Siemens 191 Repair & Service Capabilities

We address the most common wear and failure modes of Siemens 191 turbines using a combination of advanced repair techniques, performance coatings, and precision engineering. Every project is backed by detailed inspections and rigorous quality assurance.

Rotor & Hot Gas Path Restoration

The rotor and hot gas path (HGP) components are core to the performance of the Siemens 191 turbine. We perform complete rebuilds and advanced restorations to extend service life, improve thermal efficiency, and prevent critical failures.

Key services include:

Rotor disassembly, inspection, and precision rebuild
Blade, vane, and ring segment restoration or replacement
HGP refurbishment with high-temperature and erosion-resistant coatings

Combustion & Structural Component Repairs

Maintaining combustion stability and restoring structural integrity are essential for long-term turbine reliability. Our team repairs and upgrades combustion systems and structural components using precision welding and machining techniques.

Capabilities include:

Combustion system inspection, tuning, and component upgrades
Casing and diaphragm weld repair and precision machining
Sealing surface restoration and alignment correction

Advanced Inspections & Diagnostic Support

We use industry-standard inspection protocols to evaluate critical turbine components and identify signs of fatigue, distortion, or wear. These insights guide proactive maintenance and minimize unplanned downtime.

Inspection services include:

Non-destructive evaluation (NDE)
Runout analysis and vibration diagnostics
Dimensional inspections and tolerance validation

Reverse Engineering & Lifecycle Documentation

When legacy parts are no longer available, we reverse engineer and requalify components to OEM standards—or better. All repairs are backed by comprehensive QA documentation to support regulatory compliance and lifecycle planning.

Support services include:

Reverse engineering of legacy or obsolete components
Material validation and part replication
QA documentation and lifecycle tracking
