Introduction to Pipe Thickness Pipe Wall thickness is all about having the inside dimensions (ID) and the outside dimensions (OD) which allow you to figure out the wall thickness. You would need to subtract the ID from the OD and then divide by two. This number is the wall thickness.This Course has been organized into 7 lectures & is explained in an organized way.
