High Frequency Welding ERW660 Black Steel Pipe Machinery Diameter 325-660mm API Tube Mill

Product Details

ERW660 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 325mm - 660mm in OD and 6.0mm - 20mm 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

Scroll up→ Uncoiler→ Straightening end→ Flattener→ Auto-Shear and Welding→ Horizontal Accumulator→ Strip UT→Forming(ZTF) → H.F. induction welding→ Removing external burr→ Removing inner burr→ Burnishing→ Online Detection→ Seam annealer→ Air cooling→ Water cooling→ Sizing→ Cut off→ Roll table→Flattening Test→ End-facing and chamfering→ Hydrostatic test→Off-line UT test→ Drifter→ inspection→Weighing and length measurement → Coating & Printing→ 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:

√ Apply to high strength steel and big thickness

√ Raw material can be steel coil and single plate

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

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