PT&P designed and fabricated a U-Type constant spring support , with PTFE and a 25% glass-filled side plate for a Polypropylene Plant in Texas. The constant is fabricated from carbon steel and hot-dipped galvanized for extra protection against corrosion. The vertical movement is 1.5" total upward travel and is capable of supporting a load of 10,350 lbs. throughout its range of movement. The constant underwent standard load testing prior to shipment.
Along with chemical plants, constant spring supports are utilized in refineries, power plants, and heat recovery steam generators (HRSG). The design of the constant spring support replaced a system of pipe support called a "counterweight" design still used in some facilities today. The counter-weight system utilized pipe clamps or lugs (attached or welded to the pipe), cables, pulleys, and a set of weights. Just like the old-fashioned brass weighing scales, weights were added to one end of the pulley system until an equilibrium was reached. The counterweight design needed a large amount of space with which to operate. Constant spring hangers replaced this system because they require much less space in order to function (similar to some designs we stand on to weigh ourselves). No matter the application, our team of experienced engineers and designers can help to resolve your pipe support needs.
