1. Logo: Check the content of the logo of the pipe, generally including the name (trademark) of the manufacturer of the ppr pipe, product name, type, size, production date, batch number, quality certification, etc.;
2. Wall thickness: to see whether it is strictly in accordance with the national standard GB/T18742.2-2002, using caliper measurement standards;
3. Color: A good ppr tube village looks milky (not all white), the surface is smooth (not smooth), the feel is soft, and there are no impurities;
4. Light transmittance: good ppr pipes are completely opaque, and pseudo PPR pipes are slightly light or semi-transparent;
5. Sound: The sound of high-quality pipes is dull, and the sound of inferior pipes is crisp.
Correctly distinguish the difference between ppr pipes. Through this article, I believe everyone has a basic understanding. The real ppr pipes should comply with the standard ISO/DIS 15874.2-1999 "Plastic piping systems for hot and cold water-PP Part 2 pipes". The performance of the inferior ppr pipe cannot pass the above standards. It is worth noting that the service life of inferior pipes is only 1-5 years, while the service life of high-quality ppr pipes and fittings is more than 50 years.
