By Jrbott: Install a water hammer unit in the line to absorb the shock wave. Water hammer commonly occurs when a valve is closed suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe. (PPI) today announced new, free, on-line plastic pipe pressure design software for water distribution, transmission main systems and force mains. When flow is suddenly stopped, flow inertia causes a pressure surge at the valve, with a shockwave propagating through the pipeline. This is also known as Water Hammer and can cause considerable damage. A boiler in the school proved to be the cause, which is why Braun stresses the need to look carefully at larger users in the system. Thirdly, a broken drain pipe could allow waste-water to exit the plumbing system. Now the pipeline operator is able to log onto the Internet, establish a cellular link with the TP-1, review the system performance, and upload data and communicate with the TP-1Remote. Take preventive measures to minimize the impact of water hammer to the pipe lines by way of design and selection of the right equipment 6. It may also be known as hydraulic shock. Excess water pressure can also cause this so have your plumber check the water pressure in the system. Whatever the quality or thickness of insulation, there will always be a level of heat loss, and In severe cases, waterhammer may fracture pipeline equipment with almost explosive effect, with consequent loss of live steam at the fracture, leading to an extremely hazardous situation. The original TP-1 Transient Pressure Monitoring The image to the left depicts a water hammer event with pressure rising from a full vacuum to 260 psi and back to zero in a time span of 0.052 seconds, in a pipeline operating normally at less than 20 psi. Hammer pressure is also caused by air pockets in the pipe, which can enter during city works on the main water lines. With steam systems, this loss of energy represents inefficiency, and thus pipes are insulated to limit these losses. 5, 2013 – The Plastics Pipe Institute, Inc.
