In the process of using PPR tubes with different brands and different prices in the market, how do consumers conduct product quality inspections.

One: color recognition

The ppr tube itself has no color. During processing, ppr color masterbatch will be added to the pure color ppr tube. After these color masterbatch are added, the pipeline will have a variety of different colors. The color and luster of the high-quality ppr tube are Consistent, no obvious chromatic aberration appears. If you observe carefully, there is no variegated color on the surface.

Two: texture recognition

In the selection of raw materials, high-quality ppr pipes are not added with various impurities. Its texture will be relatively pure, the surface is smooth, and the hand feel is soft. Some rougher pipes indicate that it is added to the selection of raw materials. A lot of different impurities, which will cause its particles to be more complicated.

Three: Hardness determination

The ppr tube itself has a certain degree of toughness. According to the thickness of the pipe, its hardness will be different. If a ppr tube is easily deformed, the quality of the ppr tube is inferior, and the thickness is generally 4 A millimeter pipe requires a lot of force to bend it.

Four: wall thickness detection

There are certain requirements for the pipe wall thickness of ppr pipes, which can be measured with a dipstick. The difference in the size of the pipe shall not be outside of 0.5 mm, and the inner diameter and diameter of the pipe have strict requirements.

Five: Material testing

The more direct way to detect the material of the ppr tube is to intercept a part of it and connect it in the hot melt machine to see if it has some peculiar smell at high temperature. If the smell is heavier, the material selection of the ppr tube will be poor, and vice versa. better.
