LW400 Full Automatic Directly Forming Tube Mill is designed to produce welded square pipes in dimensions 30×30mm to 100×100mm with wall thickness of 1.5mm to 4.5mm. This production line features full automatic direct forming technology, where one set of rollers can produce all sizes of square and rectangular pipes. The entire process is controlled by PLC, representing the most advanced technology in the industry.

• Steel strip is directly rolled and bent into square & rectangle shapes, then welded into finished pipe
• Superior edge shape quality compared to round-to-square forming methods, with smaller inner arc radius and flatter brims
• Lower overall line load, particularly in sizing parts
• Reduced raw material consumption (2.4-3% less steel strip width)
• Combined rollers allow one set to produce all square & rectangular tube specifications
• 80% reduction in roller costs and spare parts inventory
• Automatic size changes via computer-controlled roller position adjustment

As a CE & ISO9001:2008 certified pipe making machine manufacturer, our high-quality, reliable machines with long service life have been exported to nearly 30 countries including Turkey, Egypt, Morocco, Kazakhstan, Mexico, and Vietnam.
