U-Type Constant Spring Supports Designed for an LNG Plant in Canada

PT&P designed U-Type constant spring supports for an LNG plant in Canada. These are horizontal constants designed to support piping from below where the base plate is bolted directly to the top of the steel or the foundation using anchor bolts. These specific constant springs are designed to support an operating load of 67,420 lb. with 6” of total upwards travel. The constants are fabricated from galvanized carbon steel for protection against corrosion. Standard load and travel testing were completed to ensure the quality and performance of these constants.
