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

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
