The front cylinder (high-pressure casing) serves as one of the most critical pressure-containing components of steam turbine equipment. It encloses the high-pressure stage rotor and inner casing, sustaining complex loads from high-temperature & high-pressure steam, thermal expansion, mechanical stress and bolt pre-tightening force during unit operation.
We provide fully customized front cylinder solutions tailored to customer-supplied drawings, unit parameters and actual site operating conditions, applicable for new power-plant projects, unit retrofitting, and overhaul spare-part replacement across thermal power, cogeneration, industrial waste-heat power generation fields.
Complete production workflow: casting, stress-relieving heat treatment, rough machining
Comprehensive non-destructive testing: ultrasonic & magnetic particle inspection
Precision fine CNC machining and sealing-surface finishing
Assembly fit inspection and strict quality control standards
Elimination of casting defects and residual stress
Key Performance Advantages
Superior Structural Rigidity
Optimized wall-thickness and rib-reinforcement structure, resisting deformation under drastic temperature-change cycles, maintaining stable dimensional accuracy under long-time high-temperature service.
Reliable Sealing Performance
Precision-processed horizontal joint flange, bolt hole distribution and steam-seal groove surfaces. Minimize steam leakage, improve unit thermal efficiency.
Excellent Thermal Adaptability
Reasonable structure design for uniform thermal expansion, reduces thermal stress risk during unit start-up, shutdown and load fluctuation, extending service life.
Full Customization Capability
Customizable casing dimension, flange layout, steam-inlet/outlet port position, bolt specifications, inner-cavity profile. Accept both reverse manufacturing and drawing-based OEM production.
Strict Quality Assurance
Each finished front cylinder undergoes complete inspections including:
Dimensional tolerance check
Surface quality examination
Multi-item NDT non-destructive testing
Material certificate verification
Full traceable production documentation
Application Scenarios
Suitable for various-capacity steam turbines across multiple industries:
Thermal power plants
Combined heat & power plants
Steel mill waste-heat power generation
Chemical industrial self-owned power stations
Biomass power generation
Other energy-generation facilities
We deliver comprehensive one-stop service including technical communication, design optimization, production, inspection and after-sales technical support. Contact us with your technical drawings or unit parameters for quotation and customized solution consultation.
