Hot Gas Path Inspection (HGP)

During the Hot Gas Path Inspection (HGP), our expert technicians conduct a comprehensive assessment of your gas turbine system, focusing on both the combustion components and the turbine sections. This thorough examination ensures that all critical areas of the turbine are inspected and maintained to optimize performance and reliability.

Combustion Inspection:

Our technicians revisit the combustion components inspected during the initial combustion inspection, ensuring that they are still functioning optimally. Any maintenance or repairs identified during the combustion inspection are addressed to ensure continued efficiency and safety.

Turbine Section Examination:

Our inspection extends to the turbine sections of the gas turbine, including blades, vanes, seals, and casings. We meticulously examine each component for signs of wear, erosion, cracking, or other damage that may affect turbine performance.

Clearances and Alignment Check:

We verify clearances between turbine components and ensure proper alignment to prevent rubbing and maximize efficiency. Any deviations from recommended tolerances are noted and corrected to maintain optimal turbine operation.

Blade Coating Assessment:

If applicable, we assess the condition of thermal barrier coatings on turbine blades to ensure adequate protection against high temperatures and corrosion. Any areas of coating degradation or delamination are identified and addressed to prevent further damage.

Benefits of Hot Gas Path Inspection (HGP):

  • Early Issue Detection: The thorough examination of both combustion and turbine sections allows us to detect and address potential issues early, minimizing the risk of unexpected downtime.
  • Optimized Performance: By ensuring that all critical components are functioning optimally, the HGP helps to maximize the performance and efficiency of your gas turbine system.
  • Extended Equipment Lifespan: Regular HGP inspections and maintenance help to extend the lifespan of your gas turbine equipment, reducing the need for costly repairs or replacements.
  • Compliance and Safety: Our HGP inspections ensure that your gas turbine system meets all regulatory requirements and safety standards, providing peace of mind and avoiding potential penalties.
