As the name suggests, the water pipe is the water supply pipe, and now the general water pipe in the home decoration adopts a buried wall construction. The water pipes are divided into three categories according to their different materials. The first category is metal pipes, such as the common copper pipes and stainless steel pipes. The second category is steel-plastic composite pipe, aluminum-plastic composite pipe, etc., and the third category is plastic pipe. The galvanized pipe is used as a water pipe after several years of use. A large amount of rust will be produced in its tube, so that yellow water will flow out, and then it will not only pollute the sanitary ware, but also contain some bacteria produced by the unsmooth inner wall, and the metal content in it is too high, which seriously endangers the health of the human body. The state prohibits it from being used as drinking water pipes. The copper pipe is a high-quality product in the water pipe. It is relatively corrosion-resistant and easy to sterilize. His copper pipe interface methods include ferrule, welding and self-locking card room connection, but after a long time of his ferrule, he will easily leak water, and welding is to use a hot melt process to fuse the two together. To achieve the effect of connection, but their welding gas is difficult to meet the standard, it is easy to cause the weld to rust, which directly reduces the first service life of Guangzhou, and then the installation quality is very high for the technical requirements of his own welding workers. Then the quality is relatively difficult to stabilize. However, their installation risk is relatively low, suitable for various installation environments, it can be reused, and its environmental protection performance is relatively durable and reliable. But its price is relatively expensive, and then the construction of welding will be higher. They rarely have home decoration and use welded copper pipes.
