The drain pipe is resistant to corrosion, does not rust, does not foul, has a long service life, and has low maintenance costs. Due to the variety of colors and neat appearance, the quality of interior decoration can be improved and the indoor environment can be improved. The weight of the plastic drain pipe is only 1/7 of the cast iron pipe, the installation labor intensity is low, the construction is convenient, and the work efficiency is high.
