API 5CT T95 Seamless Pipe
Tubos India is one of the large manufacturers for high quality API 5CT T95 Casing Pipes. API 5CT T95 Casing Tubing used for transport both crude oil and natural gas from oil and gas layer to the surface pipeline after drilling is completed. It has the ablility to bear the pressure produced by the exploitation process. Our oilfield tubing & API 5CT Grade T95 Casing Pipe can be widely applicable to construction, petroleum, smelting, shipbuilding, aviation, food, electric power, paper, medical equipment, chemical industry, boilers, heat exchangers, metallurgy.
T95 Casing is placed downhole to provide structural integrity to the wellbore and must withstand external collapse pressure from rock formation and internal yield pressure from gases and fluids. It also must hold its own deadweight and withstand the transaxial pressure and torque placed on it while running downhole.

Api T95 Seamless 5CT Petroleum Casing Pipe high quality material.
Inspection
Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:
- Straightness
- Dimensions
- Weights
- Lengths
Part of this inspection is to drift all lengths.
Despite all the American Petroleum Institute (API) specifications and testing, some tubing defects are still found after delivery; thus, some operators do further inspection.
Inspection Method
- Size and surface inspection
- NDT and pressure test and third party certication
- Electromagnetic
- Magnetic particle
- Physical and chemical analysis
- Hydrostatic
- Drifting test
- Hardness and pressure test.
- Ultrasonic

API 5CT T95 Casing Tubing Features
- API 5CT T95 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%.
- Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT T95 Casing Tubing coupling.
- The surface of thread of coupling and API 5CT T95 Casing Tubing 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.
