Line / Flow Stopping / Line Plugging Services
Line Stopping Technology for Utility and Industrial Pipelines
Line/flow stopping is a technique that temporarily halts pipeline flow while allowing a bypass to maintain the supply. In the end enables repairs or modifications with minimal downtime in critical infrastructure.
line stopping services allow maintenance or alterations on pipelines without any interruption in the flow. The technique uses modern hydraulic machinery to isolate the pipeline, forming a safe, controlled and confined work area. It provides consistent isolation in industries and minimises the risks of operation.
As one of the trusted line-stopping providers and subcontractors, PTS supports clients in live pipeline projects by delivering safe, efficient, and downtime-free solutions for both planned upgrades and emergency isolations.

Application
Line-stopping services allow for uninterrupted operations of the pipeline while allowing maintenance, repair, and line modifications. They assist in solving key problems such as leaks and flow diversions without a complete shutdown.
- Pipeline tie-ins connect newly laid sections to existing pipelines without interfering with the flow.
- Valve installations are such that allow changing or installing valves without disrupting operations.
- Flow diversions are used to redirect pipeline flow for system improvement or diversion.
- Leaks and damages are promptly addressed to avert the continuity of pipeline problems.
- Pressure management guarantees safe control during isolation or diversion.
- Emergency response offers immediate intervention to critical pipeline problems.
- Allows isolation for various hydrocarbon pipelines for scheduled or emergency maintenance.

FAQs
What is line stopping?
Line stopping is a technique of stopping a part of a pipeline to carry out repairs or modifications without shutting down the whole system.
What types of pipelines can be used for line stopping services?
The line stopping services can be applied to carbon steel, stainless steel, ductile iron, asbestos-cement, and other pipelines.
What are the pressure and temperature limits for line stopping?
Pipelines with up to 150 bar pressure and temperature from -20°C to 280°C can be used to operate under line stopping procedures.
What are the advantages of line stopping concerning safety?
The advantages are, there is no downtime, and spillage of expensive/toxic products is almost nil, which specifies its safety. Using a proper line stop fitting ensures controlled isolation, which brings in safety.
What factors affect the time required for line stopping?
Factors that affect time are the size of the pipe, material, pressure, site access, and the complexity of the work. Weather and safety conditions may also affect the duration.
