Rehabilitation of water supply pipesThe main methods are as follows:
Mechanical external force repair: This method is mainly through the use of mechanical devices to clean, dredge and repair the pipeline. These include high-pressure cleaning, high-pressure dredging, and mechanical dredging, among others.
Coating repair: This method is mainly by coating the inner surface of the pipeline with a layer of waterproof, anti-corrosion, anti-rust and other coating materials to protect the pipeline from corrosion, aging and other damages, and at the same time prolong the service life of the pipeline.
Local repair: This method mainly repairs the damage, cracks, corrosion, etc. of the pipeline by using local repair technology. These include grease injection, repair, partial replacement, and more.
Integral repair: This method mainly repairs the entire piping system by adopting the overall repair technology. These include flip lining repair technology, in-situ curing repair technology, etc.
Among them, the flip lining repair technology is to flip a new pipe and stick it to the inner wall of the original pipe, and bond the new pipe with the original pipe by heating, pressurization, etc., to achieve the purpose of repair. This method is suitable for various types of pipeline repair, especially the repair of large-diameter pipelines. The in-situ curing repair technology uses resin materials to form new pipes inside the pipes to repair the damage and corrosion of the original pipes. This method is suitable for various types of pipeline repair, especially the repair of small-diameter pipes.
The above isRehabilitation of water supply pipesDifferent methods are suitable for different pipeline problems and scenarios, and the repair effect also has its own advantages and disadvantages. In practical application, it is necessary to choose the appropriate repair method according to the specific situation.
