Spiral Seam Welded Pipe GBT9711 2011PSL2
We are pleased to introduce our newest product, spiral seam welded pipe. This innovative multi-functional product is made by rolling low-carbon carbon structural steel or low-alloy structural steel strips into tube blanks at a certain spiral angle, and then welding the tube seams. This unique manufacturing process allows us to produce large diameter steel pipes from relatively narrow strips.
At Cangzhou Spiral Steel Pipes Group Co., Ltd., we take great pride in our state-of-the-art facilities and cutting-edge technology. Covering an area of 350,000 square meters and with total assets of 680 million yuan, it has become a leader in the industry. With a dedicated team of 680 employees, through unremitting efforts, the company has an annual output of 400,000 tons of spiral steel pipes and an output value of 1.8 billion yuan.
