A high-pressure pressure reduction valve is rarely a simple throttling component. In boiler feedwater, refinery, chemical, and utility service, it must dissipate significant energy without creating destructive noise, vibration, flashing, cavitation, or downstream instability. When [...]

A centrifugal pump can sustain serious internal damage while its driver remains loaded, its discharge pressure appears normal, and the control room sees no immediate alarm. The risk begins when process demand falls below the [...]

A large pressure drop across one restriction can turn a controlled bypass into a destructive operating condition. Flashing, cavitation, high velocity, vibration, and unacceptable noise often begin at the point where pressure energy is released [...]

A pressure-reducing valve can appear to be operating normally while the downstream piping absorbs the real damage. When liquid pressure falls below vapor pressure, flashing begins. The resulting two-phase flow can erode valve trim, elbows, [...]

A centrifugal pump can be damaged long before an operator sees a low-flow alarm. At insufficient flow, internal recirculation, temperature rise, vibration, cavitation, and unstable hydraulic forces can rapidly reduce pump life. Selecting an automatic [...]

A centrifugal pump can be operating below its safe minimum continuous flow long before a flow indication or high-temperature alarm makes the problem visible. At that point, internal recirculation, vibration, temperature rise, hydraulic instability, [...]
