API 5CT J55

API 5CT J55

API 5CT J55 casing pipe is a relatively low-grade steel that is used in oil drilling. It is commonly used to extract shallow oil and gas. Due to its cheap cost in comparison to other grades of steel, it has a broader range of uses and may be used in shallow wells, geothermal wells, and water wells.

PRODUCT FEATURES

API 5CT J55 Tubing and Casing Features

  • The threaded surface of the coupling and API 5CT J55 Casing Tubing should be smooth and free of tears, burrs, or other issues that might affect the strength and tightness of the connection.
  • API 5CT J55 Casing Tubing is available in a free length range of 8m to 13m in accordance with the SY/T6194-96 standard. However, it is also available in lengths of up to 6m and in quantities of no more than 20%.
  • No deformation mentioned in the standard is allowed on the outer surface of the API 5CT J55 casing joint.
  • On both the inner and exterior surfaces of the product, any deformation such as a wrinkle, separation, hairline, fracture, or scab is unacceptable. All of these faults should be entirely corrected, with the depth eliminated not exceeding 12.5% of the normal wall thickness.
