API 5CT J55 Stainless Steel Tubing

J55 API Welding Casing Pipe

API 5CT J55 Oil Casing Pipe
Tubos India is one of the large manufacturers for high quality API 5CT J55 Pipes. API 5CT J55 Casing Pipe is comparatively low steel grade in oil drilling. API 5CT J55 Tubes is widely applied for gas extraction and shallow oil. Among all the other grades, API J55 pipe have low cost due to which it is widely used in shallow wells, water wells and geothermal wells. Oilfield tubing & API 5CT Gr. J55 Casing Tubing can be widely applicable to construction, shipbuilding, petroleum, smelting, aviation, food, paper, electric power, medical equipment, boilers, chemical industry, heat exchangers, metallurgy.
Specification includes 1.9 inch(48.3mm), 2 7/8 inch(73.03mm), 2 3/8 inch(60.3mm), 3 1/2 inch(88.9mm), 4 1/2 inch(114.3mm), 4 inch(101.6mm) etc. The oilfield tubing can be classified as EUE type and NUE type. Both sealing performance and mechanical property of the tubing are also required to correspond with the oil casing pipes.

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
- Straightness
- Lengths
- 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
- Drifting test
- Physical and chemical analysis
- NDT and pressure test and third party certication
- Hydrostatic
- Magnetic particle
- Hardness and pressure test.
- Electromagnetic
- Ultrasonic
