PWHT Requirements Under ASME Section VIII
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 can get complicated. Here’s a practical breakdown. Gulf Coast Combustion has been executing ASME-compliant pressure vessel […]
Post Weld Heat Treating: Can It Be Done On-Site?
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 Combustion has been performing on-site PWHT using direct gas fire combustion since 2014, mobilizing directly to fabrication shops and plant sites across the Gulf Coast and the U.S. Here’s how […]
Heat Treatment Equipment — Gas Train & Burner Systems
When Gulf Coast Combustion shows up on a job site, the heat treatment equipment setup is what the industry calls gas train equipment. It’s the core of direct gas fire combustion heat treating — the method GCC has specialized in since 2014. Here’s a breakdown of what each component is, what it does, and why […]
Time Lapse of on-site PWHT pressure vessel
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 video walks you through the complete on-site pressure vessel heat treating process: initial setup, cook, temperature recording, and strip out on a massive custom-engineered 70′ x 16′ high-pressure vessel weighing […]
