VARIABLE SPRING SUPPORTS INTRODUCTION The Variable Support is a spring loaded device used for the support of piping and equipment where normal vertical movement is anticipated. Variable Supports are manufactured in five different Travel Series which allow up to ten inches of movement and twenty-five different sizes allowing up to 50,000 pounds of load. Seven different mounting Types allow the user the widest selection of configurations to accommodate practically every hanger design.

RECOMMENDED SERVICE Normally for support of piping systems where thermal changes cause the system dimensions and position to change, and where load transfer to equipment is not a problem. Maximum recommended variation from the operating load is 25%. A constant support should be used when Variability exceeds 25%. Also used for support of equipment and ductwork to customer specifications.

SPECIFICATIONS All spring units are designed to meet the requirements of: • ASME Code for Pressure Piping, ASME B31.1, B31.3 • Manufacturers Standardization Society (MSS), SP-58, and SP-69 • Federal Specification A-A-1192-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. All welding is done to the strict requirements of ASME Section IX. • The Piston Plate serves as a centering device and guide maintaining coil concentricity under normal operating 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

•

purposes. The strength of the 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 normal operating 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 normal per customer request. Lifting Lugs – are available on larger sizes to facilitate erection and installation. Hot-dip Galvanized Finish – available for protection against weather and corrosive conditions. The unit is galvanized to ASTM A-153 except the spring coil which is epoxy powder coated to assure protection to the coil as it flexes. The load column of the F Type spring is electrogalvanized. Maximum ambient temperature for the epoxy powdered coating is 350° F (177° C). Epoxy Paint Finish – available for protection against weather and corrosive 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 completely of stainless steel except the spring coil which can be epoxy powder coated for economy.

DETERMINING THE TRAVEL SERIES In choosing the proper Variable Spring Travel Series it must first be determined that the calculated movement will fall 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 11⁄4" through 10".

SIZE AND SERIES SELECTION PROCEDURE The size of the Variable Spring support 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.

DETERMINING THE TYPE The type of Variable Spring support 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 seven (7) standard types available for each Travel Series; they are: • Type A – Is attached to the supporting member by a vertical 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 structure to permit connecting with a bolt or pin to a clevis or welded beam attachment.

VARIABLE SPRING SUPPORTS • Type C – Also designed for limited headroom applications. The unit has two lugs welded to the top of the casing to permit connecting with a bolt or pin through a single lug attachment to the structure. • Type D – Designed for use where the variable spring is positioned above the supporting structure and spring adjustment is made from the top. • Type E – Also designed for use where the variable spring is positioned above the supporting structure, but where the spring adjustment must be below the structure on which the case is supported. • Type F – Designed to support piping from below. Used to support pipe from the floor or where support from overhead is not practical. • Type G – For use where headroom is limited or an obstruction prohibits the use of a single rod type Variable Spring.

LOAD PRESET BAR AND TRAVEL STOP The Load Preset Bars are installed at the factory at the Cold Load setting of the unit. The Travel Stops, which are optional and will be provided only if ordered, include both the Load Preset Bars to preset the unit at the Cold Load setting and more importantly a down limit stop which locks the unit at that position. This locking effect results in the unit functioning as a rigid hanger during erection, hydrostatic testing, chemical cleaning or other condition which may cause the unit to exceed its load rating. The Travel Stops are designed for twice the maximum working load of the unit and are installed at the factory with a “Caution” tag which calls attention to the fact that they must be removed before system startup.

INSTALLATION AND ADJUSTMENT In following these installation instructions note that the adjustment is accomplished by rotating the turnbuckle, rod coupling or load column provided with the spring unit. Firmly secure the spring unit to the structure. Attach the appropriate rod and/or pipe attachment. Cut the banding holding the Load Presets or Travel Stops. Remove the

down limit stops, if applicable. To remove the Load Presets, the spring load must be increased slightly by use of the adjustment means provided. After the Load Presets or Travel Stops have been removed, readjust the spring unit back to the exact Cold Load setting. Prior to startup, be sure all of the spring units have had their Load Presets or Travel Stops removed, and have been adjusted to their Cold Load setting. After startup and when the piping system has stabilized thermally, the Load Indicator on the unit should be at the Hot Load (Operating) setting. If it is not, the spring should be adjusted to the Hot Load setting. No further adjustment should be needed.

ORDERING INSTRUCTIONS: When ordering a Variable Spring Support please specify for each unit: 1. Travel Series: 910, 920, 940, 960, or 980 2. Spring Type: A, B, C, D, E, F or G 3.

VARIABLE SPRING SUPPORTS SIZE AND SERIES SELECTION PROCEDURE The key criteria in selecting the size and series of a Variable Spring support is a factor known as Variability. This is a calculation of the percentage change in the supporting force of a variable spring between the Hot (Operating Condition) and the Cold (Installed Condition). The formula is shown below. For practical purposes this percentage relates to the amount of load the spring transfers back into the piping system prior to operation. The lower the Variability the lower the effect on the system while in the Cold position. Since the Hot Load is the actual Operating Load of the piping, loading due to Variability 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 pounds per inch (Newtons per millimeter). The Movement is the amount the piping system changes due to thermal growth when moving from the Cold to Hot position. Variability = Movement x Spring Rate Hot Load % Variability = Variability x 100 The Cold Load is calculated by adding (for UP movement) or subtracting (for DOWN movement) the product of Spring Rate times the Movement to or from the Hot Load. If an allowable Variability is not specified, good practice would be to use 25% as specified by MSS-SP-58. TO SELECT THE PROPER SIZE AND SERIES 1. Find the Hot Load in one of Spring Size columns on the appropriate SIZE AND SERIES SELECTION CHART found on page 5, 6, or 7. 2. Calculate the maximum allowable Spring Rate from the formula: Spring Rate = Variability x Hot Load Movement 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 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 satisfied, 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.

EXAMPLE: Select a Variable Spring for the following conditions: Hot Load = 307 lbs. or 1366 N or 139 Kg Movement = 1â &#x201E;2" up or 13 mm or 13 mm Variability = 20% Maximum 20% max. 20% max. SOLUTION: 1. Calculate Spring Rate. 0.20 x 307 lbs. = 122.8 lbs. per inch, or 0.50 inches 0.20 x 1366 N = 21 N/mm, or 13mm 0.20 x 139 Kg = 2.14 Kg/mm 13mm 2. Find the Spring Size column on the SIZE AND SERIES SELECTION CHART where the Hot Load is 307 lbs., 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

= 32 lbs., or

11 N per mm x 13 mm

= 143 N, or

1.12 Kg per mm x 13 mm

= 15 Kg

Since the Movement is UP, add the above load change to the Hot Load. 307 lbs. + 32 lbs. = 339 lbs. Cold Load, or 1366 N + 143 N

= 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 in the Working Range of a Size 5 Series 920. If so, you have selected the proper unit. If you are unable to find the proper size and series of your application, please call us.

VARIABLE SPRING SUPPORTS

VARIABLE SPRING ROD TAKE OUT CALCULATION Type A

Type B

Type C

Type G

For Spring Types A, B, C, and G, the Rod Takeout can be calculated by adding the spring deflection of the load indicator at the cold load setting (found on pages 5 7) to the "E" dimension and then subtracting 3" indicator 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 920B Size 14, with an Installed Load of 4000 lbs. Has a Rod Take out of (19"+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. 45

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
