Line stopping is a specialized pipeline isolation technique that temporarily blocks flow in a section of pipeline without requiring a complete system shutdown.
This method allows maintenance, repairs, upgrades, and tie-ins to be completed while minimizing operational disruptions and production losses.
Our line-stopping services are widely utilized in oil & gas, petrochemical, power generation, utility, and infrastructure projects.
