| Abstract: | The application of flow limiting orifice in pipeline as safety instrument was studied in this article. The example for filling out the function form for safety instruments was presented. Through the calculation for the orifice under two conditions,the influence of orifice to safety valve was determined. It was indicated that after the orifice is installed,the size of safety valve shall be determined with the maximum flow of the orifice. |
