Line Stops

Line Stops are used to temporarily shut down a pipeline system to complete modifications or repairs.
Line Stops allow a system to operate as usual without any interruption of service. Line Stops can be performed on almost any kind of pipe with pressures or product under pressure.

The Line Stop operation consists of a special flanged Line Stop fitting, a temporary valve, and our actuator. The Line Stop fitting is installed and tested, the temporary valve is installed, and the hot tap is completed. After the hot tap, we install the line stop actuator and insert the Line stopping head into the line. When the necessary work has been accomplished, the Line stop head is removed, and the completion plug is set.

The completion plug seals at the flange on the Line Stop fitting and allows us to remove our temporary gate valve. A blind flange is installed on top of the Line Stop fitting and the operation is complete.

The Line Stop fitting can be re-used in the future if needed.
