Type: Variable Spring Supports w/ Rollers
Size: Springs: 11.1/16″ H | Rollers: 24″ -36″ Dia.
Design: 700-15,970 lb. Loads | 650°F Temp.
Material: HDG Carbon Steel | Cast-iron
Testing: Standard Load Testing & Q.C. Inspection

PT&P designed and fabricated custom F-type variable springs with rollers for a fabrication company in Texas. The variables are fabricated from carbon steel with a hot-dipped galvanized coating. They include a cast-iron roller bolted to the top of the load flange. These variables are 11-1/16” in height with weights up to 86 lb. The roller stands are designed for pipe sizes ranging from 24″ to 36″ in diameter. They are designed for an operating temperature of 650°F and are capable of supporting loads that range from 700 lb. to 15,970 lb. There are special features like the load flange, bottom flange, and the springs that are loaded with a preset load. Standard spring test and Q.C. inspections were conducted prior to shipment.

Variable Spring Support with Bronzphite® Slide Plates Designed for a Facility in Canada

PT&P manufactured these F-type variable spring supports for a facility in Canada. The springs are fabricated from A36 carbon steel with a hot-dipped galvanized finish. The variables installed heights range from 11″ to 15″ and are designed for operating conditions up to 4,000 lb. Bronzphite® is best suited for high loads, low velocity applications and where the use of oil or grease is undesirable or unfeasible. The bronze plate acts as the bearing surface, withstanding heavy loads, while the graphite inserts provide a solid, oil-free lubricant. 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.

F-Type Variable Spring Supports Designed for an LNG Facility

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.
