Answer 1

Abstract：In recent years, construction of water supply and drainage is the biggest hotspot by the wider use of new pipe. Traditional drainage galvanized steel pipe and the general corrosion of cast iron pipe as easy, since the major transport construction inconvenience and other reasons be replaced. Currently, the construction of drainage pipe used mainly plastic pipe, metal pipe and composite pipe three. Now some of the pipes commonly used, advantages and disadvantages to the use of a brief.
