In-house certified technicians and a qualitative specification-assurance process that is second to none back every shipment leaving our Houston facility.
Across southeastern Pennsylvania, heavy-plate and specialty steel keeps demand high for alloys that perform under pressure, heat, and corrosion. That is where Alloy 20 (Carpenter 20® (Alloy 20)) earns its place, and where P.A. Inc. supplies Coatesville with certified pipe, fittings, and flanges.
What makes Alloy 20 the right specification is straightforward: exceptional resistance to hot sulfuric acid across a wide concentration range and resistance to pitting, crevice corrosion and chloride stress-corrosion cracking. For Coatesville operators, that translates into longer service life, fewer unplanned outages, and predictable behavior during the thermal and chemical cycling their processes put material through.
Our Coatesville customers put Alloy 20 to work across the demanding end of process service: sulfuric acid production and handling, pharmaceutical and plastics processing, pickling tanks and acid mixing equipment, and food, dye and synthetic-material production. Because P.A. Inc. fabricates locally in Houston, we can turn butt-weld fittings, flanges, and custom spools to the exact schedule and end-prep a Coatesville turnaround crew needs — and deliver to Downingtown, Parkesburg, and Thorndale and the surrounding region without the freight time of pulling material from out of state.
For Coatesville buyers working to tight ASME and API documentation standards, paperwork matters as much as metal. That’s why every order of Alloy 20 ships with complete, original Mill Test Reports and full heat traceability — backed by a service center that answers the phone around the clock.
