From our plant, or built on your site
Our Valencia headquarters has well over 120,000 sq ft of factory space designed for ASME pressure vessel fabrication, and ships vessels up to 16 ft in diameter and more than 100 ft long.
For vessels too large to ship, our field crews fabricate on site. We have built some of the world's largest ASME-certified pressure vessels for the composite bonding industry, and fabricate certified vessels around the globe.
