On-Line Leak Sealing: A Non-Disruptive Solution for Industrial Leaks (ASME PCC-2 Compliant)
In high-performance industries such as oil and gas, petrochemicals, power generation, and manufacturing, even a small leak can create major safety, environmental, and operational risks. Leaks lead to production losses, unplanned downtime, and costly repairs, while traditional leak repair methods often require complete system shutdowns.
On-Line Leak Sealing offers a safe, efficient, and reliable alternative — allowing leak repairs to be performed without interrupting operations, ensuring continuous productivity and safety. Our solutions adhere to ASME PCC-2 standards, the globally recognized guideline for pressure boundary bolting and leak repair.
What Is On-Line Leak Sealing?
On-Line Leak Sealing (also known as live leak sealing) is a specialized repair method that enables technicians to seal active leaks on pressurized systems while equipment remains in service.
Using custom-designed clamps, precision enclosures, and advanced sealing compounds, leaks in pipelines, valves, flanges, and pressure vessels can be contained effectively — even under high temperature and pressure conditions. All procedures are performed in compliance with ASME PCC-2, ensuring engineering integrity, safety, and long-term reliability.
How It Works
- Assessment: Certified technicians evaluate the leak, pressure, temperature, and service conditions.
- Design: A customized sealing solution is fabricated to fit the component, following ASME PCC-2 recommendations for leak repair.
- Sealing: A high-performance compound is applied or injected under controlled conditions to form a permanent, pressure-resistant seal.
This approach restores system performance without depressurization or shutdown, while meeting international standards for pressure boundary safety.
Advantages of On-Line Leak Sealing
- Zero Downtime: Repairs completed while systems remain operational.
- Enhanced Safety: Minimizes exposure to hazardous leaks and pressure loss.
- Cost-Efficient: Avoids production losses and shutdown expenses.
- Versatile Application: Works for steam, hydrocarbon, gas, and chemical leaks.
- Environmentally Responsible: Reduces emissions and fluid loss, supporting sustainability initiatives.
- ASME PCC-2 Compliant: Ensures repair meets globally recognized pressure-boundary standards.
Applications Across Industrial Sectors
On-Line Leak Sealing is widely applied in:
- Refineries and Petrochemical Plants – leak repairs in compliance with ASME PCC-2.
- Power Plants – high-temperature steam line maintenance without shutdown.
- Manufacturing and Process Industries – continuous production maintained.
- Offshore and Onshore Facilities – live leak sealing for critical systems.
This method supports companies seeking high reliability, safety, and operational uptime across critical industrial systems.
