Crossing tee is used to raise the elevation of branch pipe, cross the pipeline or obstacles, and is generally used in conjunction with plane tee and Z-type crossing pipe. The cross tee is reinforced according to different pipe diameters. When the applicable pressure across the tee reaches PN2.5, seamless steel pipe can be directly connected, and welded steel pipe should be considered for reinforcement. Generally, single reinforcement is used for reinforcement, and the diameter of the reinforcing bar is 1.5 times of the wall thickness of the tee branch pipe.
