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.
