Abstract: A system and method for remote detection, marking and/or sealing leaks in pipe or duct networks are provided. Aerosolized sealant particles that have a surface tackiness that diminishes over time are introduced into the pipe interior. A pressure differential is created and the micron scale particles adhere to the leak edges and to other particles as they are brought to the leaks and then leave the gas streamlines. Control of particle size, drying rate and particle residence time in the pipe interior allows control over the treatment area so that leaks are sealed in the pipes without sealing purposeful openings such as pilot lights or gas valves. This control also produces seals in duct systems with minimal tack at the time the duct systems are returned to service. Particles that do not participate in the formation of a seal can be collected or flushed through the system.

Abstract: In accordance with the resent invention, there is provided a fugitive emission detection system for use in conjunction with a valve having a packing deign which includes a primary packing and a secondary packing. The valve further includes a leak port which is disposed within the valve bonnet between the primary and secondary packings.

In the event of that a prescribed level of fluid leakage beyond the primary packing is detected, the leak port will be closed. The closure of the leak port facilitates the pressurization of the secondary packing.

Abstract: An in-dispenser leak pan provided inside the housing of a fuel dispenser. The leak collection chamber collects any fuel that leaks from fuel-handling components located inside the fuel dispenser above the pan.

If a leak is detected, a control system may generate an alarm and/or cause the submersible turbine pump to stop supplying fuel, or cause the dispenser product line shear valves to close, thereby only stopping fuel flow to the individual fuel dispenser containing the leak.

Abstract: A method of patching a well or a pipe by hydroforming a tubular metal patch. A tool provided with a pair of inflatable packers is inserted inside the patch. The pair of inflatable packers are axially spaced apart from each other by a distance that is substantially equal to the length of the patch.
