Abstract
In theory, the maximum allowable working pressure of cast iron, with flange specification PN10 and pressure rating KS B1501, is 1.0 MPa. However, in reality, the maximum allowable pressure can be 1.3 MPa if the strength of the materials used and the stability of the bolted joints are considered. The stability of the flange part of a cast iron pipe was confirmed using function test analysis SPS-KWWA-D111. Next, a D900 (denotes pipe diameter) water pipe was modeled based on the combination of a steel pipe and gray cast iron pipe. Subsequently, the streamline, flow velocity, and pressure distribution, when the valve opened and closed based on the general pipe flow rate and discharge pressure, were calculated. Finally, fatigue analysis was performed using the pressure data for the pipeline, to confirm stability.
