Whatever your requirements, we work with you to build the right vessel, on time and at a competitive price.

Penfabco is a pressure vessel specific shop.

We handle drafting, fabrication, welding and inspection under one roof, with an ABSA inspector and NDT services on site daily so we're never slowed down waiting for inspectors or x-ray. Our location near major roadways gives third-party inspectors, trucking and customers easy access, and we sit five blocks from heat treatment services.
