The prospect of aluminum plastic pipeThe prospect of aluminum plastic pipe
The competition among various indoor water supply pipes has intensified. There is a saying in the building materials market that "PP-R plastic pipes are a substitute for aluminum-plastic pipes."
On October 28, 2002, at the second annual meeting of the "Water Supply Committee of China Construction Water Supply and Drainage Committee", Huang Ruhong, chairman of the Pipeline Committee of the Water Supply and Drainage Equipment Branch, wrote an article that "Pipe fittings and connections are an easy to overlook but very critical selection of pipes. The article pointed out that “it is unwise for many developers to pay insufficient attention to pipe fittings and connections. In the history of pipe material development, there are many precedents that determine the fate of pipe materials due to pipe fittings. For example, in Japan in the 1970s, the current PP- The soldering iron used in the R tube is used for socket hot-melt connection. It is claimed that after careful and strict testing and optimization of various connection methods, it is concluded that this connection method is the most reliable. This connection is also regarded as a national standard (JIS standard) Promotion. However, after more than 10 years of practice, I have objections to the original method. It is found that this connection method is difficult to grasp the degree of heating and melting, and the connection is loose and cracked. Therefore, it is believed that a metal compression rubber ring machine should be developed. Connectors." Examination "The Yokohama Water Works Bureau of Japan has abandoned its use since the late 1980s."
Among the new types of plastic pipes, the performance is better and the worse is determined here: aluminum-plastic composite pipes have been "selected" as the preferred cold and hot water supply pipes and ideal heating pipes with unparalleled advantages. Compared with other pipe materials, the development of aluminum-plastic composite pipe in China is quite mature, with complete product standards and application specifications, and is widely accepted by the market. The rapid development trend of foreign aluminum-plastic composite pipes also confirms this fact: according to the statistical results of the German KWD Plastic Information Center, in Europe, aluminum-plastic composite pipes are increasing at an annual rate of more than 20%, and the amount far exceeds other plastics such as PPR and PB. Pipe. It is believed that in China, "Queen" water pipes-aluminum-plastic composite pipes will have a broader market space!
