Our Core Capabilities


On-Line Leak Sealing Live Leak Repairs Compound Injection Custom Enclosures Zero Downtime Solutions

Zero Downtime. Zero Compromise. Sealing Critical Leaks Without Shutdowns.

Service Features

Comprehensive capabilities and specialized services

Live Sealing at Extreme Conditions

  • Leak repairs under up to 10,000 psi and 650°C / 1200°F across pipelines, vessels, and valves.

Three-Stage Leak Sealing Process

  • Includes custom-built clamp, precise injection system, and long-lasting sealant fill for total containment.

Compound Injection Technology

  • High-pressure injection guns deliver sealant/compound into custom enclosures, bonding within leaks to form durable seals under extreme heat, pressure, flow, and media.

High-Reliability Across Systems

  • Compatible with steam, hydrocarbons, chemicals, and pressurized water lines.

Engineered Enclosure Solutions

  • Welded or mechanical enclosures designed to encapsulate the exact leak geometry.

Zero Interruption to Operations

  • Keeps your plant running, product flowing, and processes intact during repairs.

Environmental & Energy Benefits

  • Reduces emissions, noise levels, and product waste.

Component Life Extension

  • Prevents escalation of defects, preserving valuable assets and avoiding shutdown planning.

ASME PCC-2 Compliant Workmanship

  • Our procedures and materials follow international codes for safe, reliable containment.

Full Engineering & Documentation

  • Every seal includes pre-job analysis, custom design, QA/QC reports, and final certification for compliance.

Pipes & Weld Joints

  • Repairs of through-wall defects, pinholes, cracks and erosion damage without cutting or isolating lines.

Flanges, Couplings & Unions

  • Custom clamp-and-seal solutions for leaking gasket joints or deformed flanged connections.

Valves & Bonnet Seals

  • Live leak containment at valve stems, glands, and bodies—even under full process load.

Expansion Joints & Tees

  • Flexible containment methods for high-stress fittings, offset joints, and complex geometries.

Pressure Vessels & Static Equipment

  • On-line sealing of nozzles, shell leaks, and weld zones—especially in reactors and column systems.

High-Pressure, High-Temp Media

  • Proven sealing across extreme-duty lines including steam, hydrocarbons, acids, solvents, and high-velocity water.
