在供水管线工程中,管道占投资比重较大,合理选择管材的种类对工程的安全及投资具有重要意义。本文就预应力钢筒混凝土管(PCCP)、玻璃钢管(GRP)、钢管(SP)、球墨铸铁管(DIP)和涂塑复合钢管(TPEP)等5种管材各有自身的优、缺点和适用范围分别进行了论述,应根据工程的不同条件和要求合理选择管材。

In the water supply pipeline project the pipeline accounts for a large proportion of the investment.It is of great significance for the safety and investment of the works to select suitable kinds of pipe during construction.The paper analyzes the advantages,disadvantages and application range of such five kinds of pipe as prestressed steel cylinder concrete pipe(PCCP),glass reinforcement pipe(GRP),steel pipe(SP),ductile cast iron pipe(DIP)and coated composite steel tube(TPEP).The pipe should be reasonably selected according to the different conditions and requirements of the project.
