Sandvik will offers weld-free coiled tubing in lengths exceeding 1000m. The first 1010m coiled tube reel is to be symbolically delivered on 10 October 2016 for a demanding offshore oil and gas customer.
To meet a growing need for coiled tubing in very long lengths, Sandvik’s tubing unit in Werther, Germany has developed a method that enables the production of stainless tubing in lengths exceeding 1000m from a single 125kg hollow – with zero welds. The new production technique is a combination of pilgering, drawing and proprietary processes.
“No matter how skilled you are at welding, there is always a risk of cracking or corrosion,” said Christofer Hedvall, managing director of the tubing unit. “With our new production method, we take risk completely out of the equation.”
Production is expected to be up and running at its facility in Werther by June with the first 1010m coiled reel order supplied on 10 October 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.
