The Dallas/Fort Worth metroplex is one of the largest industrial manufacturing markets in Texas — a diverse base of custom fabricators, ASME pressure vessel shops, and industrial equipment manufacturers serving oil & gas, chemical processing, power generation, and midstream clients across the region. Gulf Coast Combustion has performed on-site pressure vessel PWHT and refractory dry outs for clients in North Texas and we’re equipped to support this market with the same direct gas fire combustion execution we’ve delivered across the Gulf Coast since 2014.
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.

DFW’s industrial base looks different from Houston’s — less refinery concentration, more fabrication shops building custom pressure vessels, heat exchangers, and process equipment for clients across multiple industries. The Grand Prairie, Irving, and Kennedale fabrication corridor supplies midstream operators, chemical processors, and industrial manufacturers across Texas and beyond. These vessels are built to ASME Section VIII Division 1 standards and require code-compliant PWHT before they go into service.
GCC brings the equipment directly to your facility. Our mobile direct gas fire combustion systems handle vessels of any size, with gas trains running up to 8 million BTU.
West of Dallas, the Mineral Wells corridor supports active oil & gas equipment fabrication. GCC has worked in this market and has mobilized to North and Central Texas repeatedly. Dallas is roughly 4 hours from our Spring, TX shop — well within our regular range. For a breakdown of what PWHT requirements look like 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.
Choosing a Contractor
Anyone Can Own the Equipment. Not Everyone Can Cook a Vessel.
The gap between a real specialist and someone with the same gas trains doesn’t show on a spec sheet. It shows on the vessel. Here’s how to tell the difference before you hand one your fabrication.
How to Vet a PWHT Contractor →Why Direct Gas Fire Combustion
For thick-walled, high-pressure pressure vessels — the kind being built for oil & gas, chemical processing, and industrial applications across North Texas — 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. For more on the method, 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.

What Happens After You Call
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.
Frequently Asked Questions
How quickly can GCC mobilize to a Dallas/Fort Worth job?+
Dallas is roughly 4 hours from our Spring, TX shop — a straightforward run we’ve made before. For jobs with lead time, we plan mobilization around your fabrication schedule. For tight timelines, call James directly at 832-797-3428 and he’ll give you a straight answer on availability.
What vessel sizes do you handle?+
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 fast. On-site eliminates that entire cost category.
Can our QC team witness the heat treatment?+
Yes, and we encourage it. Your team can monitor chart recorder data in real time throughout the entire cycle. Everything is visible and documented as it happens — no black box, no waiting on paperwork after the fact.
Do you work with fabricators who haven’t used mobile PWHT before?+
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 on job day.
Do you serve the Mineral Wells and West Texas fabrication corridor?+
Yes. The Mineral Wells area and the broader West Texas corridor are well within our range from Dallas. If your shop is outside the DFW metro, call us with your location and vessel specs — we’ll give you a straight answer on mobilization.
Is on-site PWHT cost competitive with shipping a vessel to a furnace from DFW?+
For large vessels, almost always yes. The freight cost on an oversized load from DFW to a furnace shop, plus permits, rigging, and the return trip, adds up fast. Call us with your vessel specs and we’ll give you a number to compare against your current furnace quote.

The Hidden Cost of Shipping Your Vessel to a Furnace
DFW fabricators sending vessels to a heat treating furnace are taking on costs and risks that don’t show up in the heat treating quote:
- ✕ Heavy haul transport — permits, escorts, scheduling delays
- ✕ Rigging at pickup and delivery — twice
- ✕ Furnace queue — your vessel waits behind someone else’s job
- ✕ Transit damage risk on a vessel you just built
- ✕ You’re not there when it’s treated — no visibility on execution
On-site PWHT eliminates every one of those. See the full on-site vs. furnace comparison.
