Line Stop / Pipeline Isolation

Line stopping provides a safe, efficient, and reliable method to temporarily isolate sections of a pressurized pipeline—allowing maintenance, repair, or modification without the need for a complete system shutdown.

Our line stopping services are suitable for a wide range of applications across distribution and transmission pipelines.

Capabilities:

  • Size Range: 2” to 48”

  • Pressure Rating: Up to Class #600

  • Temperature Range: 180°C to 280°C

  • Applicable Services: Oil, gas, water, and process pipelines

This method ensures minimal downtime, continuous service to unaffected areas, and enhanced safety during pipeline interventions.

Types of Line Stopping Techniques

We offer a comprehensive range of line stop methods based on pipeline conditions, operating pressure, and client requirements:

  1. Single Line Stop – Used for simple isolation of a single section of the pipeline.

  2. Double Line Stop (Without Bypass) – Provides a more secure isolation using two plugging heads, allowing work between two stop points.

  3. Double Line Stop (With Bypass) – Allows uninterrupted flow by maintaining product transfer through a bypass line while work is performed.

  4. Line Stop Through 3-Way Tee – Used where space or configuration requires isolation through a 3-way fitting, minimizing modification to existing lines.

  5. Low Pressure Folding Line Stop – Designed for low-pressure pipelines, this compact system is ideal for temporary isolation under safe conditions.

  6. Petersen Inflatable Line Stop – A quick-deploy inflatable plug system used for low-pressure or emergency isolations.

  7. Double-Double (Four-Point) Line Stop – Provides complete isolation of a section using two double line stops, ensuring maximum safety for complex operations.
