API Pipe Mill/Tube Mill

API tube mill is specialized for manufacturing welded tube for petroleum and gas tube lines. Taking hot-rolled steel as raw material, it produces required tubes through cold roll forming and suitable welding methods like H.F. welding, submerged arc welding and so on.

Description

The whole production line adopts "ZTF" forming technology which is developed by ourselves combined with advanced Japanese FFX technology. ( It is no need to change rollers in breakdown section)
