摘要
随着社会的发展和水资源分布不均矛盾的加剧,越来越多的长距离输水管道在城乡生活及工农业供水工程中应运而生。在管道工程中,管材的投资一般占工程投资的1/2以上,因此管材选择至关重要。对不同管材技术特性、经济性和防腐方式进行对比分析,为同类工程提供参考。
With the development of society and the intensification of the contradiction of uneven distribution of water resources, more and more long-distance water pipelines came into being in urban and rural life and industrial and agricultural water supply projects. In pipeline engineering, the investment of pipes generally accounts for more than 1/2 of the project investment, and the selection of pipes is very important. To make a comparative analysis on the technical characteristics, economy and anti-corrosion methods of different pipes, so as to provide reference for similar projects.
