The application of polyethylene tape in tap water pipes

< 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.
