Line stopping does not necessarily mean stopping the flow. Flow can be controlled while isolating a small section for repair.
Plant Equipment and Maintenance Engineering Handbook
How can this be achieved? Sometimes more than one line stop is needed. When performing a double line stop, different methods of isolation can be used while keeping the pipeline in service. Within a looped distribution system, two line stops are performed.

As a result, the pipeline in need of repair or maintenance is isolated without service disruption. Bypass stopping is used when pipeline maintenance is desired on a transmission main or force main. Many types of pipe can be used when line stopping. These include steel, cast iron, reinforced concrete noncylinder , reinforced concrete cylinder, plastic, AC and nonferrous metals.
Applications for line stopping include: As planners, designers, owners and operators of water and wastewater facilities become aware of these under-pressure control machines and line-stopping methods, they can assist their communities with shutdown and live repair options. Control line stopping offers many benefits to all system contributors: With implementation of these processes, the utility can take control of the system.
All projects must have been in the design or construction phase over the last 18 months. Line-stopper installation Many municipalities and pipeline contractors only use two means of conducting maintenance and repairs to their pipeline: Considering shutdown costs How much does it cost to shut down a system?
The basic process A line-stopping operation includes the following steps: Benefits and applications Many types of pipe can be used when line stopping. Brett Hanes is general manager for Hydra-Stop.
