English
A petroleum pipe coupling is a short section used to connect oil casing or tubing, typically cylindrical with internal threads to ensure a tight connection.
OCTG Couplings enhance the strength of pipe connections, provide excellent sealing to prevent leaks, and withstand high-pressure and high-temperature environments, ensuring the safety and efficiency of oil and gas extraction and transportation.
Couplings are manufactured to meet industry standards (e.g., API specifications) for thread dimensions, tolerances, and performance, ensuring compatibility and reliability.
Couplings are short, threaded components that connect casing or tubing joints. They have internal threads matching the external threads of the pipe ends.
Couplings create a tight seal to prevent fluid leakage. Thread compounds or sealants are often used to enhance sealing efficiency.
Couplings transfer axial loads and torsional forces between connected sections, ensuring structural integrity under downhole pressures and stresses.
They help maintain proper alignment of the casing or tubing string, reducing bending stresses and ensuring smooth operation during installation and extraction.
Made from high-strength materials like steel alloys, couplings are designed to resist corrosion, wear, and mechanical failure in harsh downhole conditions.
Casing Coupling Common Applications
Casing couplings in the oil and gas industry connect casing pipes, providing structural support for wellbores. They enable zonal isolation, contain pressure, and protect the wellbore wall from erosion and collapse.
Tubing Coupling Common Applications
Tubing couplings connect tubing for fluid transportation in wells. They assemble the production string, aid in well intervention and maintenance, and can be adapted to different well conditions like high temperature or corrosion.
