Pressure Vessel Components

ASME & CE Certified Heavy Fabrication

Manufacturing components for pressure vessels, heat exchangers, and chemical reactors leaves absolutely no room for error. Because these parts operate under extreme pressure and temperature variations, they demand flawless metallurgy, certified heavy welding, and zero-defect machining.

With 180 acres of manufacturing space, 250-ton lifting capacities, and strict adherence to global boiler and pressure vessel codes, Openex is the trusted contract manufacturer for the world's leading energy and petrochemical engineering firms.
