NORSOK super duplex approval for Fine Tubes

Critical application precision tubing manufacturer Fine Tubes has received NORSOK approval to supply the oil and gas industry with UNS S32750 seamless straight length tubing in the wall thickness range of 1mm to 3.98mm.

The NORSOK M-650 standard verifies through a set of established requirements that a manufacturer has sufficient competence with the relevant material grades, including Super Duplex stainless steel, as well as the necessary manufacturing facilities and equipment. Qualification is valid for five years.

Fine Tubes secured this additional approval by aligning its manufacturing process with NORSOK M-650 requirements and by demonstrating its compliance through audits undertaken by One Subsea. The process, which was made possible through a frame agreement with One Subsea and TW Metals, brings Fine Tubes into the global supply chain for all One Subsea sites.

Chris Burridge, Customer Quality Engineer for Fine Tubes, commented: “This is great news for us, adding another feather to our NORSOK hat and opening up further opportunities for us. Working in partnership with One Subsea gave us the dialogue we needed to qualify.”

The Super Duplex NORSOK approval applies to Fine Tubes’ Plymouth site and covers a specific routing with specific equipment and complements the company’s existing 6Mo NORSOK approval.

Fine Tubes works closely with its sister company, US-based Superior Tube, across all of its key markets, including oil and gas.
