PT&P supplied 41 custom manifolds with globe and gate valves to a manufacturing complex in La Porte, Texas. The manifolds were installed in a hot water tracing supply and return system at a high-density polyethylene (HDPE) facility. Each manifold was welded to the exact specifications listed on the production drawing developed. The body was fabricated from 2” and 1” seamless XS pipe. The ports were FNPT and flange connection for field installation. All Manifolds were supplied with welded brackets and vertical support stands. The material used for the valves and flanges were SA-105, pipe SA -106B, and the supports are manufactured from SA-36. The overall height is 72″, and the dimensions are 1″ branches x 1-1/2″ run line and 1″ branches x 2″ run line. Inspection and Q.C. tests were performed by an internal and TPI team including 100 % dimensional inspection, NDE(RT,PT), hardness, and hydro-test at 430 PSIG.

September 9, 2019
| 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.

August 26, 2019
| 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.

August 5, 2019
| 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.
