Crossing tee is a kind of tee, and also a kind of prefabricated directly buried insulation pipe fitting. It is the product of branch pipe to avoid adjacent parallel pipes and increase the size and structure of branch pipe.

Component: 1 steel pipe part tee 45 ° elbow connecting pipe

2 polyurethane rigid foam insulation layer

3 high density polyethylene outer protective layer

Crossing tee is used to raise the elevation of branch pipe, cross pipe or obstacle, and is generally used in combination with plane tee and Z-type crossing pipe. The cross tee shall be reinforced according to the different pipe diameter. When the applicable pressure of the crossing tee reaches pn2.5, the seamless steel pipe can be directly connected. When the welded steel pipe is used, reinforcement shall be considered. The general reinforcement method is single reinforcement, and the diameter of the reinforcement is 1.5 times of the wall thickness of the tee branch pipe.

Material classification: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PVC, etc.

It can be divided into three parts: top system, pressing, forging, casting, etc.
