Line Stops and Pipe Stopple Servicesline stop Procedures:
A. Hot tap water line or any type of fluid in pipeline and retain the coupon first. Next, the line stop machine is attached to a temporary valve and the valve is opened. Line stop is hydraulically or mechanically pushed into line to plug the pipe.
B. There are various types of line stop/stopple heads. The type illustrated in the picture on the left can hold pressures ranging from 1000 psi. A single line stop can be used to temporarily stop and abandon a pipeline.
C. Two or more line stop/stopples can be used in conjunction to isolate and bypass many intersecting lines at once. Fluid in the line is bypassed, leaving a workable dead section, in which, alterations, repairs, or valve additions can be achieved, while service provided by the line is continued.
D. When the required work is completed, and the line stop/stopple is removed from the pipeline. The completion machines are installed onto the temporary valves. An IFT completion plug is installed into the outlet flange of the line stop/stopple fitting. This allows the line stop/stopple machines and temporary valves to be removed. A blind flange is usually installed to finished the line stop operation.
