Line Stopping

Wellube’s 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
