Discussion on the reasons for the deflation of soft connections at static equipment outlets
Thread Content
Recently, a strange phenomenon has occurred: one of the outlet connections of a storage tank, which has been in use for three years, is experiencing frequent deflation in the rubber flexible connectors that connect it to the pump inlet pipeline. This issue occurs regardless of the liquid level. Please discuss what might be the cause
The tank outlet, flexible connections, and pipes are all DN150 in size. The normal flow rate is below 45 m3/h, so the flow velocity can’t be considered fast, right? ,
The diameter of the tank outlet pipe is DN150, and the actual flow rate is below 45 m3/h. There should also be positive pressure inside the flexible connection; even without a steel wire lining, it shouldn’t collapse, right?
How far from the pump inlet? Has it aged?
If this hose is used regularly without any problems, it is recommended to replace it with a spare first; after installing the spare and eliminating the leaks, then assess the situation further. It’s nothing but leakage and component aging issues. There is a high likelihood of component aging
It’s a little over 1 meter from the pump inlet; no signs of aging were visible.
There isn’t any leakage; it just deflates from time to time, and I’m not sure when it will inflate again on its own.
