新型建筑给水管材的选用与施工

Selection and Construction of New Types of Water Supply Pipings

由传统镀锌钢管的缺陷引发出新型建筑给水管材 ,并对其耐温耐压能力 ,线性膨胀系数、膨胀力、热传导系数 ,抗水锤能力 ,造价及安装难易程度进行了技术比较和分类 ,此外 ,根据管道在建筑的三个不同区域的安装特点和要求进行了讨论 ,如各分区主干管、卫生间支管、主干管 。

To overcome the disadvantages of traditional galvanized pipe, new types of water supply piping materials have been developed. Comparison and classification are made based on their characteristics such as thermal stability, resistance to pressure, expansion coefficient and thermal conductivity, resistance to water hammer, cost and easiness of installation. Furthermore, the characteristics were discussed according to their locations in buildings: distribution main line in each pressure zone, branch pipe in water closet and the main line. Finally, the conclusion about the principles for pipe selection according to its location in buildings is given.
