API 5CT J55 Petroleum Casing Pipe|Olifield Casing Pipe

 

The J55 API-5CT casing pipe is a comparatively low steel grade in oil drilling. It is widely applied for shallow oil and gas extraction.

Because of  its low cost among other grades of steel, it enjoys wider applications,  can be generally used in shallow wells, geothermal wells, and water wells.

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
