Flaring Test (Seamless Tubes)

One test shall be made on specimens from one end of one tube from each lot of finished tubes.

Flange Test (Welded Tubes)

One test shall be made on specimens from one end of one tube from each lot of finished tubes.

Hardness Test

Brinell or Rockwell hardness determination shall be made on specimens from two tubes from each lot. 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. When final heat treatment is in a batch-type furnace, a lot shall include only those tubes of the same size and the same heat which are heat treated in the same furnace charge. When the final heat treatment is in a continuous furnace or when the heat-treated condition is obtained directly by quenching after hot forming, a lot shall include all tubes of the same size and heat, heat treated in the same furnace at the same temperature, time at heat, and furnace speed, or all tubes of the same size and heat, hot formed and quenched in the same production run.

Reverse flattening Test

For welded tubes, one reverse flattening test shall be made on a specimen from each 1500ft(460m) of finished tubing. Coiled tubing greater than 1500ft(450m) in length shall be sampled at both ends, a coil must be continuous without any circumferential butt welds.

Hydrostatic or Nondestructive Testing

Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test.

Instrumentation tubing Markings and Packing

  • Markings will adhere to prescribed specifications in A1016/A 1016M and shall include whether the tubing is seamless or welded and the final heat-treatment temperature in digress Fahrenheit after the suffix” if the final heat treatment temperature is under 1900°F (1040°C).
  • When the nondestructive electric test is performed, each length of tubing shall be marked with the letters “NDE” and the certification, when required, shall also indicate this test.

Note:

  • Mill test certificates will be issued according to EN10204.3.
  • All tubes shall be supplied as per applicable ASTM A269 Specification.
