A photo of a 55-foot pressure vessel at 1,150°F made its way onto a major engineering community online. Within 24 hours: 503 upvotes, 70+ comments,

We don’t transport the vessel to a furnace. We turn it into one. A complete breakdown of on-site vs. shop furnace PWHT — cost, transport risk, size limits, schedule control, and documentation. Everything fabricators need before they choose.

Refractory lining is expensive. The installation labor alone makes it one of the higher line items on any heater or vessel turnaround. The dry out

You’ve got a vessel ready for furnace PWHT. You’re calling furnace shops, getting freight quotes, checking schedules. That’s the process most fabricators run — because

If you’ve ever wondered how long on-site pressure vessel PWHT takes, here’s the straight answer: for most jobs, Gulf Coast Combustion is on your floor

The first time one of our longest-running clients saw on-site pressure vessel PWHT, he didn’t describe it in technical terms. He said it looked like

Not all mobile heat treating companies are created equal. For pressure vessel fabricators, choosing the wrong vendor can mean schedule delays, execution problems, or a

Pipe spools, flange faces, nozzle welds, and seam weld repairs all require post weld heat treatment on a specific area — not a full vessel

Pressure Vessel PWHT by Vessel Type: What Fabricators in Oil & Gas and Petrochemical Need to Know If you fabricate pressure vessels for oil &

Refractory lining is a significant investment — in materials and in the labor to install it. The dry out process is the final step before

There’s a particular kind of fabrication shop that stands out in the pressure vessel heat treating world. Their work is precise. Their timelines are tight.

Most fabricators picture a box furnace when they think about heat treating. Gulf Coast Combustion uses something different — high-velocity direct gas fire combustion. It’s

If you’re a pressure vessel fabricator who relies on an outside furnace for PWHT, you’re probably already feeling the pressure of rising transportation costs —

If you fabricate pressure vessels, post weld heat treatment (PWHT) isn’t optional — it’s a code requirement driven by ASME Section VIII, Division 1. But

Yes. Post weld heat treatment can absolutely be done on-site — and for large, heavy pressure vessels, it’s almost always the right call. Gulf Coast

When Gulf Coast Combustion shows up on a job site, the equipment setup is what the industry calls gas train equipment. It’s the core of

Watch Gulf Coast Combustion perform on-site pressure vessel heat treating from start to finish — captured in a 90-second time-lapse at a customer location. This

Thermal insulation is a critical component of every on-site pressure vessel heat treating job. In industrial heat treating, the term refers specifically to glass fiber
