Forming machine is the key equipment of the spiral welded pipe production line, through three-roller plate bending machine, steel strips continuously became spiral tube blanks, and then welded them into spiral pipe through one-side welding, both-side welding or high frequency welding.
The process flow of the production line:
Loading coil → Uncoiling → End straightening and feeding → Five-roll flattening → End cutting and butt welding → Disc edge cutting → Strip surface cleaning → Finish edge milling → Conveying → Pre-bending → Guide board device → Forming → Inner welding → Outer welding (Inner and outer welding seam automatic tracking system) →Sizing → Ultrasonic testing on line → Centralized guide → Pipe cutting → X-ray testing → End facing and chamfering → Hydrostatic testing → Repair welding → Weighing and measuring → Antisepticising → Mark spraying → Storage
We have many models spiral welded pipe production lines. The produced spiral welded pipes satisfied API-5L, GB9711.1-1997, SY/T5037-2000 standards and other related. They could be used for oil and natural gas pipeline, low-pressure water pipe, city gas pipeline, thermal electric power network, urban construction pile pipe, industrial structure tube and so on, to meet the needs of various industries and the needs of different occasions.
