Abstract: Automatic line break control is defined as a device that signals, automatically, a valve to open or close when an attached pipeline ruptures or is torn open. As I define the use of the device, it does not depend on a remote or an outside command to operate but has the inherent ability to sense certain phenomena and command the valve to activate itself. With the growing complexity of the pipeline industry, people no longer have time to analyze on the spot all the effects of opening or closing mainline and compressor station valves. In addition pipeline sizes are becoming much larger and are designed to even higher pressures so that the work required to manipulate these valves is more than men physically can handle in an efficient and prompt manner. Living side-by-side with the public and the present awareness of the publics safety make us look much closer at automatic protective devices.
