摘要： An apparatus for temporarily blocking fluid flow through a pipe comprises a housing configured to enclose a portion of a pipe and a flow blockage device. The housing includes a first part defining a housing chamber for receiving the pipe, and a second part defining a stowage space adjacent the housing chamber. The flow blockage device is movable through an aperture formed in one side of the pipe to an installed position in the housing chamber. The flow blockage device includes an outer sealing part that is configurable between an unexpanded configuration allowing the flow blockage device to pass through the aperture and allowing fluid flow through the pipe and an expanded configuration configured to block fluid flow through pipe by substantially preventing passage of fluid between outer side surfaces of the flow blockage device and inner surfaces of the pipe.
