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
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
