At present, there are hundreds of PPR water pipes on the market. What kind of PPR water pipe is a good water pipe? In fact, the most important thing for a good water pipe lies in the solid materials, which can be roughly divided into the following points:
Mechanical Properties
Good mechanical properties are essential elements for high-quality PPR pipes. Since it is used in the water supply system, the PPR pipe needs to withstand a certain water pressure for a long time, so the most important mechanical property of the PPR pipe is the pressure resistance. There are many factors affecting the mechanical properties of pipes, which are related to equipment and technology, the uniformity of mixing materials, and the performance parameters of raw materials.
Corrosion And Scaling Resistance
Corrosion resistance and anti-scaling are the basic needs of daily water for pipelines. Good PPR pipes have better chemical corrosion resistance and can resist the erosion of chemical elements in the water. At the same time, the smooth inner surface can avoid the formation of scale, making the transported water more clean and hygienic.
High Temperature And High Pressure Resistance
The melting point temperature of relatively pure PPR raw materials is 220 ° C. If other impurities are added to the raw materials during manufacture, the melting point of the mixture will drop, resulting in a drop in the softening point. This means that the water pipes tend to become soft at lower temperatures and their compressive capacity is reduced.
Easy To Solder
PPR pipes made of high-quality PPR raw materials are easier to weld, and the welding openings expand evenly during welding, making the welding firmer. Since the melting point of the PPR water pipe doped with impurities decreases, the melted part is easy to become thin and soft during welding, and it is not easy to socket and insert during welding, which affects the welding quality and also causes the diameter of the water pipe to become smaller. .
Solid Material
The wire ports used in good PPR metal pipe fittings are made of high-quality brass materials, and the amount of brass will not cut corners to ensure the safe and reliable operation of the piping system.
