PPR Pipe

PPR Pipe

PPR pipes have the advantages of energy saving, environmental protection.

PPR pipes have the advantages of energy saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, no scaling, simple construction and maintenance, long service life, etc., and are widely used in building, water supply and drainage, urban and rural water supply and drainage, power and cable sheath, industrial fluid transportation, agricultural irrigation and other construction industries and markets.

1.Why is the color of PPR water pipe different?


PPR particles supplied by manufacturers have different colors, such as gray, etc., but most companies buy transparent raw materials, and different colors are added with different color masterbatch.


2.Is there an inevitable relationship between color and quality of PPR water pipe?


No, However, there are more cases that the white PPR fails to pass the light avoidance test, while the gray and green ones do not have these problems. In addition, influenced by living habits, white PPR pipes are mostly used in the north, while gray PPR pipes are more used in the south.


3.How to distinguish PPR water pipe from hot water pipe?


PPR pipe is divided into cold water pipe and hot water pipe. 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 are marked with such signs as S5 S4 s3.2 s2.5. Generally, S5 S4 is a cold water pipe with thin wall thickness, and s3.2 s2.5 is a hot water pipe with thick wall thickness.


4.What are the characteristics of PRR water pipe connection technology?


The interface of PPR pipe adopts hot-melt technology, and the pipe orifice and the pipe orifice are completely integrated together, so once the installation and pressure test pass, there will be no water leakage, and the reliability is very high.

 

PPR is a kind of random copolymerized polypropylene (PP and PE) synthesized by gas-phase method. Its structural feature is that the PE molecules are irregularly linked in the PP molecules, with molecular weight ranging from 300
