Louisiana’s petrochemical corridor runs some of the most demanding fabrication and process work in the country. The vessels being built and maintained along the Baton Rouge to Lake Charles stretch are large, code-critical, and built to operate under extreme conditions. That’s exactly the kind of work Gulf Coast Combustion was built for.
If you’re building high-pressure, thick-walled pressure vessels and need a mobile heat treating partner who shows up, executes clean, and hands you full documentation before they leave — call our owner James Benefield directly at 832-797-3428. He answers calls and texts personally, including short notice and emergency jobs.

No receptionist. No call queue. No waiting on a callback from someone who wasn’t on the last job.
The Baton Rouge to Lake Charles stretch is one of the most concentrated refining and chemical processing regions in the world. Facilities along this corridor — refineries, LNG terminals, chemical plants, and the fabrication shops that supply them — are building and repairing vessels that operate under sustained high pressure and temperature. The margin for error in heat treating those vessels is zero.
GCC brings the equipment directly to your facility. Our mobile direct gas fire combustion systems handle the largest vessels fabricated in this region, with gas trains running up to 8 million BTU.
Every heat treatment performs in full accordance with ASME Section VIII Division 1 / UCS-56 or any customer-provided specification. For a full breakdown of what those requirements mean in practice, see our post on PWHT requirements under ASME Section VIII.
No Transport
No oversized load permits. No rigging. No transit risk. Your vessel never leaves your yard.
On-Site QC Witness
Your QC team monitors chart recorder data in real time throughout the entire cycle.
ASME Compliant
Every job executed to ASME Section VIII or your customer-specified WPS and code requirements.
Full Docs Before We Leave
Heat treat record, strip chart trace, calibration certificate, execution plan — complete before GCC trucks leave your yard.
For thick-walled, high-pressure pressure vessels, direct gas fire combustion delivers uniform, controllable heat across large surface areas. Our Type K thermocouples with capacitor discharge attachment and NIST-calibrated Chino recorders monitor and document every phase of the cycle, from initial heat-up through soak and controlled cool-down. For more on how the method works, see what direct gas fire heat treating is and why it matters.
We follow ASME Section VIII parameters on ramp rates, soak temperatures, and hold times on every job. Our standard soak temperature is 1,150°F ±50°F. Heat-up and cool-down rates are calculated by wall thickness. Nothing is guessed, and nothing is left undocumented.
Direct gas fire combustion, on-site, right where the vessel sits. No furnace. No transport. James Benefield is involved in every job.
Time lapse: 621,000 lb vessel, Central Texas. Direct gas fire combustion, on-site.

Getting a quote from GCC is straightforward. Here’s how it works.
Send us your specs
Drawings are ideal, but vessel weight, length, width, and wall thickness get us started. Email james@gulfcoastcombustion.com or call 713-425-3773.
We price it out
James reviews your specs personally and turns around a quote fast. No waiting on a sales team.
We schedule and mobilize
GCC is available on short notice. If your timeline is tight, tell us up front — we work around fabrication schedules regularly and can mobilize faster than you’d expect.
Full documentation before we leave
Every job includes a complete documentation package: heat treat record, strip chart recorder trace, calibration certificate, and written execution plan. Your QC package is complete before GCC trucks leave your yard.

Mobilization timeline depends on current project load, but we move fast. The drive from Spring, TX to Baton Rouge is under 5 hours — we’re not flying in from across the country. Call 713-425-3773 or text James at 832-797-3428 to discuss your schedule.
Our mobile equipment handles vessels of virtually any size. We have treated vessels over 100′ long and 600,000 lbs on-site. For most large vessels, furnace transport is possible — it’s just not cost effective. Oversized load permits, rigging, transit risk, and furnace scheduling all add up. On-site heat treating eliminates that entire cost category.
Yes, and we encourage it. Your team can monitor chart recorder data in real time throughout the entire cycle.
All the time. We walk first-time clients through the full process before the job starts — thermocouple placement, documentation requirements, what to expect during heat-up and hold. No surprises.
Yes. The chemical manufacturing corridor along the Mississippi River between Baton Rouge and New Orleans is well within our regular service area — and exactly the kind of high-demand industrial market we work in regularly.
Based in Spring, TX. Available Nationwide.
