As we all know, the aluminum alloy lined PPR pipe is also called the three-type polypropylene pipe. It is a pipe made of random copolymer polypropylene through extrusion molding. The injection molded pipe has good impact resistance and long-term creep performance. So what are the selection techniques for aluminum alloy lined ppr tubes?
Selection skills of aluminum alloy lined ppr pipe:
It is suitable for industrial and civil buildings in daily life, used for clean drinking water and hot water heating. There are two types of aluminum-plastic ppr pipes: cold and hot water pipes. The wall of the cold water pipe is thinner, and the wall of the hot water pipe is thicker, so the hot water pipe is much better in terms of anti-cracking, and the price of the hot water pipe is a little higher than that of the cold water pipe. For the sake of safety, many manufacturers have increased the safety factor regardless of whether the hot and cold water pipes are broken during the construction period.

Soft polypropylene R hose, the pipe fittings are not easy to be squeezed and deformed, even if deformed, it will not break, and greatly reduce the amount of joints; corrosion-resistant and waterproof polypropylene R hose, the chemical properties of the pipe fittings can resist the corrosion of chemical elements in the water , The smooth inner surface can prevent the formation of water temperature; high temperature resistant, high pressure resistant polypropylene R hose, water pressure resistance at room temperature is 45 kg/cm², and the temperature of the non-deformation tube is 112°C; long-life polypropylene R hose, Anti-aging, the normal service life is more than 50 years; the construction of PPR pipes is simple and easy, and the flexibility of the pipe fittings makes the construction speed fast, and the connection is convenient, safe and reliable; economical because of the simple construction, it will not have opposition and influence with other projects, and shorten the construction period , The construction cost is 60% less than the copper pipe, and the economy is good.
Therefore, consumers must be cautious when buying, and must choose the right tube produced by a large manufacturer with quality assurance. In addition, pay more attention to the equipment and listen to the opinions of experts.
The production process of polyvinyl alcohol resin pipe is also very important. According to the horizontal, horizontal and vertical principle, a trench larger than the diameter of the water pipe should be made on the ground at the root of the room, and then the PPR water pipe should be laid, and then thermally welded in turn. After all PPR interfaces are fused with hot melt technology, they must be subjected to a compression test for more than 24 hours. If the site environment permits, the compression test time can be longer. After confirming that there is no leakage, landfill is carried out.
It can be seen that the three-type polypropylene tube has the advantage of myocardial infarction, has good impact resistance, and has been widely used in industry and construction. Its connection method is also a hot melt machine socket connection, which is very popular Everyone must master these purchasing skills when choosing a kind of pipe.
