In-house certified technicians and a qualitative specification-assurance process that is second to none back every shipment leaving our Houston facility.
Across the Louisiana chemical corridor, River Road industrial complexes keeps demand high for alloys that perform under pressure, heat, and corrosion. That is where 304H Stainless (304H Stainless Steel) earns its place, and where P.A. Inc. supplies Geismar with certified pipe, fittings, and flanges.
The reason Geismar engineers keep coming back to 304H Stainless comes down to its metallurgy — higher creep and rupture strength than standard 304 above 1000°f (540°c) and good oxidation resistance in intermittent and continuous high-temperature service. In demanding chemical service, those properties are the difference between a component that lasts a campaign and one that fails early.
Our Geismar customers put 304H Stainless to work across the demanding end of process service: high-temperature refinery and petrochemical piping, superheater and reheater tubing, boiler and pressure-vessel components, and furnace and process headers. 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 Geismar turnaround crew needs — and deliver to Gonzales, Sorrento, and Prairieville and the surrounding region without the freight time of pulling material from out of state.
Every length of 304H Stainless 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 Geismar plants operating under ASME and API requirements can’t do without. And with our team answering the phone 24 hours a day, a Geismar turnaround that runs long always has someone to call.
If your Geismar operation needs 304H Stainless 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.
