- EN 13445
- PED 2014/68/EU
- ASME IX
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
- International standards: applying ASME, EN and PED requirements for HRSG pressure parts and associated components.
- Material selection: choosing materials suitable for high-temperature and pressure conditions in HRSG service.
Structural analysis and optimisation
- Finite Element Analysis (FEA): verifying component integrity under operational, thermal and mechanical stresses.
- Thermal and mechanical design: evaluating thermal expansion, stress and fatigue to support long component life.
Engineering and design
- Custom component engineering: developing superheaters, evaporators, economizers, preheaters, inlet ducts, stacks and auxiliary components.
- Performance optimisation: engineering components for thermal efficiency, pressure drop and reliable operation.
Manufacturing and fabrication
- Shop fabrication: producing HRSG components in controlled manufacturing environments.
- Quality control: applying welding, dimensional, NDT and material traceability controls throughout fabrication.
Site erection and commissioning
- On-site assembly: coordinating site erection and installation of HRSG components with detailed planning.
- Commissioning support: supporting checks, testing and performance verification during start-up.
Project management and documentation
- End-to-end project oversight: managing engineering, procurement, fabrication and site interfaces.
- Detailed documentation: delivering drawings, calculations, certificates and regulatory documentation.
