Piping/tubing

NLI has extensive experience for pipe welding for both carbon steel & stainless steel materials.

Our track record especially from subsea pipe fabrication keeps us at the highest level of quality for pipe welding in the market.

IWI- S / NS 477 weld inspectors monitor before, the welding process during and after welding on regular basis.

Fabrication certified according to EN-1090 and ISO 3834-2 Welding certification, and we hold a large library of prequalified welding procedures.
