What is the difference between pvc, cpvc, upvc, with explained video orientation and component parts?

uPVC are stronger and better than  pipe but you have to check the company because most of the company's are calling the uPVC as a rigid PVC so it will be the same in this case , and for the CPVC it can take more heat so its used for the hot water lines . 

hope that this is enough . 

when you want to different among three types of pvc ,we must know this  expressions 

** pvc is poly vinyl chloride

**** upvc unplasticized poly vinyl chloride

**** cpvc chlorinated poly vinyl chloride 

In short answer any real work in the field is not in the article
