Our high-frequency welded pipe production line is a state-of-the-art solution for the continuous production of straight seam welded pipes. Utilizing advanced high-frequency induction welding, our line is capable of producing not only round pipes but also corresponding square, rectangular, and other special-shaped pipes with exceptional precision. A key innovation in our design is the "shared sizing roll" technology: the same set of sizing rolls can be used for producing various pipe shapes and sizes, demonstrating our advanced engineering and optimizing production efficiency. This eliminates the need for frequent roll changes, saving significant time and reducing operational costs. The versatile high-frequency pipe welding machine is ideal for the production of a wide range of pipes, including iron pipes, construction pipes, structural pipes, water pipes, oil pipes, and API pipes. Our technology provides reliable, efficient, and high-quality pipe production solutions.
