PT&P designed and fabricated F-type variables for an oil refinery in California. The variable springs are designed for an operating load of 49,771 lb. and an installed load of 43,000 lb. Two coils are used in tandem to achieve a vertical movement of 1-5/8″ downward. The variables are fabricated from hot-dipped galvanized carbon steel and are customized with an extended load column to reach an installed height of 67-1/2″. The variables for this project are the largest standard double springs offered; however, PT&P can customize to any load specification. Standard load testing was performed prior to shipment.
