What we offer

Versatility and Experience

From 72″ large-bore, extra-heavy wall, carbon-steel pipe utilizing sub-arc welding (SAW), to 1/4″ orbitally-welded stainless steel tubing, our process piping capabilities cover a broad spectrum of material and weld specification in varied code-requirements.

We maintain 300+ pipefitters on our payroll with craft supervisors averaging 25 years of industry experience across a diverse customer base. This field experience is enhanced by a deep bench of in-house BIM/3D CAD designers and 200,000 sq ft of fabrication and module assembly facilities with over 300 qualified weld procedures.
