Suitable for use in harsh oilfield environments, it is applied to the rehabilitation and renewal of oil, water supply, heating and gas pipelines with a diameter range of φ60 to φ500 and an operating temperature of -22°F to 176°F..

High temperature and corrosion resistance; capable of withstanding negative pressure; high requirement for the cleanliness of the original pipeline inner wall; passable through 3D elbows; the continuous rehabilitation length of a single repair section can reach 500 meters; the universal expansion coefficient ensures no delamination or fracture after rehabilitation.

Only two working pits are needed for a single repair section; low demand for large-scale machinery and equipment.

Structure & Rehabilitation Technology of Reversed Composite Hose

Reversed Lining Rehabilitation Technology

• The reversed composite hose is everted and attached to the inner wall of the pipe section to be repaired. After hours of curing, the reversed composite hose will integrate with the pipe to be repaired, and the original pressure, flow rate and other parameters can be maintained after rehabilitation.

• Capable of withstanding the same negative pressure as the original pipeline.

• Reduces costs by more than 30%.

• Shortens the construction period to about 40% of the traditional process.
