High Frequency (HF) longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 8mm to 89mm in OD and with a maximum wall thickness of 4.5mm, as well as corresponding square and rectangular pipe.
This production line is a comprehensive complete production line for continuous welding of steel strips into pipes, the strip steel is unrolled by the uncoiler, and then enters the accumulator storage after passing through the shear butt welding machine. The strip steel is extruded by rollers and divided into two parts: break-down section and fine pass section. After high-frequency induction welding and sizing part, output the required length of pipe, cut off by flying saw, and finally stack and pack the steel pipe.
