Teach you how to identify the true and false water pipes

How to identify the true and false water pipes?

You can refer to the following points to identify methods:
(1) Product Name: The product name of PP-R shall be "PP pipe for hot and cold water or "PP-R pipe for hot and cold water" and "PP-R" or ultra-fine particle modified polypropylene pipe (PP-R). PP-R cold water pipes, PP-R hot water pipes, PP-E pipes, etc. All of the informal names are pseudo PP-R pipes.
(2) The product testing unit is a non-professional unit. The content of the test item does not conform to the content listed in the standard of the PP-R pipe. The product recommendation department or the product promotion department does not understand the PP-R product standard or the department without the PP-R standard. All issued certificates are pseudo-PP-R.
(3) The density of pseudo PP-R is slightly larger than that of PP-R.
(4) The PP-R tube is matte white or other colors, and the pseudo PP-R tube is bright or colorful.
(5) The PP-R tube is completely opaque, and the pseudo PP-R tube is slightly translucent or semi-transparent.
(6) The PP-R tube feels soft, and the fake PP-R tube feels smooth.
(7) The landing sound of PP-R pipe is dull, and the sound of the pseudo PP-R pipe is crisp.

The real PP-R pipe shall comply with the standard ISO/DIS 15874.2-1999 <<Plastic piping system for hot and cold water -PP part 2 pipe>> Pipe fittings shall comply with the standard ISO/DIS 15874.2-1999 <<Cold and hot water plastics Pipeline system--PP part III pipe fittings;; The performance of pseudo PP-R pipe and pipe fittings cannot pass the above standards. It should be pointed out that the use of pseudo-PP-R pipe is only 1-5 years, while the real life of PP-R pipe is more than 50 years.

1X37 Stainless Steel Wire Rope

There are two types of wire rope corrosion: external corrosion and internal corrosion.
Inspection of external corrosion: Visually inspect the wire rope for rust, pitting, and loose wire.
Internal corrosion is not easy to detect. Corrosion of wire rope is the killer of 1*37 Stainless Steel Wire Rope, so it is very important to prevent the occurrence of wire rope corrosion. If it is a wire rope with a smaller diameter (≤20mm), the wire rope can be bent by hand for inspection; if the diameter is larger, the wire rope can be inserted into the fiber for internal inspection. After the inspection, the wire rope should be restored to its original state, taking care not to damage the rope core , and add lubricating grease.

The materials of 1*37 steel wire rope are 201, 304, 316, 310, galvanized and so on. Specifications are generally 0.3-8mm
