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.
  • Flaring test (for seamless tubes) shall be made on specimens from one end of one tube from each lot of finished tubes. The minimum expansion of the inside diameter shall be 10%.
  • One test shall be made on specimens from one end of one tube from each lot of finished tubes. The flattening test may be performed instead of the flange test unless the flange test is specified in the purchase order.
  • Each welded tube shall be subjected to either the hydrostatic or nondestructive electric test. The client may specify which test is to be used. Each seamless 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

All tubes shall be free of excessive mill scale, suitable for inspection. A slight amount of oxidation will not be considered as scale. Any special finish requirements shall be subject to agreement between the manufacturer and the clients.

 

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
