Jining polyethylene wrapped around with a cold, cold wrapped with composite polyethylene anticorrosion adhesive tape 
 Polyethylene gas pipeline anticorrosion adhesive tape 
 China's oil and gas production and city gas pipeline network of corrosion encountered in the vast majority of electrochemical corrosion. Soil corrosion principle belongs to the electrochemical corrosion. Soil corrosion of the main factors affecting soil resistivity, the oxidation potential of the soil, salinity, water and air content, soil temperature, acidity, microbial, stray current. For this anti-corrosion type, I developed special dedicated gas pipeline anti-corrosion tape, it has the following characteristics: 
 1, the layer thickness uniformity and adhesive sealing performance. 
 2, the substrate and adhesive binding, unglued phenomenon does not exist in the storage or construction process. 
 3, heat aging resistance and UV resistance. 
 4, high tensile strength, elongation at break is appropriate, to facilitate mechanization and manual winding. 
 Varieties, specifications, full color, including anti-corrosion zone (zone) protection zone (takeaway), fill the mouth with anti-corrosion primer and construction equipment. 

 b, polyethylene drainage pipes, anticorrosive adhesive tape 
 1, this product has excellent water resistance and oxidation resistance. 
 2, adhesive tape contained in the adhesive layer of butyl rubber has excellent resistance to oxidation. 
 3, the preservative system of this product with inner anti-corrosion anti-corrosion system with the outside protective layer resistant to mechanical impacts posed by stratified, not only the anti-corrosion effect.
