Although there are many advantages of PVC drainage pipes, they are prone to aging problems after being used for a long time, especially for pipes used outdoors, because they will be irradiated by strong light, so they are easy to become brittle and aging, which is very important for its service life. The impact is very large. The PVC drainage pipe will be relatively poor in terms of resistance to mechanical impact, because its expansion coefficient is relatively large, so we must pay attention to this aspect when using it to avoid rupture.
