Carbon Steel Pipe Welded Machine

I. Description of tube mill

Tube mills produce pipe and tube by taking a continuous strip of material and continuously rollforming until the edges of the strip meet together at a weld station. At this point the welding process melts and fuses the edges of the tube together and the material exits the weld station as welded tube.

The welded pipe making machine, also called welding pipe making machine or pipe making machine, is used to produce different types of products, such as round types, square types, and rectangular types. The equipments use roll pass design, so the production line can produce welded steel pipes which has the feature of good quality machining and precision assembling.Our World Technology Machinery Company is expertise to producing the welded pipe making machine, therefore, different diameter and wall thickness are available. At the same time, we can design and produce products in accordance with clients’ requirements.
