Specifications

 Commodity:ERW 610 steel pipe making machine

I. Summary

HG 610 ERW pipe making machine is designed to produce welded pipes of Φ219mm-Φ610mm and6.0mm-19.0mm in wall thickness, as well as corresponding square (480mm×480mm) & rectangle (600mm×360mm) tubes. After we absorbed advanced pipe making technology home and abroad, our innovative production line and each single unit of the production line are not only economical but also practical. The complete production line adopts ZTF technology developed by our company when producing circle pipe. By means of ZTF technology, the customer shall reduce 60% expense on tooling and improve production effiency and create more economic benefit.
