PP-R pipe is a new type of pipe material, non-toxic, light weight, pressure resistance, corrosion resistance, using a special hot melt connection, will not corrosion rust, no scaling. When selecting, please note: 1 Product name: The product name of true PP-R should be “polypropylene pipe for hot and cold water†or “PP-R pipe for hot and cold waterâ€, where polypropylene is modified with ultra-fine particles Pipe (PP-R) or PP-R cold water pipe, PP-R hot water pipe, PP-E pipe and other informal names are pseudo PP-R pipe; 2 pseudo PP-R density than true PP-R slightly Large; 3 true PP-R tube is matte white or other color matte, pseudo PP-R tube bright and bright or colorful; 4 true PP-R tube is completely opaque, pseudo PP-R tube is slightly light or Translucent; 5 true PP-R tube feel soft, false PP-R tube feel smooth. 6 True PP-R pipe landing sound more dull, fake PP-R pipe landing sound more crisp. The service life of the pseudo-PP-R pipe is only 1-5 years, and the service life of the real PP-R pipe is more than 50 years. There are also copper tubes and stainless steel tubes. Although it is resistant to corrosion and elimination of bacteria, the price is too high. Few people in the general family are interested. Layout to science Nowadays, material management in the building materials market is not standardized. When purchasing electricity and water lines such as wires, switches, lamps, water supply pipes, etc., do not plan to purchase cheaper products. Buy regular factory products, and carefully check the product's production license, business license, and test report. , 3C certification and other information is complete, and to open an official invoice. In the hydropower construction process, the following points are mainly noted: 1. Do not break the original wire or plumbing pipe when drilling. When the electrical pipe is laid, it is necessary to thread the pipe. Do not bury the wire directly on the ground or in the wall. This is not only unsafe, but it cannot be repaired once it is damaged. Plumbing pipes must be pressure tested after they are laid, and they are qualified to do the next process to prevent damage caused by leaking pipes. 2. The parts of the kitchen and the bathroom that need to be waterproof shall be closed after the waterproofing is completed, and then the tiles shall be affixed after being qualified. 3. Wire connectors must be tinned. The kitchen and bathroom fittings are recommended to be waterproof. The connectors can be taped with high pressure self-adhesive tape and black tape. 4. Lamps with a weight exceeding 3 kg must be fixed on bolts or embedded hooks. Use of wooden wedges is prohibited. Metal shells of lamps with installation height less than 2.4 meters must be protected and grounded. Toilets must be waterproof sockets. Aluminum-plastic composite pipe is one of the more popular pipes on the market. It is light, durable, and convenient to construct. Its flexibility is more suitable for home use. Its main disadvantage is that when used as a hot water pipe, due to the long-term thermal expansion and contraction, it may result in the misalignment of the snap-on connection, which may cause leakage. When purchasing the aluminum-plastic composite pipe, two things need to be noted: 1 Check the appearance of the product, and the aluminum-plastic composite pipe of good quality. Generally, the outer wall is smooth. The mark, specification, applicable temperature, and number of meters on the pipe wall are clearly identified. The manufacturer is in the pipe wall. The production number has also been printed, and the inferior products generally have rough outer walls, unclear or incomplete labels, simple packaging, and unknown site or telephone. 2 Look closely at the aluminum layer. A good aluminum-plastic composite pipe has a welded joint at the aluminum layer. The aluminum layer and the plastic layer are closely combined with no stratification, while the inferior products are not.
