Product Families

Division 1 Pressure Vessels (U Stamp)

Vessels designed by rule under ASME Section VIII Division 1 and carrying the U Code symbol stamp, covering the broad majority of process vessels at moderate pressures.

Division 2 High-Pressure Vessels (U2 Stamp)

Vessels built to the more rigorous design-by-analysis rules of Section VIII Division 2 and bearing the U2 stamp, used where higher pressures, thicker walls, or stricter material and fatigue requirements apply.

Separators and Knockout Drums

Two- and three-phase separators, scrubbers, and slug catchers that divide produced oil, gas, and water streams using gravity and internal devices such as mist extractors and baffles.

Shell-and-Tube Heat Exchangers

Code-stamped exchanger shells and channels that transfer heat between two fluids through a bundle of tubes, used for cooling, heating, and condensing in process service.

Filter, Coalescer, and Surge Vessels

Pressure housings that hold filter or coalescer elements, or provide accumulation and surge volume, to remove particulates and liquids or buffer flow in gas and liquid systems.

Stainless Steel Vessels

Vessels fabricated from austenitic, duplex, or other stainless grades for corrosive, sour, or high-purity service where carbon steel would not provide adequate corrosion resistance.

Carbon Steel Vessels

Vessels fabricated from carbon and low-alloy steel plate for general process and storage service, the most common material class for hydrocarbon duty.

Code Repair and Alteration Services (R Stamp)

Repair, re-rating, and alteration of in-service pressure vessels performed under the National Board Inspection Code R Certificate of Authorization to restore or modify a registered vessel.
