Commodity: ERW steel tube mill
Zhongtai pipe production line is designed to manufacture pipe or tube used in metallurgy,
construction, transportation, machinery and vehicle industries. It makes pipe or tube of carbon
steel strip by ZTF technology, which is developed by our company on basis of the world advanced forming technology as well as our former technology and skills. 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 when producing round pipe,
the customer shall reduce 60% expense on tooling and improve production effiency and
gain maximum economic benefit.
