Technical conditions:
1.Heat treatment: Stress relive annealing of U-tubes after bending
2.Dimensional tolerances U-tubes acc. to TEMA R.C.B.
3.Length of straight part -0/+5 mm
4.Flattening (also called “ovality”) at the bend shall not exceed 10% of the nominal tube outside diameter.
5.Wall thickness in bending part acc. to TEMA RCB 2.31
6.Minimum tube wall thickness in the bend part (T min)
T(min) ≥ (SW × (2×R + D))/( 2× (R+D)
