API 5CT C95 Casing Pipe|Olifield Casing Pipe

 

We have the ability to detect the whole process. We can fully guarantee the high quality of the products.

 

It is well known that oil casing is the important lifeline for maintaining oil wells' operation. But geographical environment is totally different in different areas and the connection of underground force is very complex. A variety of forces acting on the pipeline together, for example: tension, pressure, bending and twisting stress, all of which require oil casing should reach a higher level of quality. Oil casing's damage for some reason will cause the oil wells' production decline; some time seriously it will make well abandonment. So our company produces L80 steel grade oil casing strictly according to the API 5 CT standards

Inspection

 

Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:

  • Dimensions
  • Weights
  • Straightness
  • Lengths

Part of this inspection is to drift all lengths.
Despite all the American Petroleum Institute (API) specifications and testing, some tubing defects are still found after delivery; thus, some operators do further inspection.

 

Inspection Method
  • Size and surface inspection
  • NDT and pressure test and third party certication
  • Hydrostatic
  • Drifting test
  • Physical and chemicail analysis
  • Hardness and pressure test.
  • Electromagnetic
  • Magnetic particle
  • Ultrasonic
