Line stopping is a controlled method of temporarily isolating a section of pressurized pipeline without shutting down the entire system
💧 Keep Systems Running – Isolate lines without shutting down operations
💧 Minimize Downtime – Avoid lost revenue from production interruptions
💧 Safety First – Protect workers, property, and the environment
💧 Prevent Leaks & Spills – Zero-release protocols for environmental protection
💧 Live Repairs & Upgrades – Perform critical maintenance without full shutdowns
Benefits of Line Stopping
How It Works
Line stopping uses a controlled access point on a pressurized pipeline to temporarily isolate a section of pipe without shutting down the entire system. This allows critical repairs, upgrades, or reroutes to be completed while service remains active.
How Line Stopping Is Performed
Line stopping is a precise, controlled process performed by trained technicians using specialized equipment.
-
System Evaluation & Planning – Assess pipe size, material, pressure, flow, and job scope.
-
Access Preparation – Create controlled access points for line stop equipment.
-
Line Stop Installation – Install fittings and position the line stop head.
-
Isolation Verification – Expand the plugging head to fully isolate the targeted section.
-
Work Execution – Perform repairs, replacements, or reroutes while the system remains active.
-
Removal & Restoration – Remove equipment, install permanent completion fittings, and restore full service.
APPLICATIONS OF LINE STOPPING
Line stopping is used to temporarily isolate sections of active pipeline systems to support planned work and unplanned conditions without shutting down the entire system.
Common applications include:
-
Water and wastewater main repairs
-
Valve installations and replacements
-
Pipeline reroutes and tie-ins
-
Emergency isolation for leaks or failures
-
Infrastructure upgrades and rehabilitation
This method allows work to proceed while maintaining service continuity for customers and operations.
PIPE MATERIALS & SYSTEMS
Line stopping can be performed on a variety of pipe materials and system configurations, subject to project evaluation and approved procedures.
-
Supported pipe materials include:
-
Ductile Iron
-
Cast Iron
-
Steel
-
PVC
-
Asbestos Cement
-
PCCP/RCCP
-
HDPE
-
Applicable systems:
-
Transmission mains
-
Distribution lines
-
Pressurized water and wastewater systems
All applications are evaluated based on pipe condition, pressure, flow, and project requirements.
