Internal and external coating steel pipe due to the inner wall of epoxy resin, so the surface smooth, reduce fluid resistance, reduce flow resistance, increase the flow, and not scaling, not easy to breed microorganisms. To solve the ordinary fire water supply pipe and galvanized steel pipe buried and water corrosion and scaling problems, will not occur clogging the pipeline and plug the phenomenon of the spray, the protective layer does not fall off, uplift, softening, blistering, cracking, peeling. Reduce the phenomenon of adhesion to improve the life of the fire water supply pipeline, while the fire inside and outside the coating steel pipe has excellent resistance to chemical corrosion, water resistance and resistance to resistance, protein, high degree of foam fire extinguishing agent corrosion, Water, buried and acid, alkali salt corrosion of metal pipes; due to the use of heavy-duty modified epoxy resin is thermosetting plastic, and added a flame retardant, coating temperature is good. Can be used in 30 degrees -90 degrees long-term, and does not burn, do not soften, high strength; fire inside and outside the life of coated steel pipe for 50 years, is now used for more than 10 years, although the one-time investment in galvanized steel pipe Slightly higher, but the fire inside and outside the use of coated steel pipe to reduce the maintenance costs, eliminating the need to replace the pipe costs, from the operation, management and service life is far more economical in galvanized steel pipe. Epoxy coated steel pipe is a regular steel pipe after surface treatment, in the steel pipe coated with a layer of characteristics of the epoxy resin material and made. The coated steel pipe used in the epoxy resin powder has excellent resistance to chemical corrosion, long-term use will not appear rust corrosion, wall fouling and many other issues, to avoid the occurrence of internal congestion affect the pipeline patency. As the coating material for high temperature modification, making the product's temperature performance compared with other similar products has been greatly improved in the surrounding environment, the sharp rise in temperature will not affect the use, thus greatly improving the automatic sprinkler system Life and reliability
