PT&P manufactured F-type variable spring supports for a chemical processing plant in Texas. The variables are designed with an internal guide and for a movement of 0.09″. They are designed for a 5,350 lb. cold load and 5,450 lb. hot load. Because these springs had to be capable of withstanding a hydro-test in excess of 33,000 lb. (which substantially exceeded the standard maximum hydro-test of 18,000 lb.), special collars were used in conjunction with the standard travel stops. These collars are designed to absorb the large hydro load by relying on the high strength characteristics of the load flange and housing components of the assembly while essentially bypassing the threaded internal components.
