Line stopping

Line stopping or line plugging is a means of isolating a piping system to provide a shut off where none exists. This process serves as a control, or temporary valve, that can be removed after permanent alterations or valve replacements/additions have been made. With a hot tap previously made on a line, a line stopper is 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. The main is supported by the line stop sleeve. After performing the necessary service, the stop is removed, and a blind flange is installed on the sleeve.
