These 200 E-Type horizontal constant spring supports are fabricated from A-36 carbon steel with a hot-dipped galvanize finish. The pins made for constants operation are A-322-4140 high strength carbon steel. The constants range in size from 22-3/4″ to 26-1/4″ heights, 60″ to 90″ lengths, 18″ width, and 19-1/2″ to 23-1/2″ in coil housing diameters. They are designed for 23,160 lb. to 33,700 lb. loads and 6-1/2″ to 14″ of total travel. A total of sixteen assemblies were custom designed for a fired heater radiant manifold. Each pipe hanger assembly went through standard load and travel testing prior to shipping.
