The Selection and Construction of New Types of Pipe Materials of Water Supply System in Buildings

摘要

From the drawback of traditional galvanized pipe educe the new types of water supply piping materials, and make comparison and classification from these characteristics such as resistance to temperature and pressure, expansion coefficient, thermal conductivity, resistance to water hammer, cost, installation. Furthermore, discuss from three aspect according to the different portion in buildings: distribution main line in ever pressure zone, branch pipe in water closet, main line. Finally give the conclusion.
