Brief introduction of ERW high precision tube rolling mill

HG series high precision straight seam welded pipe production line is used to produce welded steel pipe from 7mm-508mm in diameter and 0.4 mm-20mm in wall thickness. It can also produce special-shaped tubes, such as square tubes, rectangular tubes, elliptical tubes, etc. within the scope of processing circular tubes. ERW pipe production line is a product with advanced technical characteristics. This unit adopts the most advanced FFX and FF forming system in the world, and chooses German COPRA rolling forming design software as the means and final verification of the design guide roll. The unit has formed the advantages of stable, high quality steel surface, easy to change specifications, advanced technology, reliable equipment and perfect production process.
