Development Trending of PPR Pipe
PPR pipe is a commonly used pipe. PPR is made of random copolymer polypropylene as the base material after modification treatment. Compared with other polypropylene, it has better mechanical properties, higher tensile yield strength and impact resistance. It is an excellent material for hot water delivery pipes. The ppr water pipe is non-toxic and hygienic, easy to install, and has good chemical resistance. In particular, it has good thermal welding performance. The molecules and molecules at the connection are completely integrated, which solves the problem of water leakage at the pipe connection that has plagued the water supply industry for a long time. Can be widely used.
In recent years, the average annual increase in the use of ppr water pipes in Europe is more than 15%. At present, more than 80% of indoor water pipes use ppr water pipes. According to the development trend of the domestic PPR pipe industry, according to the "Tenth Five-Year Plan of the National Chemical Building Materials Industry and the Outline of the 2012 Development Plan", by 2005, the share of plastic pipes in various pipe markets will reach more than 50%, of which construction Plastic pipes are used for 60% of hot and cold water supply and heating pipes. By 2012, this proportion had increased to 80%. According to estimates, from 2005 to 2015, my country's average annual demand for indoor cold water pipes was about 500 million meters, and the demand for hot water pipes was about 200 million meters. In addition, in addition to the renewal of hot and cold water pipes in hotels and the construction of industrial pipes, the annual demand for pipes is about 1.5 billion meters. my country's construction department has taken ppr pipes as the first product among the three new plastic pipes to be promoted. It is foreseeable that the PPR tube will develop rapidly in our country, and its market potential is huge. But behind the prosperity of the PPR school, there are problems that cannot be ignored.
