Diameter pipe applications

Excerpts: 1, when the flow of fluids in pipes changes, such as increasing or decreasing the flow rate requirements changed little, are required to use different-diameter pipe.

2, the inlet of the pump, in order to prevent cavitation, requires the use of different-diameter pipe.

3, with the instruments, such as flow meters, regulating valves joints, in order to fit with the instrument connector, also requires the use of different-diameter pipe.
