Process Columns
Large-diameter alloy towers, trayed and dressed out.
ASME code pressure vessels, reactors and towering alloy process columns — engineered, fabricated and shipped on the critical path for America's refineries and petrochemical plants.
One critical-path process column — fabricated in 78 days, then dressed out with TSA, insulation, intumescent fireproofing and trays in under 40 — left our floor ahead of schedule. That's the answer to the only question that matters on a plant deadline.
Every handoff is a place a schedule can slip. So we eliminated them. Your vessel is engineered, fabricated, tested, blasted, painted, insulated and fireproofed inside our own walls — one accountable team, start to ship.
Code. Precision. Performance. Self-qualify our shop against your spec — from towering process columns to high-pressure reactors, all made in the USA.
Large-diameter alloy towers, trayed and dressed out.
ASME Sec VIII Div I & II up to 15,000 PSI.
Heavy-wall reactors in exotic and clad alloys.
Field- and shop-built storage, accumulators and drums.
Shop-fabricated spools, skids and weld overlay.
Pipe racks, supports and structural steel to code.
The question every plant engineer asks: is this shop qualified for high-spec, code-compliant vessels? Our procedure library and certified inspectors answer it before you ever send a drawing.
Refiners trust their budget and their timeline to people who will still be here for the next turnaround. GCAW has stayed under continuous, single ownership since 1981 — so the accountability that builds your vessel is the same accountability that answers the phone.
One owner, one standard, no shifting hands on your project.
40+ years of critical-path projects for refiners and chemical plants.
Engineered and fabricated in Humble, Texas — start to ship.
Send us your spec. We'll come back with an expedited, code-compliant fabrication plan — engineered, built, tested and dressed out under one roof.
