Good Sealing Steel Plastic Composite Pipe For Underground Coal Mine No Leakage
Mine pipe refers to a product specially developed for special underground environmental conditions, which has the advantages of flame retardant, antistatic, corrosion resistance, long service life and strong safety. It is mainly used in five systems: mine drainage pipe (KS), mine grouting pipe (KJ), mine positive pressure air pipe (KFZ), mine negative pressure air pipe (KFF), mine gas drainage pipe (KW).

High pressure, good mechanical properties: the base pipe is reinforced welded steel pipe or high pressure seamless steel pipe, the inner and outer surface of polyethylene or epoxy resin anticorrosive treatment, the perfect combination of steel pipe and plastic pipe. Continued the advantages of steel pipe, its mechanical strength is very high, impact, bending, pressure and strength and other external forces have a strong bearing capacity.
Chemical corrosion resistance, weathering resistance and aging resistance are very high: the coating can prevent metal oxidation, and has the corrosion resistance of acid, alkali and salt. The product has excellent anti-aging performance, and its service life is much higher than other pipes. The product can be painted with flange to ensure the anticorrosion effect of the whole pipeline.
Coating adhesion is strong: physical method is used for advanced treatment of the base pipe. The pretreatment meets Sa2.5 standard. Microcomputer is used for automatic preheating control and production. Coating adhesion is higher than national standard.
