Bellmouth Reducers & Custom Pipe Spools Designed for an Ammonia Plant

Type: Bellmouth Reducers, Ring Flanges, Pipe Spool Elbows
Size: 36” NPS | Opened to 48″ NPS
Material: Carbon Steel  | 304 Stainless Steel
Design: 150°F | 150 PSI Operating Pressure

PT&P designed and manufactured bellmouth reducers, ring flanges and custom pipe spool elbows for an Ammonia Plant in Texas. Bellmouth reducers are a single piece component used to transition a large outside diameter into a smaller outside diameter piping. These reducers are used in the cooling process; the shape allows for drawing in maximum amounts of air while preventing loss. The bellmouths are fabricated from carbon steel and 304 stainless steel. They are designed for operating temperatures of 150°F with an operating pressure of 150 PSI. Dimensions are 36” NPS opened to 48” bellmouth. Tests that were performed are spot x-ray, visual and dimensional, PMI-alloys and stainless steel.

Sway Strut & 3-Bolt Pipe Clamp Assemblies Designed for a Power Plant in California

Type: Sway Strut & 3-Bolt Pipe Clamp Assembly
Size: 30″ NPS | 44-1/8″ CC | 4″ Adjustment
Material: Carbon Steel | 304 Stainless Steel
Design: Restrain Tensile/Compressive Force in 1 Direction
Permit Movement in Other Directions

PT&P fabricated and designed sway strut and 3-bolt pipe clamp assemblies for a power plant in California. The assemblies are manufactured from carbon steel with 304 stainless steel load pins. They are designed for a 30” diameter pipe. The sway strut has a cc of 44–1/8” and 4” adjustment. The sway struts are designed to restrain either tensile or compressive force in one direction while providing for movement due to thermal expansion or contraction in other directions.

Pre-Insulated Pipe Supports Custom Designed with 6” of High Density Insulation for a High Temperature Pipeline

August 5, 2019

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.
