At present, 70 to 80% of PPR pipes on the market are not real PPR pipes. In order to help users to initially identify the authentic PPR tube and fittings from the appearance and feel. You can refer to the following points to identify methods: (1) Product Name: The product name of PP to R shall be “PP pipe for hot and cold water or “PP-R pipe for hot and cold water†where ultra-fine particle modified polypropylene pipe (PP-R) or PP ~ R cold water pipe, PP ~ R hot water pipe, PP ~ E pipe, etc., the informal name are pseudo PP ~ R pipe. (2) The product testing unit is a non-professional unit. The content of the test item is inconsistent with the contents listed in the standard for the PP to R pipe. The product recommendation department or the product promotion department does not understand the PP to R product standard or does not have a PP to R standard. The certificates issued are pseudo PP-R. (3) The density of pseudo PP to R is slightly larger than that of PP to R. (4) PP-R tube is matt white or other color matte, pseudo PP ~ R tube shiny bright or bright colors. (5) The PP-R tube is completely opaque, and the pseudo PP-R tube is slightly light-transmitting or semi-transparent. (6) PP to R tube feel soft, false PP ~ R tube feel smooth. (7) The floor sound of PP-R pipes is more boring, and the sound of pseudo PP-R pipes is crisper. The real PP-R pipe should comply with the standard ISO/DIS 15874.2-1999 <<Plastic pipe system for hot and cold water to ~PP second part pipe>> The pipe fittings should meet the standard ISO/DIS15874.2 to 1999 <<Hot and hot water use Plastic pipe system ~ ~ PP third part pipe fittings;; pseudo PP ~ R pipe and fittings performance is not able to pass the above criteria. It should be pointed out that the service life of pseudo PP-R pipes is only 1 to 5 years, while the service life of real PP-R pipes is 50 years. PPR pipes generally require standard series and pressure ratings. S5 = 1.25 MPa S4 = 1.6 MPa S3.2 = 2.0 MPa S2.5 = 2.5 MPa S2 = 3.2 MPa Heating generally uses S3.2 or more. Look at the color, really white opaque, slightly transparent As a workman, the tube cuts at the two ends of the Kinder tube are very neat, with no burrs, and the wall thickness is uniform; the false tube is opposite See the word mark. True tube word mark can be erased; Fake tube word mark is difficult to erase: 1 The authenticity is shorter, the harder, the longer the softer; 2 The thickness of the wall can not be identified as authentic; 3 From the cross-section, genuine and shiny , counterfeit goods are dark; 4 authentic trademark printing on the wall is clear, counterfeit goods are fuzzy; 5 has not confirmed that the JD pipe has a security logo, plus 20 on the pipe security code, you can find the answer. (The pipe produced after October 24, 2002 has this mark). Second, JD pipe production equipment for the world's most advanced production equipment, production speeds up to 14 to 18 meters per minute, while the fastest domestic other equipment is 6 to 8 meters, so according to the number of printed logo on the pipe to calculate the number of production The number of meters can tell whether it is our pipe. Third, JD's pipe cold water pipe appearance is matt, not shiny, the end of the pipe is very rounded, no scratches, no traces of the eye and other traces; hot water pipe is high light, shiny, very rounded end, no scratches, No traces of needles and other traces. This has to rely on the usual observation, and more can be seen with other manufacturers of pipe.
