PT&P manufactured F-type variable spring supports for an LNG facility in Colorado. The variables installed heights range from 10-5/8″ to 21-1/16″. The F-Type pipe hanger assembly is used to support the pipe from below and are typically mounted to concrete pads via anchor bolts or welded to structural steel. The various springs shown are designed for operating conditions ranging from loads of 633 lb. to 6510 lb. As with all of our variable supports, these were quality checked with a 100% spring coil deflection test and a load cell calibration to set the assembly at the prescribed installed load.
