Product performance and use:
CPM series mat (pipe coated mat series)
C-PM series mat is a kind of glass fiber substrate for anticorrosion of buried steel pipeline for transporting oil and natural gas. It has high strength, good flexibility, uniform thickness, good solvent resistance and water vapor corrosion resistance, non-decay, flame retardant and other characteristics, and has good impregnation compatibility with coal tar enamel and asphalt. The oil and natural gas transportation pipeline coated with asphalt coal tar enamel and CPM mat has excellent impermeability and resistance to various environmental media, which can prolong the service life of the pipeline to 5060 years and significantly reduce the cost of maintenance and replacement. After test, the technical specifications of CPM series glass fiber mat meet and even exceed the technical requirements specified in the natural gas industry standard SYT0079 of the People's Republic of China and the AWWA C / 203 standard of the American Waterproof Engineering Association, so it is an ideal internal and external winding tape substrate for covers such as asphalt and coal tar enamel.
