SCH 160 ASTM A/SA268 TP430 Seamless U Fin Tube Stainless Steel For Heat Exchanger
U Bend Tube are manufactured in our plant as per the customer
requirements. Solution annealing after bend will be process to
lower the risidual stress, and followed by hydrostatic testing and
dye penetrant testing if required.
U Bend Tube OD in mm can be bent upon agreement: 15.8 16.0 17.0 18.0 19.05 20.0 21.3 25.4 26.7 31.8 32.0 38.1mm
U bend Tube Initial Length
Maximum lengths of 27000mm can be supplied on request
U bend Pipe Bending radius
Minimum: 1.5×OD
Maximum: 1500 mm

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
