塑料管道在国外应用十分广泛,常用在电气、给排水、工艺管道等方面。尤其是塑料排水管道应用比较普遍,因塑料管道有耐腐蚀、安装方便等优点,基本取代了铸铁管。塑料排水管道的接口方式以橡皮圈接口和粘胶结口比较常见。橡皮圈接口十分简单,将橡皮圈直接放入承口内,用工具将管道打进去即可。这种接口方式的管道,在拆 Plastic pipe is widely used in foreign countries, commonly used in electrical, water supply and drainage, process piping and so on. In particular, the application of plastic drainage pipes is relatively common. Because plastic pipes have the advantages of corrosion resistance and easy installation, they basically replace cast iron pipes.
