Saigao API 5CT C95 Seamless Steel Casing Pipe

Oil casing is the lifeline to maintain oil well operation. Due to different geological conditions, the downhole stress state is complex, and the comprehensive action of tensile, compressive, bending and torsional stresses acts on the pipe body, which puts forward higher requirements for the quality of the casing itself. Once the casing itself is damaged for some reason, the production of the whole well may be reduced or even discarded.

Saigao API 5CT  C95 Casing Tubing Features

· The surface of thread of coupling and Saigao API 5CT  C95 Casing Tubing should be smooth without any tear, burr or other defects that may have a negative impact on the strength and close connection.

· Saigao API 5CT  C95 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%.

· 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 Saigao API 5CT  C95 Casing Tubing coupling.
