1. PPR pipe is light in weight, corrosion resistant, non scaling, long in service life and convenient in installation. PP-R has good welding performance. Pipes and pipe fittings can be connected by hot melting and electric melting. The device is convenient, and the strength of the connection part is greater than the strength of the pipe itself.n2. PPR pipe insulation and energy saving. Its thermal conductivity is 0.21w/mk, which is only 1/200 of that of steel pipe. Vicat softening point of PPR pipe is 131.5 ℃. The maximum working temperature can reach 95 ℃, which can meet the application requirements of hot water system in building water supply and drainage standards.n3. PPR tube is non-toxic and sanitary. The raw material molecules of PP-R are only carbon and hydrogen, and there are no harmful and toxic elements. They are sanitary and can be used not only for cold and hot water pipes, but also for pure drinking water systems.n4. PPR pipe materials can be recycled for application. PP-R waste is recycled and used for pipe and pipe fittings consumption after cleaning and crushing. The amount of recycled materials shall not exceed 10% of the total amount, which will not affect the output and quality.nPPR pipes are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheath, industrial fluid escort, agricultural irrigation and other construction, municipal, industrial and agricultural areas.
