Pipe plugs are used with supplementary accessories such as air and water hoses, air and pressure control devices, gauges, adapters and chains depending on the type of the pipe plug and the process. Auxiliary equipment like compressors for inflating the pipe plugs, water tanks for filling the pipeline and pumps for some cases must be used.
A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection , and pressurization of the vessel to the specified ...
A plug in sanitation is an object that is used to close a drainage outlet firmly. The insertion of a plug into a drainage outlet allows the container to be filled with water or other fluids. In contrast to screw on caps, plugs are pushed into the hole and are not put over the hole.
Escaping liquids create an acoustic signal as they pass through a hole in the pipe. Acoustic sensors affixed to the outside of the pipeline can create a baseline acoustic "fingerprint" of the line from the internal noise of the pipeline in its undamaged state. When a leak occurs, a resulting low-frequency acoustic signal is detected and analysed.
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
A solution to prevent manholes to be uplifted is to create drain plugs throughout a manhole wall. The plugs have screens to prevent dirts but allow water to drain through. The pressure-sensitive plugs are calibrated to hold water up to a certain pressure level which is higher than normal ground water pressure.
