< br / >



considering tap water pipeline anticorrosive coating work environment, have buried pipe, bridge, tunnel across a variety of categories, such as polyethylene tape coating work conditions vary.



< br / >



may bring different effect on coating performance:



< br / >



1, the buried pipeline covering soil layer, blocking the light, to a certain extent reduce the polyethylene anticorrosive tape coating ultraviolet aging tendency, but the soil water content is high, the anticorrosive coating immersion resistance requires serious;



< br / >



2, pipeline bridge, completely exposed to the atmosphere, polyethylene anticorrosive tape coating environment is relatively dry, anticorrosive coating immersion resistance requirement is not high, but resistance to ultraviolet radiation aging demanding;



< br / >



3, the tunnel pipeline in direct sunlight in the shade, environment humidity, tube slightly higher than the bridge, anticorrosive coating work environment between the former two.



< br / >



4, in addition, according to the experience of the pipeline construction, the construction technology of anticorrosive coating: manual or mechanical winding winding, and about the quality of the polyethylene anticorrosive tape coating anticorrosive effect is also nots allow to ignore.
