Straight tee and Reducing tee

 The primary purpose of a Tee is to make a 90° branch from the main run of pipe. Standard there are 2 possibilities, on behalf of the equal tee and reducing tee. The equal tee (or straight tee) is used as the branch has the same diameter as the run-pipe.Straight-tee-and-Reducing-teeThe reducing tee is used as the branch has a smaller diameter as the run-pipe.Dimensions...
