Line Stop & Pipe Plugging

Follow us

Our Line Stopping service is a cost effective way of enabling repairs, maintenance, modifications or reconfiguration work on existing piping systems – on either a planned or emergency basis.

Our solution prevents unwanted shutdowns and keeps critical piping and pipeline systems online during tie-ins, relocations, repairs, retrofits and routine maintenance.

Line Stopping halts the flow in an operating pipeline and therefore isolates a section of the “live” pipeline for attention.

During the process, the pipeline can typically be operated under normal conditions when used in conjunction with a temporary bypass. 

Types of Line Stops:

  • Pivoting Head Line Stops
  • Double Block & Bleed Line Stops
  • Folding Head Line Stops
  • Sure-Stops
  • Inflatable Plug Line Stops
  • Custom-made Solid Plug Line Stops
     

We offer Line Stopping services for isolating live pipelines in the following size ranges:

  • Pivoting Head High Pressure Line Stops from 3” to 48”
  • Double Block & Bleed Line Stops from 3” to 48”
  • Folding Head (Low/Medium) Pressure Pipe Line Stops from 12” to 84”
  • Sure-Stop Positive Sealing Line Stops from 1” to 42”
  • Low Pressure Line Stopping using Inflatable Plugs
  • Line Stopping using custom-made Solid Plug Line Stops
