Alloy Steel U Bend Tubes

Purpose: Accommodate thermal expansion in shell-and-tube heat exchangers, reducing stress on tubesheet connections.

Bending Process:
- Methods: Cold bending or induction bending.
- Challenges: Minimize wall thinning, ovality, and residual stresses.
- Post-Bending Heat Treatment: Stress relieving (e.g., 650–700°C) to restore properties.
