At Core Pipeline Services, we specialise in hot tapping and line stopping services in South Africa, providing engineered solutions for modifying, isolating and maintaining live pipeline systems without unnecessary shutdowns.

Our specialist pipeline services are designed to help clients maintain operational continuity while safely carrying out pipeline connections, repairs, modifications and sectional isolation.

With a focus on integrity, precision and professional execution, Core Pipeline Services provides hot tapping and line stopping solutions tailored to the requirements of each pipeline and project.

Hot Tapping Services

Hot tapping, also known as pressure tapping, allows a new connection to be made to an existing pipeline while the pipeline remains in service.

This specialist procedure can eliminate the need for a complete system shutdown for certain pipeline modifications, helping minimise disruption, downtime and operational interruptions.

Our hot tapping services can be used for:

• New pipeline branch connections
• Pipeline tie-ins and modifications
• Installation of valves and fittings
• Pipeline extensions
• Bypass connections
• Access points for line stopping
• Pipeline maintenance and upgrades

How Hot Tapping Works

A successful hot tapping operation requires careful planning, suitable equipment and controlled execution.

1. Pipeline Assessment
The existing pipeline and operating conditions are assessed to establish the appropriate hot tapping arrangement.

2. Fitting Installation
A suitable fitting is installed onto the existing pipeline to create the connection point for the hot tap.

3. Valve Installation
A suitable valve is installed between the pipeline fitting and the hot tapping equipment.

4. Pressure Testing
The connection and valve arrangement are checked and tested as required before the tapping operation.

5. Hot Tapping Operation
Specialised equipment is used to cut through the existing pipe wall while the pipeline remains in operation.

6. Completion
The cutting equipment is retracted and the valve is closed, leaving the new pipeline connection ready for the next stage of the project.

Line Stopping Services

Line stopping provides a controlled method of temporarily isolating a section of an existing pipeline while allowing other parts of the system to remain operational.

It can be used where conventional isolation is unavailable, impractical or insufficient for the required pipeline work.

Our line stopping services can support projects involving:

• Pipeline repairs
• Valve replacement
• Pipeline modifications
• Sectional isolation
• Pipeline relocation
• Pipeline upgrades
• Maintenance on live pipeline systems
• Temporary bypass arrangements

How Line Stopping Works

Line stopping is typically carried out using a hot tap to create an access point into the existing pipeline.

1. Hot Tap Connection
A suitable hot tap is completed on the pipeline to provide access for the line stopping equipment.

2. Line Stop Equipment Installation
The line stopping equipment is securely installed onto the hot tap connection.

3. Pipeline Isolation
The stopping head is introduced into the pipeline and positioned to isolate the required section.

4. Maintenance or Modification
Once the required section has been isolated, the necessary repair, replacement or modification work can be carried out.

5. Removal & Completion
Once the work is complete, the line stop is removed and the pipeline connection is completed in accordance with the project requirements.

Hot Tapping & Line Stopping: Working Together

Hot tapping and line stopping are often used together when a section of a live pipeline needs to be isolated without shutting down the entire system.

A typical application may involve hot tapping at strategic points on the pipeline, followed by line stopping to isolate the section requiring work.

This can provide a practical solution for projects where maintaining flow through the wider system is important.

Applications can include:

• Pipeline section replacement
• Valve replacement
• Pipeline relocation
• System modifications
• Temporary bypass installations
• Pipeline repairs
• Infrastructure upgrades

The required configuration depends on factors such as pipeline size, operating pressure, temperature, product, pipe material, location and project requirements.
