Line Stop

Line Stops - What Are They?

Line Stopping is a means of temporarily inserting a plugging device to shut off the flow of an in-service piping system. Line Stopping can be used to isolate sections of pipe for repair, maintenance, or reconfiguration such as adding valves. If used with a bypass, work can be performed without service interruptions.

EA Services manufactures a complete High-Pressure Pipe Plugging System for the temporary blockage of pipeline and pipe works wherever a valve is not available. Our standard system is designed for 1000 psig MAOP differential across the plugging head. The EA "Pivoting Head" is the product of decades of expert design enhancement and refinement. With equipment strategically placed around the USA, to cover all sizes of pipe, EA will be there on time.
