Welded Pipes Mills 01
The production of stainless steel welded pipes starts with coils or plates as raw materials. For coils, the process involves uncoiling and slitting into strips, then forming them into round pipe blanks. Welding is carried out using TIG combined with plasma welding. After welding, the pipes undergo on-line solution annealing, with internal weld bead removal, followed by cutting to fixed lengths. Each pipe is subjected to a hydrostatic test, as well as eddy current (ET) and ultrasonic (UT) non-destructive tests, to ensure weld seam and pipe body quality.
For plates, the process begins with slitting and end bevelling, after which welding is performed using Submerged Arc Welding (SAW), MIG welding, or TIG welding to produce large-diameter welded pipes. Finally, the pipes also undergo heat treatment, non-destructive testing, and inspection before delivery.
