Mine-use plastic-coated steel pipe: It is a steel-plastic composite pipe with antistatic and flame retardant properties made by coating a special polyethylene material on the inner and outer surface of the steel pipe by applying a special polyethylene material to the welded steel pipe or seamless steel pipe as the base pipe.
    Plastic-coated steel pipe is a product that is coated internally and externally with PE (modified polyethylene) hot-dip plastic or EP (epoxy resin), and has excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and does not produce electrical corrosion. Low water absorption, high mechanical strength, low friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent the destruction of plant roots and soil environmental stress. Easy to connect and easy to maintain.
     Mine plastic-coated composite pipe is a general pipe in coal mines, which can be used for water supply and drainage, positive pressure ventilation, negative pressure ventilation, spraying and gas pumping in underground coal mines, and shall not be used for other purposes, and the use pressure shall not exceed the nominal pressure.
