API 5CT C90 CASING

API 5CT C90 Casing Tubing serves to transport both crude oil and natural gas from oil and gas layer to the surface pipeline after drilling is completed. It is able to bear the pressure produced by the exploitation process. After the outer surface is coated with a protective layer, the tubing is marked in accordance with the API 5CT standard and strapped with metal belt.

Available Sizes: 2 3/8″, 2 7/8″ and 3 ½” Outer Diameter

Grades: J55, J55-FBNAU, N80, L80, P110

API 5CT C90 Casing Tubing Features

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.
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.
Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT C90 Casing Tubing coupling.

Grade C90 Oil Well Drilling Tube in different shapes and sizes available.
