Programming interface 5CT N80 oilfield packaging channel contains N80-1 and N80-Q types. Those two materials are totally reliable in regards to the concoction arrangement and mechanical characteristics, they are only different in the warmth treatment. Amid warmth treatment, N80-1 steel is treated by normalizing and hardening, while N80Q steel is treated by extinguishing and treating. In this manner, the crumbling quality and interior weight quality of N80Q are higher than that of N80-1. N80-1 or N80Q ought to be plainly appeared by the creator when N80 packaging is chosen.

As its mechanical properties are higher than J55 and K55 types, it might just be used to certain somewhat more difficult developments. With more profound downhole profundity than J55 and K55 types, it tends to be connected for the misuse of center dimension oil and gas. Because of the high capacity of N80 material, those API-5CT packaging channels are comprehensively connected in gaseous petrol just as coal bed methane extraction, and geothermal wells.

API 5CT N80 Casing Tubing Features

  • Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT N80 Casing Tubing coupling.
  • The surface of thread of coupling and API 5CT N80 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.
  • API 5CT N80 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%.

Offering N80 Gas and Oil Api Casing Pipe of high range and excellent quality as per API 5CT specifications.
