the end of each printed mark on the pipe is 20 Arabic numerals, that is, the anti-counterfeiting code. Dial the anti-counterfeiting phone: 024-86541001 to distinguish the authenticity. At present, 70 ~ 80% of PP ~ r pipes in the market are not real PP ~ r pipes. In order to help users preliminarily identify the true and false PP ~ r pipes and fittings from the appearance and feel

the following identification methods can be referred to:

(1) product name: the product name of PP ~ r should be "polypropylene pipe for cold and hot water or" PP ~ r pipe for cold and hot water ". Where it is prefixed with 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 is false PP ~ r pipe

(2) the product testing unit is a non professional unit, and the content of the test items is inconsistent with the content listed in the PP ~ r pipe standard. The certificates issued by the product recommendation department or the product promotion department, the Department that does not understand the PP ~ r product standard or the Department that does not have the PP ~ r standard are all fake PP ~ R

(3) the density of pseudo PP ~ r is slightly higher than that of PP ~ R

(4) PP ~ r tubes are white matte or matte of other colors, and pseudo PP ~ r tubes are bright or colorful

(5) PP ~ r tube is completely opaque, and pseudo PP ~ r tube is slightly translucent or semi translucent

(6) PP ~ r tube feels soft, while pseudo PP ~ r tube feels smooth

(7) the landing sound of PP ~ r tube is dull, and the landing sound of pseudo PP ~ r tube is crisp

the real PP ~ r pipe should conform to the standard iso/dis 15874.2 ~ 1999 <& lt; Plastic piping system for hot and cold water ~ ~ PP Part II pipes >& gt; Pipe fittings shall comply with the standard iso/dis15874.2 ~ 1999 <& lt; Plastic piping system for hot and cold water ~ ~ PP Part III pipe fittings >& gt;; The performance of pseudo PP ~ r pipes and fittings cannot pass the above standards. It should be pointed out that the service life of pseudo PP ~ r pipes is only 1 ~ 5 years, while the service life of real Jinde PP ~ r pipes is more than 50 years
