Low Carbon Steel Api Tube Mills

Description

The whole production line adopts "ZTF forming technology which is developed by ourselves combined with advanced Japanese FFXtechnology. ( lt is no need to change rollers in the breakdown section) API tube mill is specialized for manufacturing welded tubes 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

√ When producing round pipe, it can utilize ZTF forming technique

√ When producing square & rectangular tube, it can utilize directly square-square (DSS) technique

 Product Parameter

Application

Widely used as the architectural structure tubes, low-pressure liquid tubes, coal transmission belt tubes, driveshaft tubes, guardrail tubes, tower footing tubes, automobile beam steel tubes, and other products.
