ABSTRACT:
An automatic pipeline testing and sealing system and method to operate the functions of an inflatable packer device from a remote location. The automatically operated packer device has inflatable end elements, an exterior sleeve member and a chemical dispensing mechanism and is in operative communication with a cable assembly, a compressed air source, a pressurized test fluid source, a sealing chemical component source, and a catalyst component source. The automatic testing and sealing system comprises a first pump in operative communication with the sealing chemical component source and the cable assembly, a second pump in operative communication with the catalyst component source and the cable assembly, a test valve in operative communication with the test fluid source and the cable assembly, and a control panel assembly having electronic circuits for setting and automatically controlling the timing and air pressure parameters of the packer device and to permit the automatic testing and sealing operations of the packer device. The control panel assembly further has electronic circuitry to control the packer device end element pressure, to control the testing and sealing pressures of the packer device sleeve member, and first and second pressure differential sensors to automatically control the activation of the first and second pumps for sealing purposes and to control the test valve for its testing purposes.
