Bengaluru, India Quest Global Full time

-

  • Design and develop steam turbine casings (HP, IP, LP) and exhaust hoods, including both horizontal and vertical split configurations.

  • Define design specifications considering steam pressure, temperature, mechanical loading, and thermal cycling.

  • Create casting-friendly designs suitable for foundry manufacturing, ensuring structural integrity and inspectability.

  • Design flange joints, bolting layouts, alignment features, and gasket interfaces to ensure pressure containment and ease of assembly.

  • Integrate design provisions for instrumentation and controls, including thermowells, drain piping, pressure tappings, and casing relief devices.

  • Perform thermal and structural analysis using FEA tools to assess wall thickness, thermal gradients, and stress distribution.

  • Evaluate casing behavior under steady-state and transient conditions, including startup, shutdown, and emergency load rejection.

  • Design exhaust hoods with appropriate flow paths, structural support, and drain management features.

  • Ensure casing configurations support rotor clearances, steam sealing, and accommodate controlled thermal expansion.

  • Coordinate with controls engineering to define monitoring points and interlocks related to casing metal temperature and drain conditions.

  • Incorporate safety and operational features such as overpressure protection, pressure relief, and proper casing drainage.

  • Select suitable materials (e.g., steel castings, chrome-moly alloys) based on design criteria, thermal properties, and operating environment.

  • Support casting simulations, heat treatment processes, and manufacturing inspections (NDT, hydrotesting).

  • Define tolerances and fit-up conditions to ensure accurate assembly and reliable rotor-casing alignment.

  • Develop 3D models, 2D manufacturing drawings, and BOMs using CAD and PLM systems (NX, Creo, Teamcenter).

  • Interface with turbine rotor, bearing pedestal, piping, and insulation teams to ensure integrated system design.

  • Assist field engineering during installation, alignment, commissioning, and troubleshooting of casing-related issues.

Participate in root cause analysis for casing failures such as distortion, cracking, or leakage in operational turbines
