API pipe production line
This production line is mainly used for making round, square, rectangular and other shapes of steel pipes.
Brief introduction
This welded pipe production line is designed to produce welded pipes with O.D. 219-508mm and thickness 6.0-18mm, as well as corresponding square and rectangular pipes.
Working flow
Uncoiling→ flattening →shear and butt welding → cage accumulator → strip→ trimming → roll forming →high frequency welding → removing burrs(inside and outside) → I.F. annealing→ air and water cooling → sizing → pipe ultrasonic detect→flying saw→ flattening test→ end beveler → hydrostatic test→ conveying → downloading→ appearance→marking→packing→warehousing.
