Product Description
A turbocharger casing is more than a shell; it is a pressure vessel operating under intense heat and mechanical stress. At Sourcing Marine, we supply casings manufactured from high-silicon molybdenum (SiMo) cast iron or equivalent specialized alloys to ensure structural stability at temperatures exceeding 600°C.

Technical Design & Manufacturing Standards
- Volute Geometry Optimization: Our casings maintain the precise internal volute profiles required to convert exhaust gas energy into kinetic energy without excessive backpressure.
- Integrated Cooling Jackets: For water-cooled models, our housings feature pressure-tested internal galleries to prevent localized hotspots and minimize thermal distortion of the bearing seat.
- Burst Safety Compliance: Reinforced casing walls designed to contain internal component failures, meeting international maritime safety and “containment” regulations.
Professional Supply & Technical Support
- Dimension Verification: We provide detailed drawing confirmations (A-B-C measurements) for all casing orders to ensure 100% fitment with your existing rotor shaft and nozzle ring.
- Component Synchronization: We can supply matching Nozzle Rings, Cover Rings, and Bearing Casing assemblies as a complete “hot-side” kit for major overhauls.
