Personnel Protection Shields Designed for a Power Plant

Type: Personnel Protection Shields
Size: 8″ Dia. | Up to 36″ Lengths
Material: Galvanized Carbon Steel
Design: 1050°F Operating Temperature

PT&P custom designed these personnel protection shields for a power plant in Wyoming. The personnel protection shields are used when insulating the line is not necessary, but operating temperatures require safeguarding personnel from coming into contact with the pipe. These shields are designed for an 8” diameter pipe operating at 1050°F. They are fabricated from carbon steel and range in lengths up to 36”.

Bellmouth Reducers & Custom Pipe Spools Designed for an Ammonia Plant

 

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.

Custom Manifolds Designed for a Polyethylene Facility

 

Custom Manifolds with Globe and Gate Valves Designed for a Polyethylene Facility

Type: Custom Manifolds with Globe and Gate Valves
Size: 72” Height | 1″ x 1-1/2″ | 1″ x 2”
Material: SA-105 | SA-106B | SA-36
Testing: 100% Dimensional | Inspection Q.C. Inspection
NDE(RT,PT) Hardness | Hydro-test @ 430 PSIG

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.
