API Pipe Mill/Tube Mill

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)

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.

Equipment Advantages

√ Successfully manufactured China's largest straight seam API tube production line with Max OD 720mm

√ Apply to high strength steel and big thickness

√ ZTF forming process save roller up to 60%

√ Electric control and automatic adjustment, high precision,high roller change speed
