Necking nozzle

The necking pipe, commonly known as reducing pipe, plays a role in controlling the flow and pressure in the heating system. In the heating system, hot water flows out of the main pipe and into thousands of households, and the pipes become more and more divided. If the diameter of the fractional path pipe is not constantly changed, the diameter of the pipe will become larger and larger, and the corresponding pressure and flow rate will slow down sharply. Even an equal pressure loop will be formed in some places, and other pipes will tend to be static. Therefore, reducing diameter will be used in the heating system to change this situation, so that the change of pipe diameter carton can be controlled
