Types of Seamless Oil Tubing:

Non-Upset (NU) Tubing: The pipe ends are not thickened and are directly threaded, with couplings added.

External Upset (EU) Tubing: Both pipe ends are externally thickened, threaded, and equipped with couplings.

Integral Joint (IJ) Tubing: One end is internally thickened with external threads, while the other end is externally thickened with internal threads, allowing direct connection without couplings.

Our seamless oil tubing adheres to rigorous standards, providing reliable solutions for various applications in the oil and gas industry.

Functions of Oil Tubing:

Oil and Gas Extraction: Placed in the oil casing after drilling and cementing, oil tubing is used to extract oil and gas from the reservoir to the surface.

Water Injection: When reservoir pressure is insufficient, oil tubing is employed to inject water into the well.

Steam Injection: In heavy oil recovery processes, insulating oil tubing is used to introduce steam into the well.

Acidizing and Fracturing: For enhanced well productivity or late-stage well treatments, oil tubing transports acids, fracturing media, or solidifying agents.

Steel Grades for Oil Tubing: Our oil tubing is available in various steel grades to meet specific requirements:

H40, J55, N80, L80, C90, T95, P110.

N80-1 and N80Q: While having consistent tensile properties, they differ in delivery conditions and impact performance.

L80-1, L80-9Cr, and L80-13Cr: These variations cater to different purposes, with L80-9Cr and L80-13Cr specifically designed for highly corrosive environments.

Additionally, C90 and T95 are classified into Type 1 and Type 2, each serving distinct purposes.
