Product Detailed
Pp-r pipe with general plastic light weight, corrosion resistance, scaling and long service life

Pp-r pipePp-r pipe and tube type, using polypropylene is become by extrusion of polypropylene copolymerization, injection pipe fittings become.

Pp-r pipe what features?Pp-r pipe in general plastic light weight, corrosion resistance, scaling and long service life etc, also has the following features:1, non-toxic and health. Pp-r materials molecules only carbon, hydrogen, no harmful elements of toxic elements exist, health and reliable, not only for hot and cold water pipe, also can be used for pure water system.2, heat insulating and energy-saving. Pp-r pipe heat conduction coefficient for 0.21 w/mk, only for steel 1/200.3, good resistance to heat. Pp-r pipe vicat softening point 131.5 degrees Celsius. The highest temperature to 95 degrees, which can meet the standard of building drainage water system requirements.4 and long service life. Pp-r pipe in working temperature, pressure (70 ° c P.N) 1. OMPa condition, use life can reach more than 50 years, Under normal temperature (20 ° c) use life can reach 100 years.5, installation is convenient, reliable connect. Pp-r good weldability, pipe, tube can be used to melt and fused connection, convenient installation, reliable connector, its connected intensity than pipe itself.6 and material recycling. Pp-r waste after cleaning, broken by recycling in pipe and tube production. Recycling materials shall not exceed 10% of total amount, does not affect the quality of products.Pp-r pipe main USES what?1, building of hot and cold water systems, including centralized heat-supply system,2 the heating system, building, including floor, wall panels and radiant heating system,Three, can be directly drinkable water supply system,4 and the central air conditioning system (concentration),5, transport or discharge of chemical industry etc in piping systems.How to secure and economic chooses pp-r pipe?1, pay attention to the pipeline using coefficient C (i.e. general safety coefficient) : general situation, and long-term continuous make temperature, optional < 70 degrees C = 1.25, On important occasions, and long-term continuous use of temperature, and 70 degrees may be at higher temperature for a long time, can choose C = 150,2, for more than 40 degrees Celsius (cold) system, the selection P.N 1.0 ~ 160 MPa pipes, fittings, Used for hot water system PN2.0 MPa choose pipe, tube.3 and in consideration of the above three principles, pieces of the SDR shall not be more than the pipe fittings, namely the SDR wall thickness should be not less than the same specification pipe wall thickness.
