The introduction of PP-R piping
1. PP-R pipe, also called polypropylene random copolymer pipe(3 style), is a new generation of green building material developed and produced in the 1990s.
2. As light as other common plastic pipes, it is corrosion-resistant and antiscaling, and has a long life span with its excellent hygienic properties and good thermal endurance quality.
3. It is genuine green building material in reality as well as name for its low coefficient of heat conductivity, heat preservation, energy conservation, easy installation, dependable hot melted connection and recyclable materials.
4. Unlike copper-plastic composite pipe, PP-R pipe can have heavy caliber pipes produced, with a maximum caliber of over 160mm.
