PRESSURE NOMINAL - PN
PPRC polypropylene random Copolymer stands for, can provide very high performance even under high and low temperatures and pressure conditions. Heating and hot water systems used in fresh water polypropylene random copolymer (pprc) pipes ultra-high molecular structure due to a high level of use and durability. Briefly, PPR is a type of polypropylene plastic pipe that has some advantages over other plastic pipe used in residential and commercial plumbing (e.g. PVC and CVPC). The main advantages are stability, durability (up to 50 years) and leak resistance. Downsides are cost and need for specialized tools for making joints (the pipe is joined using a heat fusion welding rather than glues as for PVC pipes).
