PP-R Pipe.also called random copolymerized polypropylene (type Ⅲ)pipe,is a new generation of environment-friendly construction material developed in the 1990s.Besides plastic pipes' merits such as lightness.corrosion resistance.anti-deposition and long service life.PP-R pipe also enjoy some other advantages,like hygienicness,heatresistance and longer service life.Meanwhile,its coefficient of heat conductivity is quite low and it is good at heat preservation and energy conservation.Because of the technique of thermosol binding,it is convenient to be installed and reliable in joints.Also,the material can be recycled.Therefore,it is worthy of the name environment-friendly construction material. Compared with aluminum multiunit pipe,PP-R pipe can be made into tubular products with larger calibers,with the largest reaching more than 163mms in caliber. PP-R pipes and pipe fittings are widely used in such areas as delivery of drinking water,production and delivery system of purified water and drinks,transportation of chemical fluids,heating pipes,circulation system of hot water,pipes in agriculture,planting in gardens,parks and ranches,etc.
