P22 reducer

P22 reducer (reducer) and its application

The reducer whose center is not on the same straight line is called eccentric reducer

Application of P22 reducer:

In general, concentric reducer can be used, but eccentric reducer is required in the following cases:

(1) Liquid horizontal pipeline to avoid liquid accumulation at low points: use flat bottom

(2) Gas pipeline to avoid high point condensate or gas bag: use top leveling

The installation of the reducer at the pump inlet shall avoid the accumulation of gas at the reducer, and avoid cavitation due to improper installation. When reducing the diameter of the horizontal inlet pipe of the pump, the eccentric P22 reducer shall be selected. When the pipe enters the pump from bottom to top, the reducer shall be flat on the top; When the pipe enters the pump from top to bottom, the bottom of the reducer shall be flat. However, in order to prevent gas from accumulating outside the reducer at the pump inlet, the eccentric reducer also has a flat top installation mode. Even if the pipe enters the pump horizontally from top to bottom, the condensate accumulated at the eccentric reducer can be discharged at the condensate drain valve at the bottom of the filter

For the end or side suction pump with impurities in the transmission medium, when the suction speed is lower than the impurity settling speed, the reducer shall be flat at the bottom
