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 600,000 lbs.
The Process
First, the heat treatment uses ceramic fiberglass insulation along with high-velocity direct gas fire combustion equipment to complete PWHT in full accordance with ASME Section VIII Division 1 / UCS-56, or any other customer-provided specifications. On-site PWHT of thick-walled, heavy-wall pressure vessels built for oil & gas and chemical processing applications typically takes GCC an average of 36-72 hours, depending on vessel size and wall thickness.
Direct gas fire combustion is one of the most efficient methods available for on-site pressure vessel heat treating. It delivers uniform, controlled heat across large custom-engineered vessels that can’t be moved to a shop furnace. It’s the method GCC has specialized in since 2013, performing more on-site pressure vessel heat treatments per year than any other mobile heat treating company in the U.S.
What You’ll See in the Video
- Initial insulation wrap of the full vessel
- Combustion equipment setup and gas train connection
- The cook cycle and live temperature recording
- Full strip out and completion
In total, the entire PWHT process — which in real time runs 36-72 hours — is condensed into about 90 seconds of time-lapse footage.
About Gulf Coast Combustion
