Line Stopping
Line Stopping is a method that is used in achieving pipe line isolation, in specific situations where pipe freezing is not possible. For instance, when a system cannot be cooled, or pumps cannot be turned off. This occurs in large organisations such as Hospitals, Hotels or on critical systems that must run continuously.
Instead of Pipe Freezing, a Hot Tap is carried out first on the the pipe that requires isolation. This Follows the same procedure as shown on out Hot Tapping page or in our Hot Tapping guide and downloads.

Once we have completed the Hot Tap, the Line Stop is installed using a valved connection. A specialist kit is then attached, isolation is achieved by installing a “mechanical bung” or balloon into the pipe line. This is done with the aim of stopping the flow of it’s contents. Depending on the situation, a pipe freeze may then be carried out on the flow stopped pipe. This will achieve a 100% isolation, to allow us to safely carry out modifications to the pipe line.
This Line Stopping procedure can be carried out on a variety of pipe materials and sizes. It can also be used to isolate many forms of fluid.
