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
- Straightness
- Weights
- 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
- Drifting test
- NDT and pressure test and third party certication
- Hydrostatic
- Electromagnetic
- Physical and chemical analysis
- Hardness and pressure test.
- Magnetic particle
- Ultrasonic

API 5CT C90 Casing Tubing Features
- Any deformation such as hairline, separation, crease, crack or scab is not acceptable on both inner and outer surfaces of the product. All these defects should be completely removed and the removed depth must not exceed 12.5% of nominal wall thickness.
- API 5CT C90 Casing Tubing is offered with a free length range from 8m to 13m on basis of the SY/T6194-96 norm. However, it is also available no less than 6m length and its quantity should be no more than 20%.
- The surface of thread of coupling and API 5CT C90 Casing Tubing should be smooth without any tear, burr or other defects that may have a negative impact on the strength and close connection.
- Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT C90 Casing Tubing coupling.
