铜水管是水、气管道的 最佳选择 铜水管、气管由于它自身的众多优点,与镀锌管、塑料管、铝塑管等相比较,铜管是水道管的最佳选择。首先,铜水、气管的使用寿命长,一般超过50年或者更长,可做到“一次安装,终身受用”。北京协和医院20世纪20年代安装的铜水管至今依然良好,就是最好的证明,而其他类型的水、气道管的使用寿命大都在10～20年以内。其次,铜水、气管的强度高,塑性韧性好,导热(电)性优,易于加工而且抗压、抗碰、防水,是各类水道管中最安全的。第三,铜的耐腐蚀性、抗氧化性和抗渗透性强,能抑制细菌 Copper water pipe is the best choice of water and gas pipe Copper water pipe, trachea Because of its many advantages, compared with galvanized pipe, plastic pipe, aluminum pipe, copper pipe is the best choice for water pipe. First of all, copper water, the long life of the trachea, generally more than 50 years or longer, can be “once installed, life-long use.” Beijing Union Medical College Hospital installed in the 1920s, copper pipes are still good, is the best proof, and other types of water, airways tube life mostly in 10 to 20 years. Second, copper water, high strength trachea, plastic toughness, thermal conductivity (electricity) is excellent, easy to process and compression, anti-collision, waterproof, is the safest water in all types of pipe. Third, copper corrosion resistance, oxidation resistance and permeability, can inhibit bacteria
