At the position where the main pipeline needs to branch, make a hole with a precisely calculated size. Wrap the mechanical tee (the main body and the clamp), which is divided into two halves, around the main pipeline to align the outlet with the opening.
There is a specially designed sealing gasket inside to ensure the sealing at the opening. Fasten the two halves of the component with bolts and firmly fix them on the main pipeline by mechanical force. Finally, connect the branch pipe to the outlet of the mechanical tee, which is usually in the form of threads or grooves.
