Discrimination mode:

“Look” appearance color, good PP-R water pipe color is soft and uniform, no noise. (PP-R pipes are mainly white, gray, purple, green, yellow, blue and so on. Consumers often think that white is the best. In fact, color is not the standard to judge the quality. Plastic particles are mainly white and transparent colors (there are also other colors that have been added to the color master). As long as the color master is added, any color can be produced. The color master will not be decomposed and will not change the quality of PP-R. In this regard, gray or other opaque properties will be better. But such advantages only exist in the installation of open pipes and pipeline Wells, home water pipes are all buried, so there is no gray is better than other colors. PP-R tubes are completely opaque, and pseudo-PP-R tubes are slightly or semi-transparent. Generally, white products can only be produced with pure PP-R raw materials. For example, the color of products produced with recycled materials, waste materials and corner materials is not soft and uneven, while the color of other color products processed with color master will not be affected by the addition of recycled materials, waste materials and corner materials. This is why many manufacturers focusing on the quality of home improvement retail products are mainly white); The inside and outside surface of the product should be smooth and flat, and no bubbles, obvious depressions, grooves and impurities are allowed.
Touch the texture
Good PP-R water pipe is 100% PP-R raw materials (without any added materials) pure texture, smooth surface, soft feel, pseudo-PP-R pipe feel smooth, generally speaking, coarse particles are likely to be mixed with impurities;
Smell the smell
The main material of PP-R pipe is polypropylene. Good pipe has no smell, and poor pipe has a strange taste. It is likely to be mixed with polyethylene, rather than polypropylene.
Pinch hardness
PP-R tube has considerable hardness, casually can pinch deformation of the tube, certainly not PP-R tube;
Measure the wall thickness
In addition, a vernier caliper can be used to measure whether the pipe wall thickness is up to standard and uniform. Generally, good pipes are produced strictly in accordance with the national standard, but this method requires a certain understanding of the PP-R pipe national standard.
“Listen” to the sound
The landing sound of PP-R tube is dull, while the landing sound of pseudo PP-R tube is clearer.
“Smash” elasticity
Good PP-R tube, “resilience” is good, easy to smash naturally not good PP-R tube, but the temperature below 10 degrees no matter how good PP-R tube can be smashed. But strong hardness is not equal to good elasticity, some manufacturers by adding too much calcium carbonate and other impurities to improve hardness, how can not break, with a long time easy to crack; (Due to the cold brittleness of PP-R raw materials in several temperature range performance is different: 10, -5, -23……)
The smell of burning smoke
PP-R tubes mixed with recycled plastic and other impurities can smoke black and have a pungent smell. And good material after burning not only will not take black smoke, no smell, after burning, the liquid is still very clean. (You can also “pull” to see its “length”)
melt
During PP — R pipeline welding, the normal welding temperature is within the range of 260-290℃, and the welding quality will be better guaranteed during welding. If the product can easily enter the welding die head under the normal welding parameters, and the accumulation tumor of welding is close to liquid, it indicates that the product is not authentic PP — R raw material production. At the same time, if the fused accumulation tumor can be quickly cooled and hardened (generally within 10 seconds), it can also show that the product is not authentic PP — R raw material production, this is because one of the characteristics of PP — R is better insulation effect, its cooling speed will naturally be slow.
Check whether the inner diameter of the pipe is deformed and whether the pipe fittings are drawn. A good PP-R pipe is not allowed to be drawn, and the inner diameter is not easy to be deformed.
“Check”
Use test instruments to detect effectively distinguish between good and bad products. Several very important test requirements are specified in the national standards, such as aging resistance test of pipe (in the ring stress of 1.9MPa, test temperature of 110℃, maintain 8760 hours without failure test), stability test of pipeline system (hot and cold cycles of 5000 times) and impact resistance test, etc. Therefore, users can ask manufacturers or businesses to provide the above test report when choosing, so as to verify. In addition, it is necessary to put forward the national standard for the raw materials used in pipes and fittings also has an important requirement that is the melting index. The national standard requires that the change value of the melting index before and after processing should not exceed 30%, and the industry also has a requirement that the melting index of raw materials should not be greater than 0.5g/10min.
