Features
RT273 Welded Pipe Mill Line is to produce round tube diameter of 165-273mm and wall thickness of 4.0-10.0mm.
We can also supply the customized machines.
RT273 Welded Pipe Mill Line is a series of machines that builds longitudinal weld seam pipe with steel strips of certain width. It starts by uncoil and flatten the slit steel coils into steel strips. The flattened steel strips will 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 (round/ square/ rectangle etc) or size in a sizing machine. Finally the pipe will be cut to length and bundled.
