    • Tubes shall have a smooth internal and external surface consistent with the cold working process. As a result, the arithmetical mean deviation of the profile Ra, will be 6.3 um or less.
    • Slight surface imperfections such as scabs or gouges, resulting from the manufacturing process are permitted provided the inner and outer diameters, after dressing, continue to meet the specified requirements, Scabs, laps or laminations are not permitted.

    If freedom from imperfections is of particular significance, an appropriate non-destructive test method (such as eddy current or ultrasonic testing) shall be agreed.

    • In compliance with commercial practice, the tubes shall be supplied with provisional corrosion protection. If a particular form of corrosion protection, or non whatsoever, is requested, this shall be stated in the order.


    • The tensile test shall be carried out at ambient temperature.
    • The flattening test shall be carried out, as specified in DIN EN 10233, on annealed and normalized tubes, the wall thickness of which is less than 15% of the outside diameter.

    After testing, the samples shall be inspected for cracks.

    • The drift expanding test shall be conducted as described in DIN EN 10234. After testing, the samples shall be inspected for cracks.
    • The surface roughness shall be measured axially by using electric stylus instruments as specified in DIN 4768

    Tubes shall be delivered with square cut ends. The ends are free of excessive burrs.

    The tubes are bundled in the waterproof plastic sheet and packed in the wooden cases
