A blowdown valve (BDV) is a type of shutdown valve designed to depressurize a pressure vessel by directing vapour to a flare, vent or blowdown stack in an emergency. BDVs fail-safe to the open position upon failure of the control system. [1] The type of valve, type of actuation and performance measurement are similar to an ESD valve.
The importance of valve leakage depends on what the valve is controlling. For example, a dripping tap is less significant than a leak from a six-inch pipe carrying high-pressure radioactive steam. In the United States, the American National Standards Institute specifies six different leakage classes, with "leakage" defined in terms of the full ...
A gas leak refers to a leak of natural gas or another gaseous product from a pipeline or other containment into any area where the gas should not be present. Gas leaks can be hazardous to health as well as the environment. Even a small leak into a building or other confined space may gradually build up an explosive or lethal gas concentration. [1]
A Larimer County man's 11-month journey to stop leaks at an oil storage facility near his home illustrates gaps in enforcement, conservationists say.
While leaking underground storage tanks are located in nearly every town in the U.S., those who live closest to these sites tend to be in communities that are lower income with a higher proportion ...
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.
These blow-by gases, if not ventilated, inevitably condense and combine with the oil vapor present in the crankcase, forming oil sludge. Excessive crankcase pressure can furthermore lead to engine oil leaks past the crankshaft seals and other engine seals and gaskets. Therefore, it becomes imperative that a crankcase ventilation system be used.
The cause was an explosion following a propane tank leak. [7] On March 1, 1965, the LaSalle Heights Disaster occurred when a gas line fractured in a low-cost residential neighborhood near Montreal, Quebec, killing 28 people and injuring dozens. On January 9, 1968, in Reading, Pennsylvania, an explosion killed nine persons and demolished two ...
