Test

  • One flattening test shall be made on specimens from each of two tubes from each lot or fraction thereof.
  • One flaring test shall be made on specimens from each of two tubes from each lot or fraction thereof.
  • For tension and hardness tests, the term lot applies to all tubes prior to cutting, of the same nominal diameter and wall thickness that are produced from the same heat of steel.

 

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
