in 2003, the total output of plastic pipes in china broke through 1 million 800 thousand t, up 23% from the same period. in the early days, pp pipes were mainly used as agricultural water conveyance pipes. however, due to the early performance of products, there were still some problems (such as poor impact strength&poor aging resistance),&the market could not be opened. with the shanghai plastic building materials factory the first introduction of foreign advanced technology, the transportation of imported pp-r material production of cold&hot water in the pipe has been recognized by the market, many manufacturers he the construction of pp-r pipe production line, the price from the initial production of 20 thousand ~3 million /t continue to decline, but the share of pp-r pipe material in the plastic pipe market. is still low. it is reflected that there is a gap between the domestic pp-r materials&the imported materials,&the quality needs to be improved&improved. according to reports, south korea has developed a new brand of pp-r 112, a high pressure resistant water supply pipe. the pipe produced by this brand can be used for 50 years under the condition of ultra-high pressure of 20&11.2mpa.
