Product Description
Customized Steam Turbine Middle Cylinder
The middle cylinder is a core pressure-containing casing of steam turbines, located between the front (high-pressure) cylinder and the exhaust (low-pressure) cylinder. It houses the intermediate-pressure rotor and inner casing assembly, bearing combined loads of intermediate-temperature & intermediate-pressure steam, cyclic thermal stress, mechanical force and bolt preload during turbine operation. It plays a decisive role in steam flow distribution, thermal efficiency and unit operational safety.
We deliver fully-customized middle cylinder solutions according to customer drawings, unit rated parameters and on-site working conditions. Our products are widely applied in new power-plant construction, turbine retrofitting, technical upgrade and overhaul spare-part supply for thermal power, combined heat-and-power, industrial waste-heat power, chemical self-owned power stations and biomass power plants.
Material & Manufacturing Process
Qualified high-strength cast steel complying with turbine industry standards is selected for casting. The complete manufacturing procedure includes mold making, casting, stress-relieving heat treatment, rough machining, multi-procedure non-destructive testing (UT, MT), precision CNC finishing, horizontal joint flange processing, steam-seal groove machining and assembly dimensional verification. Strict process control eliminates casting porosity, inclusions and residual stress to guarantee intrinsic material quality.
Core Product Advantages
High Structural Rigidity & Anti-deformation Performance
Optimized wall-thickness and reinforcing-rib layout effectively resist distortion under frequent start-stop and load-changing conditions, maintaining stable dimensional accuracy under long-term intermediate-temperature service.
Dependable Flange Sealing Property
High-precision machining for horizontal split flange, bolt hole array and mating surfaces reduces steam leakage between cylinder halves, improving overall unit heat efficiency.
Superior Thermal Compatibility
Well-optimized structural layout for uniform thermal expansion lowers thermal stress risk during unit startup, shutdown and load swing, mitigating cracking risks and extending component service life.
Full-range Customization Capacity
Customizable outer dimensions, flange configurations, steam inlet & outlet nozzle positions, bolt specifications and inner-cavity profiles. Services cover drawing-based OEM production and reverse manufacturing.
Rigorous Quality Assurance
Every finished middle cylinder undergoes full-set acceptance inspections: dimensional tolerance measurement, surface inspection, multi-item NDT non-destructive examination and material certification validation. Complete traceable production records will be provided for client acceptance.
Application Coverage
Suitable for multiple-capacity steam turbine units in thermal power plants, cogeneration plants, metallurgical waste-heat power stations, chemical enterprise captive power plants, biomass power generation and other energy facilities.
We provide one-stop services including technical consultation, structural optimization suggestion, production, factory acceptance and after-sales technical support. Please feel free to send us your drawings or unit technical parameters for quotation and customized solution discussion.
