Product Overview

PPR is a random copolymer polypropylene synthesized by (PP and PE) gas phase method, and its structural characteristics are that PE molecules are irregularly linked to PP molecules, and the molecular weight ranges from 300,000~800,000. The pipes produced by PPR raw materials, also known as random copolymer polypropylene pipes, are plastic pipe products developed and applied in the late 80s and early 90s of the 20th century. With its excellent performance and wide range of applications, it has occupied a place in the plastic pipe market and is recognized as a green and environmentally friendly product. However, in recent years, the market operation, the above-mentioned PPR plastic pipe quality problem analysis example found that there are many problems in the PPR pipe market, which restricts the benign development of PPR pipe to a large extent.

Product Features

PPR water pipe is divided into cold water pipe and hot water pipe, how to distinguish it?

PPR pipes are divided into cold water pipes and hot water pipes, the difference is that there is a blue identification line on the cold water pipe, and a red line on the hot water pipe. In addition, PPR pipes. There are logos such as S5, S4, S3.2, S2.5 and so on, generally S5 and S4 are cold water pipes with thin wall thickness, and S3.2 and S2.5 are hot water pipes with thick wall thickness.

What are the characteristics of the connection technology of PRR water pipes?

The interface of the PPR pipe adopts hot melt technology, and the nozzle and the nozzle are completely integrated together, so once the installation pressure test is passed, there will be no water leakage again, and the reliability is extremely high.
