  Visual Examination of Coating

  1. Pipe would be free of ovality through out the length of pipe

  2. Pipe inside and outside surface should not have fold, hairline, delamination, crack, rolling

  Defects such as folding, scarring. These defects shall be completely removed, remove depth

  Shall not exceed 12.5% of the nominal wall thickness.

  3. Coupling outside surface should not have fold, hairline, delamination, crack, rolling defects

  Such as folding, scarring.

  4. Casing pipe and coupling thread surface should be smooth, there should be no burr, tear

  And something to make the thread tied to interrupt impact strength and other defects

  Inspection of Physical Properties

  Hydrostatic pressure test, flattening test, sulfide stress corrosion cracking test, hardness

  Testing, Tensile test, transverse impact test, Determination of grain size

  Application and Category

  Oil casing is to maintain the lifeblood of any oil Wells. Due to the different geological

  Conditions, downhole complex stress state, tension, pressure, bending, torsion stress

  Combination on the pipe body, which raised higher requirement about the quality of the

  Casing itself. Once the casing damage itself for some reason, that may lead to the reduction

  Output of the well, or even scrapped.

  ApplicationUsed in o il well drilling. It is m ainly used for drilling process and after

  Completion of borehole wall support, to ensure that the drilling process

  And the whole Wells after completion are normal running.
