Abstract
A system for controlling and extinguishing oil and gas well fires, as well as a system for remotely controlling flow of a pipeline. The system of the present invention encapsulates a section of the pipe, such as beneath the oil and gas well. The encapsulated section of pipe is tapped to bleed off the maximum pressure and flow of the pipe which is diverted to a remote storage reservoir. The upper and lower sections of the encapsulated section of pipe are sealed to allow a valve to be installed in the pipe. The pipe is operated by remote-activation to control the flow to the surface. The flow can thus be stopped to allow the surface facilities to be rebuilt or replaced.
