The buried pipeline anticorrosion tape strengthen practice pipeline anticorrosive tape level has many kinds, according to the SY/T0414-2007 standard, strengthen the anticorrosive coating of buried pipeline, anticorrosive tape thickness and structure has been used to determine the coating thickness of 1.0mm. It is suggested that the specific practice is as follows:
1, polyethylene tape respectively by 0.5mm or 0.6mm internal and external zone of the winding side, there are two layers to finish coating thickness of 1.0mm strengthened.
2, polyethylene tape with 0.5mm or 0.6mm (with) anticorrosive belt with 50~55% lap around to form a two layer with thickness of 1.0mm strengthened.
Polypropylene fiber anticorrosive adhesive tape or one of the 3, the PE coating thickness more than 1.0mm with winding side forming strengthen, so more saving material and labor.
