Piping Specs for CADWORX - where to find generic

I am learning about CADWORX right now and want to find somewhere I can get 150 # simple pipe specs so that I can learn about the spec editor and understand how the piping specs work.

Someone mentioned to me that searching online on a forum, someone could point me in the right direction.
Looking for basic, generic 150 # specs that will only be used for learning and not actually building something for construction.

Any help is greatly appreciated.
