Programming interface 5CT Q125 Casing is an API 5CT Oil Casing Pipe and basically utilized for oil well boring. We fabricate API 5CT Q125 Casing 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 funnel can be partitioned into ten kinds, 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 API 5CT Q125 Casing went with string and coupling.

Programming interface Q125 Oil And Gas Api Casing Pipe serves to transport both raw petroleum and flammable gas from oil and gas layer to the surface pipeline in the wake of penetrating is finished. It can hold up under the weight delivered by the misuse procedure. After the external surface is covered with a defensive layer, the tubing is set apart as per the API 5CT standard and tied with metal belt. Our oilfield tubing and Grade Q125 Oil Well Drilling Casing Pipe can be generally appropriate to oil, development, shipbuilding, purifying, flying, electric power, nourishment, paper, synthetic industry, restorative hardware, boilers, heat exchangers, metallurgy, etc.

API 5CT Q125 Casing Tubing Features

  • The surface of thread of coupling and API 5CT Q125 Casing should be smooth without any burr, tear or other defects that may have a negative impact on the strength and close connection.
  • 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.
  • Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT Q125 Casing coupling.
  • API 5CT Q125 Casing 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%.

API 5CT Q125 OilField Tubing primarily serves to transfer oil and gases & it's important for oil and gas operators to protect their production well casings from corrosion with cathodic protection.
