Every order of Alloy 400 ships with a complete set of original Mill Test Reports, with traceability not only to the manufacturer but to the origin of the material.
Nominally 63% minimum nickel with 28–34% copper and small additions of iron and manganese, giving a single-phase solid-solution alloy.
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 longstanding refinery, material selection is not a place to cut corners. Alloy 400 (UNS N04400) delivers the performance that El Dorado’s refining and chemical operators depend on, and P.A. Inc. keeps it on the shelf — ready for fast delivery across Arkansas.
The reason El Dorado engineers keep coming back to Alloy 400 comes down to its metallurgy — excellent resistance to seawater and high-velocity brackish water and resists hydrofluoric and sulfuric acids across a range of concentrations. In demanding refining and chemical service, those properties are the difference between a component that lasts a campaign and one that fails early.
Our El Dorado customers put Alloy 400 to work across the demanding end of process service: marine and offshore seawater piping systems, hydrofluoric acid alkylation units, valve, pump and shaft components in chemical service, and feedwater and steam-generator heaters. 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 El Dorado turnaround crew needs — and deliver to Smackover, Norphlet, and Junction City and the surrounding region without the freight time of pulling material from out of state.
Every length of Alloy 400 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 El Dorado plants operating under ASME and API requirements can’t do without. And with our team answering the phone 24 hours a day, a El Dorado turnaround that runs long always has someone to call.
If your El Dorado operation needs Alloy 400 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.
