Variable Spring HangersVariable Spring Hanger and Structural Steel Assembly

These variable spring hangers were designed for a 10″ pipe line in a solar electric generating system. All assemblies were fabricated from A-36 carbon steel with a hot-dipped galvanize finish. The picture on the left shows a structural steel assembly supporting a PTP-1 variable spring and a Fig.80 heavy 3-bolt clamp designed for a 3,789 lb. load. The picture on the right shows two PTP-2 variable spring hangers welded to a structural steel beam designed for a 675 lb. load. Each pipe hanger assembly went through standard load and travel testing prior to shipping.

200 E-Type Horizontal Constant Spring Supports for a Fired Heater Radiant Manifold

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.

Variable Spring Supports with Permanent Upward Travel Stops

October 2, 2012

Five total assemblies of custom designed variable spring supports were made for an oil refinery in the United Arab Emirates. These springs required a permanent upward travel stop. The spring cans were supplied with PTFE and polished stainless steel slide plates attached to carbon steel load flange. All materials used were domestic (from the U.S.). The springs were tested for lateral loads. The spring coils were stress tested and can withstand temperatures of 176°F (80°C), with a downward movement of 30mm – 45mm.
