    Test

    • One tension test shall be made on a specimen for lots of not more than 50 tubes. Tension tests shall be made on specimens from two tubes for lots of more than 50 tubes
    • One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.
    • One flaring test shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot.
    • Each tube shall be subjected to the hydrostatic test, or, instead of this test, a nondestructive electric test may be used when specified by the client.

     

    Surface quality

    • Cold drawn steel tubes shall be free of scale and suitable for inspection. A slight amount of oxidation is not considered scale.
    • Any special finish requirement shall be subject to agreement between the supplier and the purchaser.

     

    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

    The case is most suitable for hanging by forklift.

    EN10204-3.1 MTC shall be issued

    EN10204-3.2 MTC is as option
