- 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.
