To solve the problem of pipes vibration of large-sized compressor in ammonia plant, orifice plates are installed after thorough analysis of the causes of vibration, effectively solved the problem.

Applying throttle orifice to power plants;

With applying the throttle orifice in power plant,the thermodynamic processes and the physical phenomena is detailed for the steam water flowing through the throttle orifice,and after analysing the reason,this paper described how to calculate the orifice stages number and the orifice diameter,and in the end,the concrete application cases are presented.

In this paper,the influence of orifice-induced pressure head on pit corroded piping is studied.

By using EFS injection test bench,this paper studied the different performance of electronic injector with different type of orifices.

Research on Vibration and Noise Issues of Nuclear Pipesdue to Orifice Cavitation;

Investigation on magnetic oxide iron depositionof throttle orifice plate in once-through boiler water wall

The operating principle of a throttle orifice plate is introduced and its typical application in a forced circulation evaporative cooler of a heating furnace in steel rolling enterprises is presented.

Flow field and structure in throttle orifice plate is systematically analyzed and studied by experiment and locale research, and finally theoretical foundation is provided for design of thrott.
