1. Hygiene: It is a green building material without chemical action. PP-R raw material is polyolefin, and its molecule is only composed of carbon and hydrogen elements, with reliable health performance.
2. Convenient and reliable installation: notice hot melt connection is adopted, and a joint connection can be completed in a short time, which is convenient and time-saving.
3. Thermal insulation and energy conservation: the thermal conductivity coefficient is 0.24W/m · k, which is only one hundredth of that of metal pipes, and the heat loss for hot water pipes is very small.
4. Light weight, high specific strength: the specific gravity is about one of the eight of the steel pipe. The pressure test has high strength, good toughness and good impact resistance.
Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving, material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, simple construction and maintenance, and long service life. They are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, power and cable sheaths, industrial fluid transmission, agricultural irrigation and other construction, municipal, industrial and agricultural fields.
