QMS offers world-class conventional S-Lay pipeline installation services. This includes pipeline welding solutions ranging from industry standard downhill cellulosic (stick) welding or shielded metal arc welding (SMAW) to the more advanced mechanized gas metal arc welding (GMAW) with both, single and dual torch operations. Pipelay welding solutions can range from typical carbon-manganese based material systems (carbon steel pipe) and non-ferrous materials including exotic metals 13% Cr, duplex stainless steels and Inconel 625. QMS has the experience required for solving the most critical subsea pipeline weld design requirements and onerous engineering critical assessments for all manner of conditions including severe sour service conditions.
Post welding, QMS provides the full pipeline production services including the Radiographic Testing (RT) and Automated Ultrasonic Testing (AUT) methods of girth weld inspection. Field joint coating solutions range from standard Fusion Bonded Epoxy (FBE) with and without polyurethane foam in-fill to the more complex Injection Molded Polypropylene (IMPP) systems.
