API 5CT tubing is a pipe that transports crude and natural gas from the hydrocarbon zone to the pipe on the earth surface after drilling. This type of seamless oil pipe is used for withstanding the pressure generated in exploitation process. The outer diameter of the tubing ranges from 60.3 mm to 114.3 mm. Jiangyin Changjiang Steel Tube Making Factory is a leading supplier and exporter of seamless steel tubes and various special pipes. JST API 5CT tubing adopts three-roll micro-tension sizing mill, six roller straightening machine and other advanced equipment to ensure our seamless oil pipes with thick pipe wall, high dimension precision, excellent mechanical property and good process performance. There are mainly three end finish methods or end processing methods for API 5CT tubing, including non-upset threaded and coupled, external upset threaded and coupled, and plain end or flat end.


This kind of seamless oil pipe is mainly used in oil well for extracting petroleum and natural gas.

1. Extracting Oil and Gas

After drilling an oil well and fixing it, place API 5CT tubing in the oil-string casing so as to extract oil and gas to the ground.

2. Water Injection

When the downhole pressure is not enough, it is necessary to use seamless oil pipes to inject water into the well.

3. Steam Injection

In the heavy oil thermal recovery process, we often use insulated API 5CT tubing to inject steam to the downhole.

4. Acidification and FracturingIn order to improve the production of oil and gas wells, we need to transport acidulated and fractured media or condensate to the hydrocarbon reservoir (hydrocarbon zone). This process is finished through seamless oil pipes.


Our API 5CT tubings have gained API SPEC 5CT, API SPEC 5B and ISO11960 certifications.
