Advantages of Our Tubing Pipe

High tensile strength: Reliable support for self-weight, downhole equipment, and production loads, suitable for long-reach and horizontal wells.

Pressure integrity: Designed to safely contain high internal pressures during continuous production from the reservoir.

Corrosion resistance: Available in corrosion-resistant grades such as L80-13Cr for wells containing H₂S and CO₂.

Secure sealing performance: Precision-machined threads and premium connections reduce leakage risk and ensure production efficiency and environmental safety.

Tubing Pipe Specifications

Tubing pipes are manufactured in accordance with API 5CT dimensional requirements. Standard tubing is available with Non-Upset (NUE), External Upset (EUE), and Integral Joint (IJ) connections.


Dimensions, wall thickness, linear mass, and inside diameter vary depending on the outer diameter, weight class, and connection type, ensuring compatibility with drilling and completion equipment.


Main Application Areas for Tubing Pipe

Hydrocarbon production: Serves as the primary flow path to transport oil and gas from the producing formation to the surface.

Casing protection: Isolates the production casing from corrosive well fluids and mechanical damage during production.

Artificial lift systems: Acts as the installation string for pumps, gas lift valves, and other downhole equipment.

Well intervention: Provides controlled access for operations such as acidizing, stimulation, and well servicing
