Polyethylene anticorrosion tape, also known as: tape wrapped around the cold, corrosion tape, anticorrosive tape polyethylene, butyl rubber, anti-corrosion tape, anticorrosive tape compound, GF-92 co-extruded composite corrosion heat tape, adhesive tape with corrosion is mainly used in petroleum, natural gas transmission; chemical industry, urban construction, water supply and drainage, and gas transportation pipelines and other buried steel outer surface corrosion. With easy construction, no pollution, is the preferred pipeline corrosion systems outside of corrosion. 
 Tape can be divided into general use by function: anti-corrosion zone (inner zone), the protection zone (outer) and the mending tape. Tube is butyl rubber, has excellent resistance to aging, sealing and insulating effect. The products in full compliance with the performance indicators and the art of oil SY/T0414-2007 Association ANSI/AWWAC209-00 and NACEMR0274-95 standard. Reached the advanced level of similar products at home and abroad. 
 1, the layer thickness and adhesive seal. 
 2, substrate and layer combination of force, the store does not exist in the construction process or degumming phenomenon. Get the latest information on the concrete landing 
 3, good heat aging, anti-UV capability. 
 4, high tensile strength, elongation at break due to facilitate mechanized and manual winding. 
 5, species, size, full color, including the preservation zone (the zone), the protection zone (outer), mending tape, anti-corrosion primer and construction machinery and so on.
