In-house certified technicians and a qualitative specification-assurance process that is second to none back every shipment leaving our Houston facility.
For the a dense industrial and pipeline network, material selection is not a place to cut corners. Alloy 20 (UNS N08020) delivers the performance that Chicago’s refining and heavy manufacturing operators depend on, and P.A. Inc. keeps it on the shelf — ready for fast delivery across Illinois.
The reason Chicago engineers keep coming back to Alloy 20 comes down to its metallurgy — exceptional resistance to hot sulfuric acid across a wide concentration range and resistance to pitting, crevice corrosion and chloride stress-corrosion cracking. In demanding refining and heavy manufacturing service, those properties are the difference between a component that lasts a campaign and one that fails early.
Our Chicago 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 Chicago turnaround crew needs — and deliver to Joliet, Lemont, and Hammond and the surrounding region without the freight time of pulling material from out of state.
For Chicago 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.
If your Chicago operation needs Alloy 20 Pipe & Fittings — whether it’s a single spool for an emergency repair or a full material package for a planned outage — call P.A. Inc. at 713-570-4900 for pricing, availability, and certified documentation.
