HRSG INLET EXPANSION JOINTS
Custom Engineered Solutions Address High Temperatures and Heavy Cycling
Designed for high temperatures and heavy cycling, the HRSG inlet expansion joint is located downstream from the gas turbine diffuser. Integrating advanced composite fabric belt and flanged bolster with steel hardware results in an expansion joint capable of withstanding high temperatures, heavy cycling, and UV deterioration.
An inspection of internal liner plates and retaining stud assemblies will determine the best strategy for replacement or possible retrofit options, depending on the frame and hardware configuration, condition of the internal liners, and the quality of the internal insulation.
PSIG HRSG Inlet Joint Design
- Pre-inspection to determine the best repair, retrofit or replacement strategy
- Custom designs to accommodate high stress, temperatures and heavy cycling
- Repacking the upstream and downstream insulation to reduce the casing temperature and extend the life of the composite fabric belt
