Dimensional tolerances U Bend Tube acc. to TEMA R.C.B.
1) U Bend Pipe 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) U Bend Tube 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) U Bend Tube Radius tolerance
1) for R 100 mm +/- 3 mm
2) for R ≥ 100 mm +/- 5 mm
4). U bend Pipe Straightness tolerance max. 1,5 mm per 1 m
U Bend Tube ends: plain, vertically cut to the tube axis
