Application of plastic pipes Zhu a feed product structure of various types of plastic pipe, application development trends and domestic and foreign countries for the application of plastic pipe industry policies were introduced, and elaborated the steel skeleton of polyethylene plastic tube performance and features .

Profiles of plastic pipe plastic pipe varieties currently on the market more and more a variety of structures, from (the early 1990s) was originally PVC building drains to a later development of foamed PVC tubes, etc., are at different angles to enter the market. Table 1 is the existing structures and materials of plastic pipe.
