This image shows a critical section of the turbine hall where Purna executed the detailed design and engineering of the piping systems associated with the steam turbine, auxiliary equipment and generator. The layout reflects precision engineering to ensure operational efficiency, maintainability and safety within a high-energy environment.
Engineering Scope
1. Turbine and Generator Piping Layout
Purna engineered the routing and support design for all major and auxiliary pipelines around the turbine and generator, including:
- Main steam and extraction steam lines
- Lube oil, control oil and jack oil lines
- Condensate, cooling water and drain piping
- Instrument air and service lines
Each pipeline was modelled to maintain proper clearances, thermal expansion movements and accessibility for maintenance.
2. Support and Restraint Engineering
The piping system required a combination of:
- Fixed supports
- Spring hangers
- Guide and anchor points
- Vibration control supports
These ensured the safe transfer of loads from rotating equipment and minimized operational stresses.
3. Integration With Rotating Machinery
Given the sensitivity of turbine-generator systems, Purna’s engineering involved:
- Isolation of vibration-sensitive pipe sections
- Maintaining nozzle load limits as per OEM requirements
- Ensuring stress-free connections to rotating assemblies
4. 3D Modelling and Clash Management
The entire piping network was modelled in 3D to ensure:
- Zero clashes with structural members, ducts and cable trays
- Safe access for operators and maintainers
- Efficient routing in a congested equipment zone
5. Safety and Operational Considerations
The design incorporated:
- Adequate walkways and maintenance clearances
- Ergonomic valve access
- Safe drainage and venting arrangements
- Compliance with industrial codes and standards
Project Outcome
The engineered piping arrangement ensured reliable turbine operation, simplified maintenance activities and met all mechanical, structural and thermal performance criteria. Purna’s engineering contribution strengthened the overall efficiency and structural integrity of the turbine hall.
