Flue Gas Ducts
Aras Power Systems designs, engineers and fabricates flue-gas ducts for power generation and industrial exhaust systems. Ductwork is developed for safe gas handling, low pressure drop, structural reliability, thermal expansion control, environmental compliance and long-term service under high-temperature and corrosive operating conditions.
Codes & standards
Aras Power Systems designs flue-gas duct systems to the client-nominated code basis, combining international standards with project-specific operating, safety and documentation requirements.
- ASME
- EN 1090
- EN 1993 / Eurocode 3
- ASME IX
- ISO 12944
Our Services
Our engineering and supply scope is structured to deliver safe, efficient and project-specific equipment from concept design through fabrication, site support and documentation.
Design compliance
- Compliance with standards: designing ductwork according to applicable international mechanical, structural and fabrication standards.
- Customised duct design: tailoring duct geometry, supports, stiffeners, liners and access details to each flue-gas system.
Finite Element Analysis (FEA)
- Structural analysis: verifying ductwork integrity under pressure, temperature, dead load, wind, seismic and support loads.
- Material durability: assessing material response to thermal cycling and chemical exposure in flue-gas service.
Engineering and design services
- System optimisation: engineering duct routing and transitions for improved flow dynamics and reduced pressure drop, supported by CFD where necessary.
- Thermal expansion accommodation: designing supports, guides and expansion joints to handle movement safely.
Manufacturing and shop fabrication
- Precision manufacturing: fabricating duct panels, transitions, stiffeners and accessories in controlled facilities.
- Quality assurance: applying dimensional, welding, coating and assembly checks to meet project specifications.
Documentation and quality assurance
- Comprehensive documentation: providing drawings, calculations, material certificates and manufacturing records.
- Quality inspections: conducting NDT, dimensional inspection and coating checks according to project requirements.
Sustainable and safe operation
- Emission control: designing ductwork that supports effective exhaust handling and environmental performance.
- Safety protocols: incorporating access, inspection and maintenance provisions into the duct design.

Frequently asked questions
Can you design ducts for high-temperature service?
Yes. Ducts are designed with suitable materials, stiffening, expansion allowances, insulation or lining depending on operating temperature and gas composition.
Do you perform CFD for duct systems?
Yes. CFD can be used for pressure-drop control, flow distribution, transition geometry and inlet/outlet arrangement optimisation.
What documents are provided?
Typical deliverables include arrangement drawings, fabrication drawings, calculations, material certificates, welding records, coating reports and inspection documentation.
