Stainless Steel 316 U Bend Tube Tolerance

Dimensional tolerances U tube acc. to TEMA R.C.B.

1). Length of straight part -0/+5 mm 
Flattening (also called “ovality”) at the bend shall not exceed 10% of the nominal tube outside diameter.
Wall thickness in bending part acc. to TEMA R.C.B 2.31

2). Minimum tube wall thickness in the bend part (T min)T(min) ≥ (SW × (2×R + D))/( 2× (R+D) 
where: SW is smallest wall thickness
D Nominal outside diameter
R radius 

3). Radius tolerance 
1) for R 100 mm +/- 3 mm
2) for R ≥ 100 mm +/- 5 mm

4). Straightness tolerance max. 1,5 mm per 1 m
U-Tube ends: plain, vertically cut to the tube axis
