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.

Variable Spring Supports Designed For A Highly Corrosive Environment In Peru

Type: Variable Spring Supports w/ PTFE Slide Plates
Size: PTP-4 | 9.5″ – 11.5″ Height
Design: 1/8″ Upward & 3/16″ Downward Travel
Material: HDG Carbon Steel | Gloss Aliphatic Polyurethane Topcoat | PTFE, 25% Glass Filled Slide Plates
Testing: Standard Load Testing & Q.C. Inspection

Piping Technology & Products, Inc. recently designed and fabricated F-type variable spring supports for a plant in Peru. The variables are fabricated from carbon steel, hot-dipped galvanized and a gloss aliphatic polyurethane topcoat was applied for corrosion protection. PTFE, 25% glass filled, slide plates are bonded to the top of the load flange to reduce the friction caused by lateral movement. The variables range from 9.5″ to 11.5″ in height and are designed for a travel range of 1/8″ upward to 3/16″ downward. To ensure quality, standard load testing was performed prior to shipping.
