Since the mechanical properties of API 5CT N80 seamless casing tubing are higher than those of J55 and K55, it may only be used for some difficult development. Because the downhole depth of API 5CT N80 seamless casing tubing is deeper than that of J55 and K55, it is easy to be related to the misuse of center size oil and gas. Due to the large capacity of API 5CT N80 seamless casing tubing, those API-5CT packaging channels are comprehensively connected in gaseous petrol just as coal bed methane extraction, and geothermal wells.

API 5CT N80 seamless casing tubing mechanical properties

API 5CT N80 seamless casing tubing features:
1, The surface of thread of coupling and API 5CT N80 seamless casing tubing should be smooth without any tear, burr or other defects that may have a negative impact on the strength and close connection.
2, API 5CT N80 seamless 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%.
3, Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT N80 seamless casing tubing coupling.
4, Any deformation such as crease, separation, hairline, 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.
