The terms tube mill, steel pipe, pipe mill, and ERW pipe are intrinsically linked in the context of modern metal forming technology. Shijiazhuang Faith Machinery Co., Ltd. provides integrated machinery systems that transform raw steel coil into finished welded steel pipe or tube, a process central to many industrial supply chains.
A tube mill, or pipe mill, is the complete production line. It is an interconnected sequence of machines that performs several functions. It starts with material handling, which includes a decoiler to hold the steel coil and a feeding mechanism. A precision leveler then removes any coil set or curls, ensuring the strip is flat before it enters the forming section. The forming process is progressive, using a tandem set of contoured rolls to bend the flat strip into a cylindrical shape with its edges prepared for welding.
For the production of ERW (Electric Resistance Welded) pipe, the welding station is the defining component. Here, the high-frequency current fuses the steel edges together to form a continuous longitudinal seam. This welding method is efficient and creates a clean, strong bond. Following the weld, the pipe undergoes several post-process operations. These include flash removal to clean the weld bead, cooling to normalize the material properties, and sizing to ensure the pipe meets exact dimensional standards for outer diameter and roundness.
A flying cutoff saw cuts the continuously moving pipe to the required length, after which the finished pipes are often straightened and collected on a run-out table. The entire pipe mill is controlled from a central operator station, which monitors speed, welding parameters, and cut-length accuracy.
Shijiazhuang Faith Machinery Co., Ltd. designs these integrated systems to produce a wide array of steel pipes and tubes. The products from an ERW pipe mill are used in numerous applications, including fluid transport, structural frameworks, fencing, and mechanical components. The design philosophy is to offer a coherent and efficient production solution, where each component of the mill is synchronized to convert coiled steel into finished, welded pipe in a single, continuous operation.
