    TEST CERTIFICATE
    Mill Test Certificate as per EN 10204 / 3.1

    Advanced capabilities for U-bent tubes:

    1. Reliable bending machines
    2. Precision bending dies
    3. Eddy current test before bending
    4. Bending up to 105’(32m) developed length
    5. Electric resistance stress relief annealing after bending
    6. Hydrostatic test after bending
    7. OD and WT reduction Testing
    8. Full bending radius and tube legs tolerance check
    9. Stack-rack boxing

    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

    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
