For high-pressure piping systems where multiple pumps are used together, the problem of water hammer in the piping system is even more acute. Water hammer is a pressure wave of the ever-changing flow in a pressure pipe, which is a hydraulic shock caused by a pressure rise or fall due to the change in the fluid flow rate in the pressure pipe. Water hammer is the combined result of the inc...

What are the main reasons for the damage of the sealing surface of the high-pressure ball valve during its use? Let Dervos introduce it to you! 1.  Mechanical Damage During the opening and closing process, the sealing surface will be scratched, bumped, squeezed and other damages. The atoms between the two sealing surfaces penetrate each other under the action of high pressure, resulting in ad...
