In order to meet the increasing demand for coiled tubing in very long lengths, Sandvikâs high-precision tubing unit in Werther, Germany has recently developed a breakthrough method enabling the production of stainless tubing in lengths exceeding 1,000 meters from a single 125 kg hollow with zero welds.
âNo matter how skilled you are at welding, there is always a risk of cracking or corrosion,â? says Christofer Hedvall, Managing Director of the high-precision tubing unit. âWith our new production method, we take risk completely out of the equation.â?
Production is expected to be up and running at its facility in Werther by June with the first 1,010 meter coiled reel order supplied on October 10, 2016. While the initial order is from the oil and gas sector, Sandvik anticipates that other industries could find this extended-length technology to be useful as well.
âThis is the result of an ongoing innovation journey that started some years back,â? says Mr. Hedvall, noting that the company is now introducing nickel alloy tube Alloy 625 (Sanicro⢠60) and Alloy C276 (Sanicro⢠56), has received ISO 50001 certification (a major part of the Green Factory approach), NORSOK approval and DIN EN 9100 qualification.
