Linestop Procedures

Linestop Procedures:

A. Hottap on the line is previously made, the linestop machine is attached to a temporary valve and the valve is opened. Linestop is hydraulically or mechanically pushed into line to plug the pipe. Click the following link for more information about our hot tapping, hottap, wettap, pressure tap services. B. There are various types of line stopping heads. The type illustrated in the picture on the left can hold pressures ranging from 1000 psi. A single linestop can be used to temporarily stop and abandon a pipeline. The other types of line stopping equipment can be found here: Linestop, stopple, pipe plugging machines. C. Two or more linestops 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. Click the following link for more information about our pipeline by-passing services. D. When the required work is completed, and the linestop is to be removed, completion machines are installed onto the temporary valves. An IFT completion plug is installed into the outlet flange of the linestop fitting. This allows the linestop machines and temporary valves to be removed. A blind flange is usually installed to finished the linestop operation. More details can be found about our Completion plug assemblies.
