The inner surface of the corroded pipe that passes through the operation is always rough and has a hindrance effect on the fluid. The greater the roughness of the pipe wall, the smaller the transmission capacity of the pipe. The protective layer on the inside of the pipe can prevent corrosion, prolong the service life, and reduce the roughness and wear resistance of the inner wall, thereby improving the transportation efficiency.
(1) The protective layer of the pipeline can extend the service life by 20-50 years
(2) Improve the transmission factor and improve the transportation efficiency by 10-25%.
(3) Save energy consumption by 13-30%, increase the distance between pressurized stations by 33%, reduce the number of pressurized stations by 20%, and save a lot of construction funds.
(4) The surface roughness of steel pipe production in China is 25μ. After 6 months of placement, the surface roughness is 50μ, or even 100μ
The surface roughness of the inner protective layer can reach 10μ. As a result, the conveying efficiency can be greatly improved, and the coating cost can be recovered in the same year.
(5) In-situ repair of old pipelines, especially cast iron pipelines for urban water supply and gas supply, can eliminate the phenomenon of "running, rising, dripping and leaking" caused by corrosion perforation, cracks of seals at pipeline interfaces (blue lead, asbestos cement, rubber, etc.), pipeline sand holes, etc., save maintenance expenses and prevent hidden dangers.
