1, the production of energy saving insulation PP-Rppr only 20% of steel, and its low thermal conductivity [0.2W / (mK)], is only 1/200 of steel pipe, used in hot water systems will greatly reduce heat loss.
The inner wall 2, foam polyurethane insulation pipe corrosion, scaling, health, non-toxic to use PP-R pipe can be removed from the use of galvanized steel pipe caused by fouling, rusty water quality caused by the "secondary pollution." Since PP-R component simple, basic ingredients for carbon and hydrogen, in line with food hygiene regulations, non-toxic, more suitable for transporting drinking water.
3, buried ppr pipe insulation heat, pressure, temperature and long service life of long-term use PP-R pipe up 95 ℃, short-term use temperature up to 120 ℃. The temperature is 70 ℃, working pressure of 1.2MPa conditions, the long-term continuous use, life expectancy up to 50 years.
4, lightweight, high strength, fluid resistance PP-R pipe density of only 1/8 of metal pipes, pressure-resistant test strength up 5MPa, and good toughness, impact resistance. Since the wall is smooth, no rust, no scaling, fluid resistance.
