OIL & GAS STAINLESS STEEL FABRICATION ON THE GULF COAST
When the stream is sour or chloride-heavy, carbon steel will not last and the line has to be stainless. JMC Fabrication fabricates 304 and 316 stainless piping for oil and gas EPC contractors and industrial facilities from our AWS certified shop in Pascagoula, MS, with the weld controls and documentation corrosion-critical service requires.
Sour service, high chloride content, and aggressive process media attack carbon steel quickly. Stainless steel resists that corrosion, and the grade matters: 316 carries molybdenum that holds up better against chlorides than 304, which is why it is common on the most aggressive streams. JMC confirms the grade against the service conditions at the quote stage so the weld procedure and documentation follow it.
JMC fabricates stainless for the corrosion-critical scope EPC packages require:
- 304 and 316 stainless pipe spools and process piping
- Flanges, nozzles, and fittings fabricated to specification
- Custom stainless weldments and equipment piping
- Fabrication from customer isometrics or JMC-reviewed drawings
- Weld mapping and full traceability per package
Stainless is less forgiving than carbon steel. Heat input, filler selection, and cleanliness all affect the corrosion resistance of the finished weld, and poor control can undo the reason stainless was specified. JMC's AWS certified welders work to qualified procedures for stainless, with the controls that protect corrosion performance through fabrication.
- Material test reports and mill certifications per heat
- Weld maps and weld logs per package
- NDE documentation per project specification
- Project closeout documentation packages
- Traceability tying every line back to its grade
JMC is based in Pascagoula, MS on the Gulf Coast industrial corridor, with access to the region's offshore, petrochemical, and LNG supply chains. Southeast delivery is efficient, and nationwide shipping is available for larger EPC accounts.

What stainless grades does JMC use for oil and gas piping?
JMC fabricates 304 and 316 stainless steel for oil and gas process piping, with 316 common on sour service and high-chloride streams. Contact us to confirm additional grades and schedules required by your specification.
Why is 316 stainless used for sour service and chloride-heavy streams?
316 stainless contains molybdenum, which improves resistance to chloride-driven pitting and corrosion compared to 304. That makes it the common choice for the most aggressive oil and gas streams.
Is JMC certified to weld stainless for oil and gas work?
Yes. JMC's AWS certified welders work to qualified procedures for stainless steel, with the heat and cleanliness controls that protect corrosion performance in process service.
What stainless components does JMC fabricate for oil and gas?
JMC fabricates stainless pipe spools and process piping, flanges, nozzles, fittings, and custom weldments for corrosion-critical oil and gas applications.
What documentation comes with stainless oil and gas fabrication?
Each package includes material test reports and mill certifications per heat, weld maps and weld logs, NDE documentation per specification, and a project closeout package tying every line back to its material grade.
