Sure-Stop – Positive Seal Line Stopping


Sure-Stop Line Stop System

Furmanite’s Sure-Stop Line Stop services provide pipe system control when valves are unavailable or do not operate, and shut-down is not desirable.  While other Line Stop methods seal on the inside of the pipe wall, the Sure-Stop line stop valve intersects the existing header pipe and compresses its seal against a freshly machined cut.

Sure-Stop Capabilities

  • 14″ – 48″ Diameter Pipe Systems
  • Line Stop pressure rating to 500 PSI
  • Available for Line Stopping ANSI Class 150 and 300 pipe systems
  • Positive Flow Stoppage when other Line Stop systems are limited
  • Ideal for work on systems containing flammable or noxious contents when complete Line Plugging shutdown is crucial
  • Additional Safety
  • Works on out of round pipe, pipe with internal seams
  • Effective Line Stop on pipes with known internal build-up of minerals, ash, sludge, or other.
  • Hot Tap Shavings will not limit the quality of the line plugging shutdown like other methods

 

Sure-Stop – Ultimate “No-Shutdown” Control

Furmanite’s Sure-Stop Line Stop is a pipe line plugging system used for providing a positive line stop when having complete line stoppage of flow and product is crucial.  Sure-Stops are often used on flamable and noxious products such as natural gas, petroleum distillates, flare systems, and annhydrous ammonia.

Safe Line Stoppage – When Other Systems Have Limits

Sure-Stop Line Stops provide effective shut-down of flow on pipes that are known to have limitations that can effect the quality of stoppage by other line stop methods.  Common issues that can effect the quality of a traditional line stop are out of round pipes, internal weld seams, heavy internal pipe build up of scale and deposits, and hot tapping shavings.  The Sure-Stop Line Stop method does not rely on sealing on the pipe ID, but rather seals on a freshly machined surface that is “cored” through the existing pipe.  The Sure-Stop Head then intersects the existing pipe and is mechanical expanded, wedging a seal against the pipe wall on all sides.  The compressed seal provides a very fail-safe and postive line stop in most instances.
