合理选择给水管道,对提高供水安全性具有非常重要的意义。针对目前管材种类繁多等现状,从管材选择应考虑因素入手,提出了影响因素考虑优先序,并在此基础上,对给水管材在力学性能、防腐蚀能力等方面进行比选,提出了不同情况下管材的选择方案。 Reasonable choice of water supply pipelines is of great importance to improve the safety of water supply. Aiming at the current situation of a wide range of pipe materials, the selection of pipe materials should be taken into account, the influencing factors should be considered in consideration of prioritization, and on this basis, the comparison of mechanical properties and anti-corrosion abilities of water supply pipes should be made. Under the pipe options.
