Features 
 "Ring stiffness" wall in the control loop using a reasonable structure design, greatly improving the pipe ring stiffness, in the same case materials, can withstand greater environmental stress. 
 "Fluid resistance" wall smooth, friction is smaller than concrete pipes, proved in the same slope, the smaller diameter bolt wall corrugated pipe can achieve the same flow rate; in the same diameter, the use of bed wall bellows can reduce the slope, effectively reduce the amount of excavation projects. 
 "Connection tightness" to adopt a flexible ring socket connection, the connection is better than postcards sealing metal pipes and concrete pipe. 
 "Simple construction" and light weight. Length of the large (small connector), and basis for the end of the trench, connecting convenient, quick construction, and lower total cost. 
 "Long life" pipe wear the performance, long service life.
