API TUBING
Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading api tubing manufacturer and supplier
API Tubing is a critical tubing material specifically designed for the oil and gas industry, primarily used to transport extracted oil and gas from underground wells to the surface. The design of API Tubing not only prioritizes strength and durability but also emphasizes ease of installation. Our products are manufactured using high-quality steel, offering exceptional corrosion resistance and mechanical strength, capable of withstanding high-temperature and high-pressure operational conditions. The tubing is equipped with standardized connectors, enabling quick installation and disassembly, thereby reducing construction time and costs. Each API Tubing is subjected to rigorous quality inspections, meeting the stringent standards set by the American Petroleum Institute (API), ensuring its reliability and safety under high-pressure and extreme environmental conditions.
The most common application involves running API 5CT tubing strings into oil and gas wells to facilitate the flow of crude oil and natural gas from the producing formation to the surface.
In enhanced oil recovery (EOR) operations, API tubing is used to inject fluids like water, steam, or chemicals into the reservoir to increase pressure and improve hydrocarbon recovery.
Tubing is an integral part of well completion, providing a conduit for various downhole tools and equipment used in the wellbore.
During workover operations, API tubing can be used for tasks such as well servicing, repair, and stimulation treatments.
In gas lift operations, tubing is used to inject gas into the wellbore to lighten the fluid column and assist in bringing hydrocarbons to the surface.
Tubing provides a stable pathway for deploying and retrieving various downhole equipment and instruments, including packers, subsurface safety valves, and production logging tools.
As a leading manufacturer and supplier of API Tubing products in China, our products cover most application scenarios in terms of size and standards. Our products strictly comply with international standards such as API and ASTM. If you have any other requirements for product specifications, please feel free to contact us for customization.
| Size and Dimensions | API tubing sizes are standardized, with common sizes including 2-3/8″, 2-7/8″, 3-1/2″, and 4-1/2″. The outside diameter (OD), wall thickness, and weight of the tubing are specified, along with the dimensions of the couplings. |
| Material and Grade | API tubing is made from various steel grades (e.g., J55, K55, N80, L80, P110) with specific mechanical properties. |
| Connections | Tubing connections, such as Non-Upset (NU), External Upset (EU), and Integral Joint (IJ), are designed to meet specific requirements for sealing and strength. |
| Length | Tubing is typically available in Range 1 (6.10-7.32 m) and Range 2 (8.53-9.75 m) lengths. |
| Testing and Quality Control | API standards also cover testing procedures, including hydrostatic testing and non-destructive testing (NDT), to ensure the tubing’s integrity. |
