Bonded coiled tubing for underground use (injection well tubing)

Bonded continuous tubing for underground use is designed to address the severe corrosion of oil and water well tubing in oil fields, and other non-metallic tubing cannot meet the challenges of high temperature, high pressure, and high axial tension in the underground.

The bonded continuous tubing used underground has overall resistance to high internal and external pressure, high temperature resistance, strong axial tension, strong corrosion resistance, no scaling, no wax formation, high construction efficiency, and long service life, which effectively solves the problem of water injection well strings.
