In-house certified technicians and a qualitative specification-assurance process that is second to none back every shipment leaving our Houston facility.
Across southwest Louisiana, large-scale olefins expansions 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 Lake Charles with certified pipe, fittings, and flanges.
What makes 304H Stainless the right specification is straightforward: higher creep and rupture strength than standard 304 above 1000°f (540°c) and good oxidation resistance in intermittent and continuous high-temperature service. For Lake Charles 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 Lake Charles 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 Lake Charles turnaround crew needs — and deliver to Sulphur, Westlake, and Moss Bluff 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 Lake Charles plants operating under ASME and API requirements can’t do without. And with our team answering the phone 24 hours a day, a Lake Charles turnaround that runs long always has someone to call.
If your Lake Charles 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.
