How to choose the specification of reducing tee

Usually, when choosing the specification of reducing tee, you need to know what pipeline and what pipe fittings are used through the drawings, and you need to understand the construction model and the current execution experience. For example, we will not use reducing tee for drainage pipes, even if the connected branch pipe is smaller than the main pipe, it can only be reduced by filling the core; as for the elbow, the typical requirement is that the pipe larger than DN100 is turned 90°. Bend, only use two 45° elbows.

In principle, the location where reducing tee is usually used can also use the combination of ordinary tee and reducing diameter, but this is very expensive and unnecessary. At this time, it is the most suitable to use reducing tee. The diameter of the reducing tee and the tee are different, for example, the top and bottom of the riser are de110, and the horizontal branch pipe is marked with de75. This is the reducing tee. The same diameter is the same as this. Therefore, when we operate the reducing tee, we should operate it according to the actual situation when we should operate, and we should accept other tee at other times.
