ALFA CORE & RASIS  Engineering Excellence for Industrial Impact

ADVANCED ONLINE LEAK SEALING

  • ALFA CORE Saudi Arabia, the parent company of RASIS Egypt, provides ADVANCED high-standard Non-Destructive Testing (NDT) services across the oil & gas, petrochemical, and refining industries in Egypt and the MENA region.
  • Our certified teams operate under ASNT and API standards, with proven expertise in both onshore and offshore inspections, including rope access solutions for high-elevation operations.
What is Online Leak Sealing?
  • Online Leak Sealing is a non-intrusive technique used to seal active leaks in pressurized pipework without shutting down operations or depressurizing the system.
  • It is especially useful in critical industries such as oil & gas, energy, and manufacturing where system downtime is costly or unsafe.
  • ALFA CORE Saudi Arabia, the parent company of RASIS Egypt, performs online leak sealing in compliance with ASME PCC-2-2018 Article 306.
How does Online Leak Sealing work?

  • The process typically includes:

  • Initial Consultation & Assessment

  • Each leak is unique. A custom solution is developed based on the pipe’s size, material, contents, pressure, and temperature.

  • Material & Bracket Preparation

  • Leak-sealing compounds are selected based on the situation. If required, specialized brackets are custom-manufactured.

  • Sealing the Leak

  • The sealant is applied while the system remains operational. Brackets are installed if needed to secure the seal. These may be removed later or left in place long-term.

  • Post-Sealing Monitoring

  • The sealed area is monitored regularly to ensure long-term effectiveness and safety.

  • We use proprietary leak-sealing compounds formulated in-house.

  • These compounds handle a wide range of leak types—steam, chemical, hydrocarbon, and gas—across extreme conditions:

  • Temperatures from -100°C to 800°C

  • Pressures up to 250 bar

  • All solutions are developed, tested, and manufactured at ISO 9001 and ISO 14001 certified facilities.

 

What are the benefits of Online Leak Sealing?

  • No shutdowns required – operations continue uninterrupted

  • Minimized energy loss and environmental impact

  • Enhanced safety by preventing escalation of leaks

  • Rapid response and customizable solutions

  • Cost-effective compared to full system shutdown or replacement

  • Compliance with international standards (ASME PCC-2)

Where can Online Leak Sealing be applied?

  • This solution is ideal for systems with pressurized pipelines carrying fluids or gases in:

  • Refineries

  • Power plants

  • Petrochemical facilities

  • Water treatment plants

  • Manufacturing industries
