Line Stopping

Line Stopping is a cost effective way to maintain, modify and repair various types of piping systems without shutting them down. Some applications include replacement or repair of existing valves, damaged or obsolete mains, and creating a permanent or temporary bypass to an existing section of pipe or line while maintaining flow in the main.

Line Stopping is the last alternative before shutting down or draining a piping system. Rangeline provides our Line Stopping Services from 2 inch – 84 inch pipe sizes. Line Stops can be used on all types of pipe materials and products. Here are some examples of the types of pipes, products and applications Line Stopping can be used.

How Line Stop services are performed?

Rangeline Tapping Services produced a detailed animation that illustrates each step of a successful line stop to a working pipeline system avoiding interruption and quickly resolving an emergency pipe break. In this three-minute line stop animation you will get a simple understanding of how Rangeline can help isolate pipe breaks and by-pass around the damaged piping and keep the system up and running with downtime or loss of product or production. Line Stops can solve emergency breaks, repairs or replacements to all types of pipelines including; Ductile/Cast Iron, Steel, PVC, Asbestos Cement, Concrete Pressure Pipes, HDPE, Copper and more. Including all types of mediums such as sewer and water – both chilled and hot.

Line Stop

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.
