管网作为供排水系统的重要组成部分,其投资在供排水系统建设总投资中占很大比重,可以说管材的选择会直接影响运行、维护成本及服务质量。当前国内市场,管材种类繁多,产品质量良莠不齐,如何在品种繁多的管材中做出科学合理的选择,将管道系统与高质量的生活结合等问题一直困扰着城建规划者、设计专家、施工单位。为使读者更为清晰地了解不同管材的应用情况,本期我刊特邀中国金属学会铸铁管分会、中国塑料加工工业协会塑料管道专业委员会和中国建筑金属结构学会地面供暖委员会的专家谈谈各种不同材质管材的行业状况、应用功能、选用要点、存在的问题及发展趋势。
As an important part of water supply and drainage system, pipe network accounts for a large proportion of the total investment in water supply and drainage system construction. It can be said that the selection of pipe will directly affect the operation, maintenance cost and service quality. The current domestic market, a wide range of pipe, product quality varies greatly, how to make a scientific and rational selection of a wide range of pipe, the pipe system and high quality of life and other issues have plagued the urban construction planners, design experts, construction units. In order to make the reader know more clearly about the application of different pipe materials, this issue I invited Chinese Metal Institute of Cast Iron Branch, China Plastic Processing Industry Association Plastic Pipe Professional Committee and the China Building Metal Structure Society floor heating committee experts to talk about Different kinds of material pipe industry status, application functions, selection points, problems and trends.
