San Angelo sits at the center of Concho Valley energy and manufacturing, and operations here demand piping materials that hold up where ordinary steels fail. Alloy 20 (Carpenter 20® (Alloy 20), UNS N08020) was engineered for exactly that duty, and P.A. Inc. stocks it in pipe, fittings, and flanges ready to ship into the San Angelo area.
San Angelo process and maintenance teams choose Alloy 20 when ordinary stainless grades fall short. With exceptional resistance to hot sulfuric acid across a wide concentration range, plus resistance to pitting, crevice corrosion and chloride stress-corrosion cracking, Alloy 20 stands up to the aggressive environments common in local oil and gas operations.
Our San Angelo 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 San Angelo turnaround crew needs — and deliver to Goodfellow AFB, Wall, and Grape Creek and the surrounding region without the freight time of pulling material from out of state.
Every length of Alloy 20 leaving our facility ships with a full set of original Mill Test Reports, traceable to both the manufacturer and the heat of origin — the documentation San Angelo plants operating under ASME and API requirements can’t do without. And with our team answering the phone 24 hours a day, a San Angelo turnaround that runs long always has someone to call.
