On-Site Heat Treating — Wichita Falls & Southern Oklahoma

Wichita Falls sits right at the Texas-Oklahoma border — and the industrial activity on both sides of that line is exactly what Gulf Coast Combustion was built to serve. Oil and gas production, refining, chemical processing, and heavy industrial fabrication in northern Texas and southern Oklahoma all generate real, consistent demand for pressure vessel heat treating done to code. When fabricators in this region need mobile PWHT they can count on, GCC comes to them.

We provide on-site PWHT via direct gas fire combustion throughout the Wichita Falls region and into southern Oklahoma. No furnace queue. No transport risk. Call our owner James Benefield directly at 832-797-3428. He answers calls and texts personally, including short-notice and emergency jobs.

Wichita Falls & Southern Oklahoma — North Texas Refining & Oilfield Corridor

Wichita Falls has its own refining history — Frontier Refinery has operated here for decades — and the surrounding region supports active oil and gas production, petrochemical operations, and pipeline infrastructure. Fabricators here are building custom-engineered pressure vessels for clients that need code-compliant PWHT on schedule. The nearest large furnace shop is a long haul from this corridor. GCC eliminates that problem by coming to you.

Across the Red River, southern Oklahoma adds to the picture. Lawton’s industrial manufacturing base, the Ardmore oil patch, Duncan’s oilfield service corridor, and the broader Oklahoma City region all represent active fabrication markets that GCC reaches efficiently from this zone. Spring, TX to Wichita Falls is roughly four hours — a straightforward mobilization for scheduled and short-notice jobs alike.

The Hidden Cost of Shipping Your Vessel to a Furnace

North Texas and southern Oklahoma 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.

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.

Why Direct Gas Fire Combustion

For thick-walled, high-pressure pressure vessels — the kind being fabricated for oil and gas production, refining, and industrial operations across northern Texas and southern Oklahoma — 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.

This Is What On-Site PWHT Actually Looks Like

Direct gas fire combustion, on-site, right where the vessel sits. No furnace. No transport. James Benefield is involved in every job.

What Happens After You Call

Getting a quote from GCC is straightforward. Here’s how it works.

1

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.

2

We price it out

James reviews your specs personally and turns around a quote fast. No waiting on a sales team.

3

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.

4

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 Wichita Falls or southern Oklahoma?+

Wichita Falls is roughly four hours from our Spring, TX shop. Lawton and Ardmore, OK are within range from the same mobilization. For scheduled jobs, we plan around your fabrication timeline. For tight deadlines, 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 Burkburnett, Vernon, Lawton, and the surrounding region?+

Yes — GCC mobilizes throughout Wichita Falls, Burkburnett, Vernon, and the Texas-Oklahoma border corridor including Lawton, Ardmore, and Duncan in southern Oklahoma. Call us with your location and vessel specs and we’ll give you a straight answer on mobilization.

Is on-site PWHT cost competitive with shipping a vessel to a furnace from this region?+

For large vessels, almost always yes. The nearest large furnace shop from northern Texas or southern Oklahoma is a long haul — freight, permits, rigging, and the return trip add up fast. Call us with your vessel specs and we’ll give you a number to compare against your current furnace quote.
