5 Questions to Ask Before You Hire a Mobile Heat Treating Company
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 heat treat cycle that doesn’t meet code. Here are five questions worth asking before you award a job. 1. How Much Experience Does the Mobile Heat Treating Company Have With […]
Localized PWHT: Pipe Spools, Nozzle Welds, and Vessel Repairs
Pipe spools, flange faces, nozzle welds, and seam weld repairs all have one thing in common — they require post weld heat treatment on a specific weld area, not a full vessel treatment. Localized PWHT is the right tool for this work, and it’s one of the more common jobs Gulf Coast Combustion performs alongside […]
Pressure Vessel PWHT by Vessel Type: What Fabricators in Oil & Gas and Petrochemical Need to Know
Pressure Vessel PWHT by Vessel Type: What Fabricators in Oil & Gas and Petrochemical Need to Know If you fabricate pressure vessels for oil & gas, chemical processing, or petrochemical applications, you already know that post weld heat treatment is code-required on most of what you build. What’s less often discussed is how the vessel […]
Refractory Dry Out: Why Getting It Right the First Time Matters
Refractory lining is a significant investment — in materials and in the labor to install it. The dry out process is the final step before the refractory goes into service, and it’s one that gets underestimated more than it should. A poorly executed dry out is one of the most common causes of premature refractory […]

Why the Best Pressure Vessel Fabricators Don’t Shop for a New Heat Treating Vendor Every Year
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. Their clients — refineries, chemical processors, upstream oil and gas operators — don’t tolerate delays or rework. These shops have one thing in common: they stopped treating pressure vessel heat […]
What Is Direct Gas Fire Heat Treating — and Why Does It Matter for High-Pressure Vessels?
Understanding the Method Behind Gulf Coast Combustion’s On-Site PWHT Process When people hear “heat treating,” they often picture a box furnace or electric resistance elements. Gulf Coast Combustion specializes in something different: direct gas fire heat treating for high-pressure vessels using high-velocity combustion. It’s worth understanding what that means and why it produces excellent results […]
Why Rising Oil Prices Favor On-Site PWHT
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 — and it’s likely to get worse before it gets better, which is why on-site PWHT cost savings have never been more significant for fabricators. Brent crude oil has surged nearly […]
PWHT Requirements Under ASME Section VIII
What Pressure Vessel Fabricators Need to Know: Understanding the Code Requirements That Drive Your PWHT Decisions 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 understanding exactly when it’s required, and what the parameters look like, is where things […]
Post Weld Heat Treating: Can It Be Done On-Site?
On-site Post weld heat treatment raises an immediate practical question: do you transport the work to a furnace, or bring the heat treating to you? For most industrial applications — pressure vessels, refractory dry outs, and combustion services across oil & gas, chemical processing, and petrochemical facilities — the answer is almost always the same: […]
