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.
