If you’re looking for pressure vessel heat treating in Houston, you have two options: ship the vessel to a furnace, or have the heat treating come to you. Gulf Coast Combustion brings the equipment to your facility — gas trains up to 8 million BTU, vessels of any size, full ASME documentation on every job. Based in Spring, TX since 2014, we’ve been doing this in the Houston market longer than most.
“If you can build it, we can heat treat it on-site.”
— James Benefield, Owner, Gulf Coast Combustion
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.

The furnace quote looks like one number. It never stays that way. Every large vessel job adds costs that don’t show up until after you’ve committed:
Heavy haul transport
Lowboys, multi-axle trailers, SPMTs — thousands of dollars each way before fuel surcharges.
Oversized load permits
Every state the vessel crosses requires permits, route surveys, and in some cases escort vehicles.
Crane rigging at both ends
Lift out of your yard, set at the furnace, then the whole process runs in reverse on the way back.
Furnace scheduling
You’re working around their availability, not yours. That adds days or weeks that don’t show in the quote.
Transit damage risk
Even minor damage on a finished vessel means rework, a delayed delivery, and a difficult conversation with your client.
For Houston fabricators building vessels that are already large, already set in position, or already pushing your schedule — shipping to a furnace isn’t just expensive. It’s a risk you don’t need to take.
Full Comparison
Cost, schedule, risk, documentation — every factor compared side by side for large pressure vessels.
Read the Full Comparison →The alternative to on-site PWHT is trucking your vessel to an outside furnace. For large pressure vessels — anything over 30,000 lbs, anything with an oversized footprint, anything already set in position — that creates real problems. Oversized load permits, rigging, transit risk, furnace scheduling: every one of those variables adds cost and time to your project.
GCC brings the equipment to your vessel. Your vessel stays on your floor. Your QC team witnesses the process in real time. Your documentation is in hand before we leave. Every heat treatment is performed in full compliance with ASME Section VIII Division 1 / UCS-56 or any customer-provided WPS and specification.
No Transport
No oversized load permits. No rigging. No transit risk. Your vessel never leaves your yard.
On-Site QC Witness
Your QC team can monitor 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.
Owner James Benefield walks through a live job at a Houston-area fabrication shop — 133,000 lbs, 3-inch wall thickness, brought to 1,150°F on-site using direct gas fire combustion. No furnace. No transport.
A 600,000 lb pressure vessel. Wrapped, fired, and fully documented on-site. 72 hours of work in 90 seconds.
This is a vessel over 70 feet long and 600,000 lbs, heat treated on-site using direct gas fire combustion. No furnace. No transport. Full documentation package delivered before GCC left the yard.

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.

Greater Houston is one of the most active pressure vessel heat treating markets in the country. The northwest corridor — Brookshire, Katy, Cypress, Tomball, Conroe — has grown significantly as fabricators have moved west to access land, labor, and lower costs. GCC has grown with it.
We also serve the traditional southeast Houston and Pasadena corridor, Freeport and the Brazosport petrochemical complex, and the broader Gulf Coast region. For major operators headquartered in The Woodlands, we’re your backyard vendor.
Houston proper — from the Ship Channel to downtown industrial facilities — is home base. We’ve been working in this city since 2014. No part of greater Houston or the Gulf Coast is out of range.

More From Gulf Coast Combustion
Refractory dry outs, paint and coating cures, and more — Gulf Coast Combustion is a combustion specialist serving the Gulf Coast with high-velocity gas combustion systems since 2014.
For local Houston jobs, if we’re available, we can mobilize immediately or next day if schedule allows. Call 713-425-3773 or text James at 832-797-3428 to check availability.
Our mobile equipment handles vessels of virtually any size. We have treated vessels over 120′ 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 petrochemical complex along the Brazosport corridor is well within our regular service area and a market we know well.
It depends on wall thickness, vessel size, and job complexity. Heat-up rate, soak time, and cool-down all follow ASME code requirements — there’s no shortcut on any of it. Most vessels are completed in 2–3 days. See the full timeline breakdown.
Serving Houston & the Gulf Coast. Available Nationwide.
