Coiled tubing pipe is the means by which oil and gas are transported from the subsurface reservoir to the surface. Coiled tubing is run inside the production casing string and is subject to the weight of production, corrosive elements like H2S and CO2, and leak tightness. This API 5CT tubing is used to optimize reliability while maximizing your production efforts.

    Detailed Description of Tubing Pipe

    Production tubing is the pipe string which conveys hydrocarbons to surface. It is set in the final casing string, along with the production casing, is the last barrier preventing produced fluids from entering the environment, which is why the integrity of the tubing is critical. The tubing needs to support its weight, any down hole equipment, and dynamic loads while producing, which means it must have adequate tensile strength. The joints (couplings) are the most important part of the tubing string. We stock standard API connections like EUE (External Upset End), which provides higher joint strength, and NUE (Non-Upset End), and specific premium gas-tight connections for high-pressure gas wells.

    Advantages of Our Tubing Pipe

    High tensile strength: Trustworthiness in self-supporting weight and production loads over long or horizontal distances.

    Pressure integrity: Capable of containing high production pressures safely from the reservoir.

    Corrosion resistant: Available in different grades (examples L80-13Cr) to contend with corrosive well environments (H2S, CO2).

    Secure seallng: High-quality-thread connections mitigate leakage to guarantee production efficiency and environmental safety.

    Main Application Areas for Tubing Pipe

    Tubing is used exclusively in the oil and gas completion and production phases to:

    Transport Hydrocarbons: Serve as the main pathway to bring oil and gas from the producing formation to the surface.

    Protect the Casing: Isolates the production casing from corrosive well fluids and damage from production operations.

    Facilitate Artificial Lift: Serves as the string to install downhole equipment such as pumps and gas lift valves.

    Well Intervention: Temporarily section of the entire well to have treatments applied such as acidizing or fracturing in the well.
