Bending Methods For TP304 Stainless Steel Pipe

Cold Bending
  • Rotary draw bending over a mandrel
  • Suits small and medium bore pipe
  • Mandrel support protects thin walls (Sch 5S, 10S)
  • Tooling allows for springback
VS
Hot / Induction Bending
  • Local induction heating, then bending
  • Suits large bore and heavy wall pipe
  • Solution anneal and pickle after hot bending
  • Restores corrosion resistance at the bend
