  • Depressurizing a branch pipe
    Patent number: 11860623
    Abstract: A method for depressurizing a pipe includes forming, by an ejector assembly, a seal between a first pipe and a second pipe fluidically coupled to the tee pipe fitting. The first pipe flows a first fluid at a first pressure, and the second pipe flows a second fluid at a second pressure lower than the first pressure. The ejector assembly includes a nozzle converging along a flow direction of the first fluid flowing in the first pipe, and a mixing chamber at an outlet of the nozzle, the mixing chamber comprising an outlet is in fluid communication with the second pipe. The method also includes flowing the first fluid from the first pipe into the ejector assembly through the nozzle so that the pressure of the first fluid decreases to a third pressure lower than the second pressure to draw the second fluid into the mixing chamber.
