Custom Constant Spring Supports for Heat Recovery Steam Generators

PT&P custom-designed constant spring support assemblies for heat recovery steam generator at a combined-cycle power plant. These power plants utilize gas turbines, steam turbines, heat exchangers along with other components to make use of “exhaust waste” for a more efficient system. These 200-F Type constants were fabricated from A36 carbon steel and include a hot-dipped galvanized finish. The spring coils are formed from alloy steel and are neoprene coated. They are designed for an operating load for up to 886 lb., and up to 6″ of maximum travel. They are placed beneath the unit being supported and allow for movement in the vertical direction (up or down). The dimensions are 13″ W x 31″ L x 18-1/2″ H. Standard load and travel tests along with a quality control inspection were conducted prior to shipment.
