Line Stops which are sometimes referred to as stopples are used to completely stop the flow and hold back the pressure of a pipeline. This is done using a plugging head or completion plug through a hot tap and fitting connected to the pipeline.
Two sets of line stops and piping connected to them can divert the flow around a problem area within a pipeline so that the flow in the line is never interrupted and the problem area can be isolated, repaired or altered.
EnReach uses several different types of line stops depending on the pressure, temperature, and product in the line.
|Sizes||2″ through 28″|
|Pressure||Up to 1480 Psi|
|Temperature||Up to +177 ° C|
|Double block and bleed style available|
|Available for Steel, HDPE and PVC pipelines|
|Meets low temperature requirements|
|Meets sour service requirements|
|Pressure, temperature, size and product in the line determine what line stops are used and if a double block and bleed system is available for those conditions. All line stops are reviewed on a per job engineering assessment.|
