Our water hammer calculation computes the maximum and minimum piezometric pressures (relative to atmospheric) in each pipe in a pipeline as well as the time and location at which they occur. Introduction. It is possible to have high pressure steam systems operating without water hammer, and a long operational life from the steam components. During cold start up, the rate of condensation in the pipework is higher. Characterized by a series of quick thumps, or a single loud one followed by silence, it occurs only when a valve is suddenly closed. For example, the audible creaking when taps are shut off in kitchens or bathrooms results from the Water Hammer effect. The company's web site has a new feature that lets customers easily determine the water hammer or shock pressure potential of any piping system under consideration. Shock and Surge Tanks are ASME replaceable bladder type pre-charged hydropneumatic tanks for commercial, industrial, municipal and well water systems, to effectively control water hammer shock, and pump start-up/shot-down water surge. What is water hammer? Water hammer is a wave / loud hammer like sound, caused when a fluid in motion is forced to stop or change direction suddenly.

During steam-water direct contact condensation process, a slug flow may appear, which would cause steam condensa- tion induced water hammer (CIWH). In addition, water hammer can be caused by the sudden condensation of steam which reduces its specific volume by more than 1,000 times, so when steam comes into contact with colder condensate and condenses, its volume is instantly reduced to next to nothing. When the steam hits all that water, you get water hammer. "Water hammer" is the unexpected release of high pressure condensate that is then carried at high speeds in a steam pipe until it collides against a valve, or other component.

If there was work between the two the work would move but very little energy would go into the work. It could be that the household water pressure is within the normal limits of pressure but that you have recently installed a new washing machine, dishwasher, or ice maker line and this is causing water hammer. The sliding piston absorbs sudden pressure changes and keeps the pipes from banging. Hot steam hitting cold water (or vice versa) will lead to water hammer. Condensation Induced Water Hammer is a rapid condensation event. When the steam pipe is warmed up and steam comes out through the drain cock, the drain cock can be closed and the steam stop valve can be opened slowly. About 90 percent of all electric power produced in the world is through the use of steam turbines. In mains where the steam and condensate travel in the same direction, there should be a drip line every 150 feet. Water hammer occurs in steam supply and condensate return lines, and there are three basic types: hydraulic, thermal shock and differential. As steam loses heat, it turns back into water. do not mix steam with water either by injecting water into a steam system or steam into a system that includes water (condensate).
