2 Page info@aaatech.com EQUAL SPRING GENERAL INFORMATION TRAVEL STOPS Travel stop are furnished only upon request. Full travel stops limiting both upward and downward movement may be supplied; or upward or downward travel stops individually may be supplied. Full travel stops effectively convert the hanger assembly to a rigid support until the stops are removed. Upward travel stops restrict upward movement beyond a customer specified point on the travel scale. Downward travel stops restrict downward movement beyond a customer specified point on the travel scale and are frequently employed during erection and hydrostatic testing. A red tag is attached to each travel stop to emphasize the need to remove the travel stops before the piping system is placed in service. LIFTING LUGS Upon customer request, lifting lugs may be welded to the hanger casings of designated spring hanger in order to provide a sure means of attachment for lifting during installation. Contact AAA Technology for details. FIELD ADJUSTMENT Once the piping and the spring hangers are installed and hydrotested, the preset bar should be removed from the spring hanger. The compression plate on top of the spring coil should be at the installed load mark on the spring hanger load scale. If the bottom of the compression plate is not at the installed load mark on the spring hanger load scale, then the load should be adjusted so that it is. After the piping system is placed in service, the compression plate should indicate that the load being carried is the designated operating load. If the bottom of the compression plate is not at the operating load mark on the spring hanger load scale, then the load should be adjusted so that the bottom of the compression plate is at the operating load position. To adjust the load carried by the spring hangers types "A", "B", "C", "E", and "G", turn the turnbuckle clockwise or counter clockwise, as necessary, until the bottom of the compression plate lines up with the proper travel tag on the travel scale. For hanger type "D", loosen the lock nut and adjustment the heavy hex nut on top of the pipe stem which sits on the compression plate until the bottom of the compression plate lines up with the proper travel tag on the travel scale. For hanger type "F", turn the load column clockwise or counterclockwise, as necessary, until the bottom of the compression plate lines up with the proper travel tag on the travel scale. DETERMINING THE TYPE The type of variable spring hanger to be used for specific applications depends upon controlling factors such as the amount of head room available, whether the pipe is to be supported from above or from below, the configuration of the structural steel from which the pipe is to be supported, etc. Review the characteristics of the seven standard variable hanger types shown on the next page and select the type that best fits your requirements.

3 AAA Technology & Specialties Co., Inc. Page 2 DETERMINING THE AND SERIES TO USE The load to be carried in the operating condition and the installed to operating deflection must be accurately calculated by a stress engineer. This data can be determined analytically by computer analysis or estimated by manual calculations. To determine the optimum load to be carried by the spring hanger in the operating position, calculate the weight of the piping system in the " as installed condition" which is carried by a rigid support placed where the spring hanger is to be located. The calculation should include 1.) the weight of the pipe, valves and fittings, 2.) the weight of the contents and insulation, and 3.) the weight of the hanger hardware below the spring hanger casing. Note: For a type G spring hanger, the load to be carried by the hanger should also include the catalog weight of the hanger unit itself. Once the load to be carried is determined, the installed to operating deflection can be calculated by performing an operating case analysis with the optimum load considered as a constant acting upward force. The analysis results will reflect the piping system deflection from the installed position to the operating position. "EQUAL" spring hangers are designed and manufactured for the following ranges of movement: 1.25" (Fig. E-82), 2.5" (Fig, E- 268), 5.0" (Fig. E-98) 7.5" (Fig. E-100) and 10 (Fig. E-110). Knowing the ranges of movements accepted by "EQUAL" hangers, the operating load and the installed to operating deflection, you are now ready to select the spring that best fits your requirements. Turn to the " Hanger Size and Series Chart" which can be found on page 21 (Imperial units), on page 22 (metric kilograms/mm) and on page 23 (metric Newtons/mm). Moving from left to right between the upper and lower boundaries of the Working Range, find the first occurrence of your operating load. If the movement from the installed position to the operating position is downwards, move upwards from the operating position on the chart by the amount of the movement to find the installed load. If the movement from the installed position to the operating position is upwards, move downwards from the operating position on the chart by the amount of the movement to find the installed load. In the event that the travel places you outside of the Working Range, you have the option to try using the next larger size spring or to move up to the next series of spring. In other words, you can move from an E-82 to an E-268 spring or from an E-268 spring to an E-98 spring, etc. Please note that the MSS Standard also states that the maximum load variation from the installed position to the operating position is 25%. That means that the maximum movement for a Fig. E-82 spring hanger is approximately 3/4 (19 mm), for a Fig. E-268 spring hanger is approximately 1 1/2 (38 mm), for a Fig. E-98 spring hanger is approximately 3 (76 mm), for a Fig. E -100 spring hanger is approximately 4 1/2 (114 mm) and for a Fig. E-110 spring hanger is approximately 6 (152 mm), Please note that for a variable spring hanger to be acceptable the operating load and the installed position must be within the Working Range on the chart. If the load variation for the piping system application is found to not be acceptable using a variable spring hanger, then you should consider the use of a constant effort spring hanger. ORDERING TYPE "A", "B", "C", D and "E" Specify: Figure Number, Size, Type, Operating load, Installed position to Operating position Deflection including direction of movement, Customer's Tag Number, the Finish Desired and Travel Stops, if desired.

5 AAA Technology & Specialties Co., Inc. Page 4 APPLICATION DATA TYPE A Used where ample headroom is available and where it is desired to locate the spring hanger at a specific elevation. Structural attachment point is at a point above the top of the hanger. TYPE B Used where headroom is limited. Head attachment is a single lug. Typically used in conjunction with Fig. 515 beam bracket, a Fig. 415 steel clevis or back to back angles.

6 Page info@aaatech.com TYPE C Used where headroom is limited. Head attachment is side-by-side lugs. Typically used in conjunction with a Fig. 418 weldless eye nut or a Fig. 521 structural welding lug. TYPE D Used where the spring hanger is mounted on top of a pair of back-to-back channels. Provides for adjustment of the load by turning the nut at the top of rod shown above. TYPE E Used where the spring hanger is mounted on top of a pair of back-to-back channels. Provides for adjustments of the load from below the supporting channels by turning the turnbuckle.

7 AAA Technology & Specialties Co., Inc. Page 6 TYPE F Used where the spring hanger must be placed under the piping to provide support from the floor or a structural member. Typically supplied with a load flange but can also be supplied with a roller. TYPE G Used where head room is insufficient to accommodate the spring hanger and the necessary associated hardware. Also used where an interference exists directly above the piping system at the support location. Note if the piping system being supported is not centered between the spring hangers each hanger will then carry its proportional load and will be different in magnitude.
