Polypropylene Fiber wrapped around the cold belt，an anticorrosion tape, uses features : preservation of polypropylene fiber tape is a new type of non-polluting, without endangering the environment-friendly anti-corrosion products, and represents the current international and domestic cold preservation tape wrapped around the highest level, "preservative crown" never stops. Can be widely used in oil, gas, petrochemicals, construction of urban water supply and drainage, gas, steel gas pipe and steel storage tank buried outside the preservation and restoration project. Construction of the country, the Environmental Protection Agency designated alternative "Asphalt glass fiber cloth," "The epoxy coal tar" on the recommendation of products. Construction is simple, impact, aging resistance, tensile resistance, resistance to ultraviolet radiation, higher bond strength characteristics. The product of a unique substrate Polypropylene woven fiber cloth used butyl rubber modified asphalt preservation Recessed. Its fiber structure of the substrate can effectively resist stress due to soil creep arising from the destruction, After aging test to prove their corrosion life of 50 years or more. Detection of the various indicators considerably higher than SY/T0414-98 standards. fully achieved and the United States ANSI/AWWAC209-00 NACEMR0274-95 index. Cold preservation is a pipeline construction tape the best choice and anti-corrosion most economic choice.
