Programming interface 5CT P110 Casing Tubing is an API 5CT Oil Casing Pipe and predominantly utilized for oil well boring. We produce API 5CT P110 Casing Tubing as per the SY/T6194-96 standard, it is accessible as short string sort and long string sort provided with their couplings. As indicated by American Petroleum Institute Standard API SPEC 5CT1988 first release, the steel evaluation of API 5CT oil packaging channel can be separated into ten sorts, including H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110 and Q-125. We supply the packaging funnel and Grade P110 Oil Well Drilling Casing Pipe went with string and coupling.

API 5CT P110 Casing Tubing Features

  • Any deformation such as crease, hairline, separation, 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.
  • The surface of thread of coupling and API 5CT P110 Casing Tubing should be smooth without any burr, tear or other defects that may have a negative impact on the strength and close connection.
  • Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT P110 Casing Tubing coupling.
  • API 5CT P110 Casing Tubing is offered with a free length range from 8 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%.

It's important for oil and gas operators to protect their production well casings from corrosion with cathodic protection & API 5CT P110 OilField Tubing primarily serves to transfer oil and gases.
