几种常见建筑给水管材的应用（Application of several common building water supply pipes） The application of 2008-09-27 13:39:11| classification of several common pipe engineering technology: | Tags: | name and subscription. Application of several common building water supply pipes At present, our country commonly used plastic pipe: UPVC pipe, PE pipe, PE-X pipe, PP-R pipe, ABS pipe, steel plastic pipe etc.. In Shenzhen, the leading products are PP-R pipe, steel plastic pipe, copper pipe and so on. These pipes can be used for building cold and hot water supply, heating and gas supply according to the use environment. Data show that in 2001~2010 years, in the field of engineering construction, building water supply demand per year (5~6) x 105km. 1. several common pipe properties 1.1 plastic steel pipe The steel plastic pipe is made of the common galvanized pipe and is lined with plastic pipes. With the steel pipe steel pipe strength, stiffness and plastic pipe corrosion resistance, no pollution, smooth wall, small water resistance and other advantages, to achieve the perfect combination of the steel tube and the plastic tube, completely solve the yellow water and the pipe scaling problems, ensure the quality of water supply. Steel plastic pipe has superior performance and price ratio, and can be replaced directly with the ordinary galvanized pipe with the largest amount of domestic consumption. It is one of the most popular pipes to be accepted by the people at present. Its main features are as follows: 1) high corrosion resistance: high quality plastic pipes (PE, PPR and PVC) used in inner pipes, which are sanitary and safe, and have no adverse effects on human health. Highly corrosion resistant and able to withstand general alkaline chemicals. 2) the inner wall of the steel pipe is smooth: the lining of the pipe is extremely smooth and can effectively reduce water loss. 3) no pinholes and cracks: lining plastic pipes of good quality, uniform thickness, never produce pinholes and cr
