Hello Everyone,
We are doing some work on a pump system (main pump and booster) that is pressurizing up to final pressure of 1700 kPa and moving a slurry initially at ambient temperature. The piping is 20" diameter and there are to be flex hose connections between the intakes and the discharges of the pumps and the piping.
I have worked with flex hose connections between pumps and piping before, but only with much smaller lines. Using Caesar II, I typically allow both the end of the piping, where the flex hose begins, to be free and check displacements to ensure that the flex hose isn't forced to bend any more than minimum bend radius. I assume that any reactions transferred between the hose and the flange of the pumps are negligible.
When dealing with larger diameter piping and flex hose, is the method I use for small diameter appropriate? The length of the flex hose is in the 10-15 foot range.
Thank-you,
Charles
