Spanning three links

Crossing the tee is one of the tee, and it is also a kind of prefabricated directly buried insulation pipe. It is the branch of branch pipe to avoid adjacent parallel pipes, and increase the size and structure of branch pipe. The spanning three-way pipe is connected by three-way straight pipe and three-way branch pipe. The two ends of the three-way straight pipe have guiding angle. The end of the three-way branch pipe has flange. The end face of the flange has installation hole, sealing line and arc groove. The connection between the flange and the three-way branch pipe is provided with reinforcing ribs.

Component:

1 steel pipe part three way 45 degree elbow nozzle

2 polyurethane rigid foam insulation layer

3 high density polyethylene external protective layer

The utility model is generally used for raising the branch pipe elevation, crossing pipelines or obstacles, and is generally used in conjunction with the plane tee and the Z-type crossing pipe. Spanning three passes, depending on the diameter of the pipe to reinforce. The seamless steel pipe can be directly connected when the applicable pressure of the three-way crossing reaches PN2.5, and the reinforcement should be considered when the welded steel pipe is used. The reinforcement is usually strengthened by a single reinforcement, and the diameter of the reinforcement is 1.5 times the thickness of the branch pipe of the three-way crossing.

It is divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon lapping, pvc, etc.

It is divided into production methods: top, pressing, forging, casting and so on.
