Test

  • One notched bar impact test, consisting of breaking three specimens, shall be made from each heat represented in a heat-treatment load on specimens taken from the finished pipe.
  • For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each lot. When heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipes.
  • Each length of pipe shall be subjected to the hydrostatic test or the nondestructive electric test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.

 

  • Nondestructive Electric Test—Nondestructive electric tests shall be in accordance with Specification A 999/A 999M, with the following addition:

If the test signals were produced by visual imperfections, the pipe may be accepted based on visual examination, provided the imperfection is less than 0.004 in. (0.1 mm) or 12½ % of the specified wall thickness (whichever is greater).

 

Visual imperfections:

      Surface roughness

      Straightener marks

Cutting chips

Steel die stamps

Stop marks, or

Pipe reducer ripple

 

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
