Product Description
Customized Steam Turbine Front-Middle Combined Cylinder
The front-middle combined cylinder is an integrated pressure-bearing casing that combines the high-pressure front cylinder and intermediate-pressure middle cylinder into one single casting. It accommodates both high-pressure and intermediate-pressure rotor stages and inner casings.
During unit operation, it endures compound loads including high-temperature & high-pressure steam, intermediate-temperature steam, cyclic thermal stress, mechanical loads and bolt pre-tightening force. This integrated structure reduces connecting flanges, cuts steam leakage points and improves overall unit thermal efficiency, widely adopted in modern large- and medium-sized steam turbines.
Custom Manufacturing Solutions
We provide fully customized front-middle combined cylinder solutions based on client-supplied drawings, unit model parameters and actual site working conditions. Our products serve:
- New-build power projects
- Turbine technical retrofitting
- Capacity upgrading
- Overhaul spare-part supply
Applications include thermal power plants, combined heat-and-power plants, industrial waste-heat power stations, chemical captive power plants and biomass power facilities.
Material & Manufacturing Technology
High-strength turbine-grade cast steel is selected for raw casting. The comprehensive production workflow includes:
- Pattern making and casting
- Stress-relieving heat treatment
- Rough machining
- Multi-procedure non-destructive testing (UT, MT)
- High-precision CNC finishing
- Horizontal split flange machining
- Steam-seal groove & nozzle seat processing
- Assembly-fit dimensional verification
Strict process control eliminates casting defects such as porosity and inclusions and relieves residual stress to guarantee intrinsic material performance.
Key Product Advantages
Integrated High-rigidity Structure
The combined casting design removes intermediate connecting flanges. Optimized wall thickness and reinforcing ribs enhance overall structural stiffness, effectively resisting deformation under frequent startup-shutdown and load fluctuation conditions.
Reduced Steam Leakage, Higher Efficiency
Fewer flange joint surfaces lower potential steam-leakage positions. Precisely-processed horizontal split flange, bolt holes and mating surfaces deliver outstanding sealing performance, cutting energy loss and improving turbine cycle efficiency.
Optimized Thermal Adaptability
Well-balanced structural layout realizes uniform thermal expansion for both high-pressure and intermediate-pressure zones. It mitigates thermal stress risks during unit startup, shutdown and load swing, reducing cracking risk and extending component service life.
Full-scope Customization Capability
Customizable overall dimensions, flange layout, steam inlet/outlet nozzle positions, bolt specifications, inner-cavity profile and connection interfaces. We accept drawing-driven OEM production and reverse custom manufacturing.
Strict Quality Control & Assurance
Each finished front-middle combined cylinder undergoes complete acceptance procedures:
- Dimensional tolerance inspection
- Surface quality check
- Multi-item NDT non-destructive examination
- Material certificate verification
Full traceable production documents are provided for customer acceptance.
Application Scenarios
Applicable for various capacity steam turbine units for:
- Thermal power generation
- Cogeneration
- Metallurgical waste-heat power generation
- Chemical self-owned power plants
- Biomass power generation
- Other energy-generation projects
We deliver one-stop services covering technical communication, structural optimization suggestion, production, factory acceptance test and after-sales technical support.
