摘要
分析了传统管材———镀锌钢管———的特点 ,指出其弊端及新型管材取代镀锌钢管的必然性 .介绍了新型管材的种类、特点 ,通过对技术参数、性能、价格及施工等方面的分析比较 ,提出了在实际工程设计、施工中应多方面进行综合对比 。
The characteristic of traditional tube galvanized steel pipe is analyzed,its defect is pointed out and it is necessary to the new type piping materials replace galvanized steel pipe.The characteristic and the kind of the new type piping materials are introduced,by way of to the new tube at the aspect of technology parameter,capability,price and constructions,etc.The many sides to carry on the synthetic contrast in engineering design and construction are put forward,and the suitable tube is selected.
