Product Description

HF ERW720 Large Diameter Carbon Steel Pipe Machine for Petroleum and Gas API Tube Mill

 

 

Product Details

 

ERW720 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 355mm - 720mm in OD and 6.0mm - 22.0mm in wall thickness, as well as corresponding square and rectangular pipe. Within suitable range of pipe diameter and wall thickness, pipe production speed can be adjusted.

 

Usage and Technology

 

API pipe mill is specialized for manufacturing straight welded pipe for petroleum and gas pipelines. Taking hot-rolled steel as raw material, it produce required pipes through cold roll forming and suitable welding methods like H.F. welding, submerged arc welding and so on. The whole production line adopts ‘ZTF’ forming technology.

 

Technical Flow

 

Scrolling up→ Uncoiling → Shear and Welding→ Spiral accumulator→ Forming → H.F. induction welding→ External burr removing→ Cooling → Sizing→ Flying saw → Run out table →Inspecting→ Packing→ Warehouse

Forming process

 

Round pipe Cold roll forming process Good roller design
ZTF forming process Save alt least 60% roller cost with electric control adjustment
Square & rectangular tube General round-to-square process Stable forming process
Round-to-square with Turks head Good pipe quality
Process of directly square-to-square(DSS) One set of roller can produce all tubes with electric control and automatic adjustment 

 

Equipment Advantages:

 

China's largest straight seam welded pipe production line

Apply to high strength steel and big thickness

Raw material can be steel coil and single plate

 It can utilize ZTF forming technique
