We are offering tube mill. The erw (electric resistance welding) pipe mill is a series of machines that builds longitudinal weld seam pipe with steel strips of certain width. It starts by uncoil and flatten the slitted steel coils into steel strips. The flattened steel strips will then be inserted into the forming machine and the rollers in the machine will bend the strip to a round pipe shape. The round pipe will then be sent into the weld box where the tube is welded by a high frequency or solid state welder. The welded pipe will be formed to expected shape or size in a sizing machine. Finally the pipe will be cut to length and bundled.this pipe is used especially for petroleum , natural gas , city gas , pipe network , chemical industry, electricity , steel truss , water and gas pipeline ;it is widely used for a variety of pressure pipelines .
