Problems solved by technology

[0005] At present, most of the anticorrosion of the inner wall of the pressure steel pipe of the hydropower station is painted with anticorrosion paint, which is difficult to withstand the long-term erosion and corrosion of the water flow, resulting in premature damage to the anticorrosion layer
Due to the long pressure steel pipe, especially the high slope and slope of the inclined pipe section, it is more difficult to erect the overall anti-corrosion inner wall scaffolding. Due to the inclined design of the inclined pipe section of the penstock steel pipe, when the inner anti-corrosion scaffold is erected, the scaffold pole must be welded to the pipeline. The lower side of the inner wall can play the role of supporting the scaffolding. When the scaffolding is removed after the internal anticorrosion is completed, it will take a lot of time to repair the anticorrosion layer at the welding point, so that the construction period of the internal anticorrosion will be delayed several times.
