WG377(DLW1200×12.7-300X300X12.7) Multi-functional Cold Bending Steel Welded Pipe Production Line
Brief introduction of ERW high precision tube rolling mill
DLW1200×12.7 multi-functional cold bending steel welded pipe production line is used to produce square pipes and rectangular pipes which both conform with international standard GB/T6728, as well as welded circular pipes that conform with international standard GB/T3091 and GB/T13793. Steel strip is formed into open pipes in forming device. Pipes are welded into straight-seam ones by high frequency, which are cooled, and then shaped and straightened in sizing device. The circular, square and rectangular pipes with needed size are produced, which meet up to Chinese National Standards.

(5).Production process |
|||
|
Feeding → uncoiling → straightening → clamped for leveling → cutting for butt welding → looping (horizontal accumulator) → forming, welding, cooling and sizing → cutting with flying saw → conveying to roll table →packing → entry of finished products into warehouse |
|||
Production Process
Scroll up → Uncoil → Flattening → End Shear & Butt Welding → Accumulator → Forming → High-frequency induction welding→ Removing external burr → Cooling → Sizing → Cutting → Checking & Collecting → Accessing Warehouse
