Trusted since 1981

Our reputation
is stainless.

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.

The critical-path proof

When the turnaround clock is running, we don't blink.

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.

End-to-end · under one roof

One facility.
Every step.

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.
