Custom High-temperature Resistant Gas Turbine Exhaust Duct with Thermal Expansion Compensation and Optimized Flow-field
Custom gas turbine exhaust pipeline is a key thermal-system component for gas-fired power plants and combined-cycle power units. It connects the gas-turbine exhaust outlet with waste-heat recovery equipment such as HRSG (Heat Recovery Steam Generator). This critical component safely guides high-temperature exhaust gas, compensates for thermal expansion and contraction, reduces heat loss, controls exhaust-gas flow field, and isolates high-temperature radiation.
Well-designed exhaust pipeline improves overall combined-cycle efficiency, protects downstream equipment, and ensures long-term safe and stable operation of gas-turbine power-generation systems. We provide fully customized exhaust pipelines for various models of heavy-duty and industrial gas turbines.
- Grade-matched High-temperature Resistant Material Solution - High-temperature alloy steel and high-strength carbon steel for inner shell, outer shell and supporting structures with high-performance thermal-insulation and refractory lining materials
- Professional Thermal Expansion Compensation Design - Integrated expansion joints/compensators to absorb multi-directional thermal displacement with reasonable support and limit structures
- Optimized Flow-field & Thermal-insulation Structure - Reduced exhaust-gas resistance and pressure drop with multi-layer thermal-insulation structure controlling surface temperature
- Strict Fabrication & Complete Quality Assurance - Advanced welding processes, full-range non-destructive testing, dimensional verification and pressure-related inspection
Suitable for heavy-duty gas turbines, industrial gas turbines, combined-cycle power plants, distributed energy stations and cogeneration projects. Widely applied for new-project supporting, pipeline upgrading & retrofitting, worn-section replacement and performance optimization of existing units.
Please provide gas-turbine model, exhaust-gas parameters, layout drawings or site-condition information. Our engineering team will carry out thermal-mechanical calculation and structural simulation, and deliver customized design scheme as well as competitive quotation within short lead-time.
Scope of Service: New power-plant construction, unit capacity expansion, equipment retrofitting, overhaul replacement and on-site technical modification.
