Background Art

Tee pipe fittings are a type of pipe connector, used at the branch pipe of the main pipeline. They are divided into equal diameter and different diameter. Most common tee pipe fittings are "T" shaped structures. During the production process of tee pipe fittings, the inner wall of the tee pipe fittings is uneven after production, so it is necessary to grind the inner wall.
