Pipe welding
Qualified pipe welding for systems that can't leak.
Pipe is where welding gets honest: the joint either holds pressure or it doesn't. Our pipefitters and welders run TIG pipe to qualified procedures on shipboard hydraulic, seawater, and auxiliary systems — and bring the same qualified-procedure discipline to industrial piping ashore.

- Marine piping — hydraulic, seawater, auxiliary systems

Frequently asked questions
Are your pipe welders qualified?
Yes — our welders hold qualifications for TIG (GTAW) pipe among other procedures, and every joint is executed and documented to spec.
Do you handle marine piping systems?
Daily. Hydraulic, seawater, and auxiliary shipboard systems are core work — repair, renewal, and new installs.
