Tubos India is one of the large manufacturers for high quality API 5CT Q125 Casing Pipes. API 5CT Q125 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 Q125 Casing Pipe can be widely applicable to construction, petroleum, smelting, shipbuilding, aviation, food, electric power, paper, medical equipment, chemical industry, boilers, heat exchangers, metallurgy.
Q125 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 5CT Grade Q125 Oil Well Drilling Casing Pipes are comparatively low steel grade.
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:
- Dimensions
- Lengths
- Straightness
- Weights
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
- Magnetic particle
- Hardness and pressure test.
- Electromagnetic
- Hydrostatic
- Drifting test
- NDT and pressure test and third party certication
- Physical and chemical analysis
- Ultrasonic

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