Line Stop

          Line stop is the process of isolating a piping system to provide a shut off. This process serves as a control, or temporary valve, which can be removed after alterations or valve replacements have been made. With a hot tap previously made on a line, a line stopper is then attached to a temporary valve, and the valve is opened. The line stopper is hydraulically or mechanically pushed into the line to seal the pipe. After performing the necessary service, the stop is removed, and a blind flange is installed onto the sleeve.

A single line stop can be used to stop off and abandon a shutdown. Two or more line stops can be used in tandem to isolate and bypass many intersecting lines at once. Fluid in the line is bypassed, leaving a workable dead section that could be alter, repair, or add a valve while the service provided by this line is continued.
