The high-frequency straight seam welded pipe mill is used to level the fixed strip after slitting line, and send it to forming machine, bend to open pipe by roller, melt the strip edges through the high-frequency current, squeeze and weld the pipe to be closed by the squeeze roll. The high-frequency pipe mill is also called ERW pipe mill. Our fully-automatic FFX HFW production line and multifunction 250mm-500mm directly-formed square pipe line are among the highest in the industry.

For steel pipe manufacturers, delivering the best value for money is the key to winning over pipe customers. To do so, they need advanced manufacturing processes backed up by top-notch equipment. Wanxin as a specialist ERW pipe mill manufacturer works with many well-known steel pipe makers in the world, helping them design and build welded pipe production lines for high quality pipes in rectangular and round cross sections. In doing so, steel pipe suppliers can meet their customers’ needs in terms of budget and cost-performance ratio.
Presently in China, Wanxin ERW pipe mill is in operation for many steel pipe companies, like Hengshui Jinghua, Chongqing Shengmin, and Rizhao Jinghua, just to name a few. Many international customers have shown their interest in our welded pipe machinery, and are actively negotiating with us for our high-frequency pipe welder, stainless steel pipe welding machine, and high-precision pipe welder.
