This big ton spring assembly is designed for a local area refinery, and is fabricated from carbon steel components with a painted finish. The top of the load flange has three PTFE, 25% glass filled slide plates. The base is 96″ x 18″ and the installed height is 24″. This big ton spring will be utilized to support heavy (in excess of 76,000 lb.) loads where a standard variable spring would be undersized. The big ton spring design includes an array of parallel coils within one frame to produce large load carrying capacity while maintaining the same spring rate. The assembly is designed to withstand an operating load of 76,800 lb. and has a downward travel of 0.894″.

Prior to fabrication, each of the coils were individually tested to insure correct spring rate and load capacity. After fabrication, the entire assembly was tested throughout the entire load and travel range.

The top sheet of graphite measures 1/2″ x 11 1/2″ x 115 1/2″. This particular design also includes a bottom sheet of graphite with the same dimensions, but only 1/4″ thick. Each individual graphite sheet is bonded to a hot dipped galvanized backing plate with a 1/2″ lip all around for full welding. In an application where the pipe has large amount of movement due to thermal expansion, slide plates can be utilized to eliminate friction between the pipe support and the supporting member. Graphite is used when the slide plate must function at high temperatures. These particular graphite slide plates are designed for 1000ºF.
