabricated of steel making them rugged and compact' Allwelding is done to the strict requirements of ASMESection IX.
. The Piston Plate serves as a centering device and
guide maintaining coil concentricity under normaloperating conditions.
. Load Indicators are visible in the slots and are
clearly readable.. Stainless steel nameplate and travel scale are
corrosion resistant.. All spring hangers are calibrated for accurate
loading conditions.. The unit is preset at the factory to the Cold Load
upon request.. For each series there is a reserve travel at the upper
and lower limits of the working range of the spring'. Allowable spring coil stresses conform to MSS-SP-58'. Standard finish is a quality rust resisting primer paint.. A turnbuckle or other suitable coupling is utilized
for adjustment of rod type spring units. F type springs
utilize an adjustable load column.. All F type units are supplied with a load flange.
OPTIONAL DESIGN FEATURES. Travel Stop - set at the Cold load position changes the
spring into a rigid support for hydrostatic testing or other
pu{poses. The strength ofthe Travel Stop is designed so
that it can withstand (up to) 2 times the normal load.. Adjustable Travel Stop - allows the resetting of
Preset/Travel Stop at any location within the normaloperating range of the travel.
. Limit Stops - permanently installed to prevent the
movement of the pipe beyond a predetermined distance
or load within the travel range of the spring.. Load Column Guide - for Type F units only, to prevent
tipping of the Load Flange due to anticipated eccentric
loading.. Extended Load Column - for Type F units only, the
length of the load column is furnished longer than nor-mal per customer request.
. Lifting Lugs - are available on larger sizes to facilitateerection and installation.
. Hot-dip Galvanized Finish - available for protectionagainst weather and corrosive conditions. The unit is gal-
vanized to ASTM A-153 except the spring coil which is
epoxy powder coated to assure protection to the coil as itflexes. The load column of the F Type spring is electro-galvanized. Maximum ambient temperature for the epoxy
powdered coating is 350'F (111' C).. Epoxy Paint Finish - available for protection against
weather and corosive conditions. The unit is painted
with a two-part zinc rich epoxy paint except the spring
coil which is epoxy powder coated.. Stainless Steel Construction - allows the greatest
degree of corrosion protection. Constructed completelyof stainless steel except the spring coil which can be
epoxy powder coated for economY.
DETERMINING THE TRAVEL SERIESIn choosing the proper Variable Spring Travel Series itmust first be determined that the calculated movement willfall within the working range of the support and that the
variability of the unit does not induce unacceptable loads
on the other supports or connections. Five (5) standard
Travel Series are available ranging from 17+" through 10".
SIZE AND SERIES SELECTION PROCEDURE
The size of the Variable Spring suppoft selected depends
upon the total piping load to be supported' Complete
sizing information is given on the SIZE and SERIES
SELECTION PROCEDURE shown in this catalog.
DETEHMINING THE TYPE
The type of Variable Spring slrpport to be selected depends
upon the physical characteristics of the structure to which
the hanger assembly will be attached. Consideration must
be given to available headroom, whether the piping will be
supported from above or below the hanger, interferences,
etc. There are ieven (7) standard types available for each
Travel Series; they are:. Tlpe A - Is attached to the supporling member by a verti-
cal rod threaded into the top of the case.. Type B - For use where headroom is limited. The unit has a
single lug for attachment to the stlucture to permit connect-
ing with a bolt or pin to a clevis or welded beam attachment.
VARIABLE SPRING SUPPORTS
. lYpe C - Also designed for limited headroom applica-tions. The unit has two lugs welded to the top of the cas-ing to permit connecting with a bolt or pin through a sin-gle lug attachment to the structure.
. Type D - Designed for use where the variable spring ispositioned above the supporting structure and springadjustment is made from the top.
. Tlpe E - Also designed for use where the variable springis positioned above the supporting structure, but wherethe spring adjustment must be below the structure onwhich the case is supported.
. Type F - Designed to support piping from below. Usedto support pipe from the floor or where supporl fromoverhead is not practical.
. Tlpe G - For irse where headroom is limited or an obstruc-tion prohibits the use of a single rod type Variable Spring.
LOAD PRESET BAR AND TRAVEL STOPThe Load Preset Bars are installed at the factory at the ColdLoad setting of the unit.
The Travel Stops, which are optional and will be providedonly if ordered, include both the Load Preset Bars to pre-set the unit at the Cold Load setting and more imporlantly a
down limit stop which locks the unit at that position.
This locking effect results in the unit functioning as a rigidhanger during erection, hydrostatic testing, chemical clean-ing or other condition which may cause the unit to exceedits load rating. The Travel Stops are designed for twice the
maximum working load of the unit and are installed at thefactory with a "Caution" tag which calls attention to thefact that they must be removed before system startup.
I NSTALLATION AN D ADJUSTM ENTIn following these installation instructions note that theadjustment is accomplished by rotating the turnbuckle, rodcoupling or load column provided with the spring unit.
Firmly secure the spring unit to the structure. Attach theappropriate rod and/or pipe attachment. Cut the bandingholding the Load Presets or Travel Stops. Remove the
down limit stops, if applicable. To remove the LoadPresets, the spring load must be increased slightly by use ofthe adjustment means provided. After the Load Presets orTravel Stops have been removed, readjust the spring unitback to the exact Cold Load setting.
Prior to startup, be sure all of the spring units have hadtheir Load Presets or Travel Stops removed, and have beenadjusted to their Cold Load setting.
After starlup and when the piping system has stabilizedthermally, the Lpad Indicator on the unit should be at theHot Load (Operating) setting. If it is not, the spring shouldbe adjusted to the Hot Load setting. No further adjustmentshould be needed.

SIZE AND SERIES SELECTION PROCEDURE
The key criteria in selecting the size and series of a VariableSpring suppofi is a factor known as Variability. This is a cal-culation of the percentage change in the supporling force ofa variable spring between the Hot (Operating Condition) andthe Cold (Installed Condition). The formula is shown below.For practical purposes this percentage relates to the amountof load the spring transfers back into the piping system priorto operation. The lower the Variability the lower the effecton the system while in the Cold position. Since the Hot Loadis the actual Operating Load of the piping, loading due toVariability is not a factor.
The Spring Rate is the amount of load required to deflect a
spring coil over a given distance and is expressed in poundsper inch (Newtons per millimeter).
The Movement is the amount the piping system changes dueto thermal growth when moving from the Cold to Hot position.
Variability = Movement x Spring RateHot Load
% Variability = Variability x 100
The Cold Load is calculated by adding (for UP movement)or subtracting (for DOWN movement) the product of SpringRate times the Movement to or from the Hot Load.
If an allowable Variability is not specified, good practicewould be to :use 257o as specified by MSS-SP-5S.
TO SELECT THE PROPER SIZE AND SERIES
1. Find the Hot Load in one of Spring Size columns on theappropriate SIZE AND SERIES SELECTION CHARTfound on page 5, 6, or J.
2. Calculate the maximum allowable Spring Rate from theformula;
Spring Rate = Variability x Hot LoadMovement
3. Stay in the column and choose the Travel Series with a
Spring Rate equal to or less than the value calculated.
4. Calculate the Cold Load and check that both the HotLoad and Cold Load fall within the Working Range of the
Travel Series selected.
5. If your requirements are not met, move to an adjacentSpring Size column and recalculate again using the aboveprocedure.
If the Movement or loading requirements cannot be satis-fied, select a Travel Series with a greater Working Rangeand recalculate.
If any combination of Load, Movement and/or Variabilitycannot achieve the desired results the use of a ConstantSupport should be considered.
Variability = 20Vo Maximum
SOLUTION:
1. Calculate Spring Rate.
0.20 x 307 lbs. =0.50 inches
0.20 x '1366 N =13mm
EXAMPLE:Select a Variable SpringHot Load = 307 lbs.Movement = V2" tJp
for the following conditions:or 1366 N or 139 Kgor 13 mm or 13 mm207a max. 207o max.
122.8 lbs. per inch, or
21 N/mm, or
0.20 x 139 Kg = 2:4 Kg/mm13mm
2. Find the Spring Size column on the SIZE AND SERIESSELECTION CHART where the Hot Load is 307lbs.,or 1366 N or 139 Kg.
(A Size 5, Series 920 fits the criteria).
3. Calculate the Cold Load.
63 lbs. per inch x 0.50 inches
11 Npermmx13mm
1.12Kgpermmx13mm = 15Kg
Since the Movement is UP, add the above load change tothe Hot Load.
307 lbs. + 32 lbs. = 339 lbs. Cold Load, or
1366N + 143N = 1509 N Cold Load, or
139 Kg + 15 Kg = 154 Kg Cold Load
4. Now check to see if the Hot Load and Cold Load fit inthe Working Range of a Size 5 Series 920. If so, youhave selected the proper unit.
If you are unable to find the proper size and series ofyour application, please call us.

VARIABLE SPRING SUPPORTS
OUT CALCULATION
Type C
Type G
For Spring Types A, B, C, and G, the Rod Takeout can be calculated by adding the spring deflection ofthe loadindicator at the cold load setting (found on pages 5-7) to the "E" dimension and then subtracting 3"to compensate for one half of the turnbuckle gap used for adjustment.
Example: A Figure 9208 Size f4, with an lnstalled Load of 4000 lbs. Has a Rod Take out of (1-9"+1.5"-3") = 17.5"
Type D
This spring type does not require any adjustment to its' "E" dimension.
Type E
Hanger rod length to be determined by the customer.
Note: Please confirm that sufficient thread length is available
on the rod for field adjustment for all spring types.

CALCULATING OF PIPINIG INSULATION WEIGHT
The weight per foot of insulation is calculated by using the weightfactor "X" from the table below and multiplying by the insulationdensity (lbs/cu-ft).
EXAMPLE: A 16" pipe wrth 3%" of insulation is lbund to have a
weight factor of 1.49 (from table below). With an insulation density of11 lb/cu-ft, the calculation for insulation weight is 1.49 x 17 = 16.39

General Formula: For pipe sizes not shown in the table above (special
O.D. pipe, etc.), use the lbllowing formula to determine the insulation weight:
Insulation Weight: (lb/f0 = 0.0218 x I x T x (T + D)
Where: I = Insulation density (lb/cu-ft)T = Insulation thickress 1inches.1
D= Outside diameter of pipe (inches)
