Polypropylene mesh fiber reinforced pipe anti-corrosion tape, which the substrate is a unique woven polypropylene mesh fiber, then coated with a highly viscous but yl rubber modified asphalt anti corrosive layer is formed. This tape is with anti-corrosion technology in recent years, specifically for long-distance pipelines and depots pipeline cathodic protection requirements of the invention, represents the advanced level of international and domestic anti-corrosion tape technology. It has many unique advantages and a more pronounced excellent performance.
