A total of 232 variable spring supports were custom designed for a natural gas processing and separation plant. This project included various spring sizes from PTP-1 30 C-type to PTP-4 160 F-type assemblies. The variables are fabricated from carbon steel, galvanized and coated with a special 3-coat paint system to protect against corrosive byproducts such as sulphur. The F-types include 304 stainless steel and PTFE, 25% glass filled slide plate assemblies.
