There are many plumbing materials. Different materials have their own advantages and disadvantages. Therefore, you must purchase them when you choose. Then, what are the types of plumbing materials? What are the characteristics of each material hose? What kind of material is better? PART1. Household hose material classification Household water pipes are household water supply pipes. The commonly used methods are buried wall concealment methods. Now, household water pipes are generally divided into three categories: The first type is a plastic complex metal pipe, such as a plastic compound steel pipe, an aluminum plastic composite pipe. Wait. The second category is plastic pipes, such as PB, PP-R and so on. The third category is metal pipes, such as hot-dip cast iron pipes, copper pipes, stainless steel pipes and so on. PART2. What kind of home water pipe material is good? Today's general household water pipes use: PPR hot-melt pipe, aluminum-plastic composite pipe, steel-plastic composite pipe, galvanized steel pipe has rarely been used again. PPR water pipes: If hot water and cold water are mixed, use hot water pipes. After the PPR pipe hot water pipe is thickened, it can guarantee a kind of stability, and it is not easy to appear damage in the future hot and cold exchange. The biggest advantage of the PPR pipe is that its pipes and fittings are hot-melted, and the pipes and fittings are integrated after hot-melting. This pipe is buried directly in the ground or in the wall, and the risk in the later stage is very small. Other tubes, like aluminum tubes, are of good quality. Aluminum plastic pipe: If the aluminum plastic pipe is really qualified, the quality should be considered good, but the problems involved in the material, domestic materials, and the corresponding connectors may cause some problems. For example, cracks occur during bending, or leaks occur at joints. This is also a reason why aluminum-plastic pipes are eliminated. Aluminum plastic composite pipe: Aluminum plastic pipe is purely from the pipe itself, it is still relatively reliable, PPR pipe has a unique melting advantage, to ensure the stability of the connection. The new pipe, PPR aluminum-plastic composite pipe, has its own characteristics. In the outer layer of the pipe, there is (PPR) polypropylene material, which can be directly connected with the pipe. In the middle, it is an aluminum layer. In itself, its pressure resistance is much stronger. The inner layer is also a heat-resistant polyethylene material. This material is superior to the PPR tube. Therefore, the combination of the two materials equals the advantages of both the aluminum-plastic tube and the PPR tube. As for which one is better, you can choose the water pipe that best suits your needs. PART3. What is the general size of household water pipes? The general household water pipe specifications are: DN15 (4 in charge), DN20 (6 in charge), DN25 (1 inch), DN32 (1 inch 2 pipe), DN40 (1 inch half pipe), DN50 (2 inch pipe), DN65 ( 2" half pipe), DN80 (3-inch pipe), DN100 (4-inch pipe), DN125 (5-inch pipe), DN150 (6-inch pipe), DN200 (8-inch pipe), and DN250 (10-inch pipe). The pipe Φ25×1/2 means its outer diameter is 25. The actual corresponding nominal diameter is DN20 (that is, people often say 6 in charge). You can buy a 6-point faucet. You can also buy a 4 point faucet (just add a diameter between the tube and the faucet). The styles and materials of household faucets are ever-changing, but the threaded parts that are connected to the pipes are divided into four points, six points, and one inch. Don't worry about buying the wrong one. Generally speaking, the 4-pipe is in inches, so the 4-pipe is 1/2 inch (4/8=1/2), and one inch=25.4mm, so the inner diameter of the 4-pipe is 25.4/2=12.7mm. This is the inner diameter of the so-called DN15 water pipe. 4 points is the length of the English pipe diameter, which is 1/2 inch. It is equal to the metric 15mm. 1 inch is equal to 8 points, and the metric system is 25.4mm. 6 points = 3/4 inches = 20 mm. 4 points = 1/2 inch = 15 mm. Edit reminder: Also keep in mind that the pipes are all calculated with the inner diameter. However, the threaded thread of the pipe is calculated by the medium diameter. It is expressed by the diameter DN. The thread is divided into metric M and inch G. The pipe thread is generally inch, the thread angle is 55 degrees, and the metric is 60 degrees.
