Purpose: Three sockets with different directions (such as 45° and 90°) are used for complex pipeline diversion.

Installation steps:

Locate the tee according to the designed angle and mark the length of each pipe section.

Glue the three sockets in sequence (curing in order: install the two ends first, and then the middle branch).

Precautions:

- Thermal expansion compensation: expansion joints are required at the branches of long pipes.

- Angle deviation: The angle needs to be checked after installation, and the error > 5° needs to be adjusted.

- Pressure concentration: The local stress of the special-shaped tee is large, and the recommended pressure is ≤0.6MPa.
