Custom Designed 30 Foot long Rod Hanger Assemblies for a Power Plant in North Carolina

Type: Rod Hanger Assemblies
Size: 3-1/2” Diameter | 30′ Long
Material: A36 Carbon Steel  | SA-182 F1 | A563 Gr. C | Red Oxide
Design: Custom Designed Length & Diameter

PT&P custom designed and manufactured sixty rod hanger assemblies for a power plant in North Carolina. The rod diameter is 3 ½” and 30 feet long and utilizes Fig. 95 clevises. The rod material is A36 carbon steel, the clevises from SA -182 F1, and hex nuts from A563 Gr. C. The assemblies were also painted with red oxide primer to protect against corrosion. The rod hangers had to be custom designed because the length and diameter required was not readily available in the marketplace.

29 Specially Designed High-Temperature Supports for a Power Plant in Arizona

Type: High Temperature Pipe Suports (Hot Shoes)
Size: 10” NPS x 6” Hot Insulation x 12” Long
Material: Carbon Steel with HDG finish | Casi & High Density Inserts
Design: 1200°F | 15,000 lb. Vertical | 6,245 lb. Axial

These pre-insulated high-temperature pipe supports were designed and fabricated for a 10” diameter high-temperature pipeline at a power plant in Arizona. The supports are fabricated from carbon steel with HDG finish and include casi & high-density inserts. They are designed to guide pipes that may reach up to 1200°F, high loads of up to 15,000 lb. vertical and 6,245 lb. axial. There were twenty-nine total “hot shoes” ranging in different designs. The “grooves” in the insulation are for steam tracing. Steam tracing is heat tracing performed by circulating steam around process pipes to heat them. The shoe assemblies are comprised of the four guides on the shoe and adjustable stops. They are designed to account for lateral, vertical, and axial movement. Dimensions for the supports pictured are 10” NPS x 6” thick insulation x 12” long base. Standard tests and Q.C. inspections were performed before shipping.
