How to distinguish between genuine and fake PPR?

Product name: The product name for PP-R should be “Polypropylene pipes for cold and hot water” or “PP-R pipes for cold and hot water”. Any names that include terms such as ultra-fine particle modified polypropylene pipes (PP-R), PP-R cold water pipes, PP-R hot water pipes, PP-E pipes, etc., are considered non-standard names and represent fake PP-R pipes. The product testing units are not professional, and the test items carried out do not conform to those specified in the standards for PP-R pipes. Certificates issued by departments responsible for recommending products or promoting them, or by departments that have no knowledge of the PP-R product standards or no such standards at all, are all considered fake PP-R certificates. The density of pseudo-PP-R is slightly higher than that of PP-R. PP-R pipes are available in a white matte finish or other matte colors, while fake PP-R pipes have a shiny finish or bright colors. PP-R pipes are completely opaque, while pseudo-PP-R pipes are slightly transparent or semi-transparent. PP-R pipes have a soft feel, while fake PP-R pipes have a smooth feel. PP-R pipes produce a dull sound when dropped, while fake PP-R pipes produce a clearer sound.

Teach you how to distinguish between genuine and fake aluminum-plastic pipes. Currently, in order to seek profits, some international companies and manufacturers are introducing many fake and inferior products on the market; it’s easy to fall victim to deception if one isn’t careful. So how can one identify genuine aluminum-plastic pipes from fake ones? 　　1. Look, identification is carried out by inspecting and feeling the nominal markings on the pipe material as well as its inner surface layer. 　　2. In case of a fire, use an open flame to extinguish the pipe. 　　Genuine aluminum-plastic pipes are welded using either low-frequency butt welding or hydrogen arc welding, resulting in very tight joints; moreover, after the open flame is extinguished, the aluminum layers do not separate. 　　Fake and inferior aluminum-plastic pipes, as well as other types of composite pipes, lack rivets in their aluminum sheets, resulting in loose connections; after being extinguished, aluminum shards will fall off. 　　3. Cutting: Use pipe cutters to cut the pipe into strips in a drill-like manner, and manually separate the aluminum layer from the PE layer. 　　True aluminum-plastic pipes have a 5-layer composite structure, with the aluminum layer adhering tightly to the PE layer; it is not easy to separate the aluminum layer from the PE layer by hand. 　　As for substandard goods, due to shoddy manufacturing, the aluminum layer and the PE layer are not sealed properly, making it very easy for them to separate and fall apart. 　　4. Testing: Use a medium-pressure pump to test the pressure resistance of the piping. 　　True aluminum-plastic pipes have a high internal pressure during shooting, and in most cases they meet or even exceed the requirements set by national standards ； 　　As for substandard goods, their internal firing pressure is normally low to fairly low, making it difficult to meet the requirements for satisfactory use.

Thank you for the answer, but it seems a bit difficult to grasp.

It’s mainly about finding professional construction teams; they use them frequently, so it’s easy to tell them apart.

PPR pipes – you can get them from renovation teams, or there are many options in the labor market as well.
