Ultrasonic Testing (UT):
Conduct ultrasonic tests to detect internal defects, including wall thickness variations, voids, or laminations.
Eddy Current Testing:
Use eddy current testing to identify surface and near-surface defects, particularly in non-magnetic materials.
Magnetic Particle Inspection (MPI):
Detect surface and near-surface defects such as cracks using magnetic particle inspection.
Hydrostatic Testing:
Perform a hydrostatic pressure test to verify the casing's resistance to internal pressure. This helps identify leaks or weaknesses in the material.
Mechanical Property Testing:
Verify that the casing meets the specified mechanical properties such as yield strength, tensile strength, and elongation.
Hardness Testing:
Conduct hardness tests to ensure that the material hardness falls within the specified range.
Non-Destructive Testing (NDT):
Employ additional non-destructive testing methods, if required by the specific API 5CT casing grade or customer specifications.
Marking and Documentation:
Verify that the casing is marked with the necessary information, including size, grade, heat number, and any other required markings. Ensure proper documentation of inspection results.
It's important to note that inspection procedures may vary based on the specific requirements of the well, the grade of casing used, and any additional customer specifications. The inspection process should align with the API 5CT standard and any relevant industry or regulatory requirements.
