Product Description
Customized Steam Turbine High-Pressure Outer Cylinder
The high-pressure outer cylinder is the outermost major pressure-containing casing of the steam turbine high-pressure module. It encloses the high-pressure inner cylinder, diaphragm assemblies and rotor stages. During unit operation, it bears severe combined loads of ultra-high-temperature and high-pressure steam, thermal expansion stress, mechanical load and heavy bolt pre-tightening force. Its material performance, structural stiffness and flange sealing directly determine the safety, heat efficiency and service life of the high-pressure turbine section.
We deliver fully-customized high-pressure outer cylinder solutions according to client-supplied drawings, unit technical specifications and real-site operating conditions. Our products are widely used for new-build power projects, turbine modification & upgrading, and overhaul spare-part supply in 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-temperature creep-resistant turbine-grade cast steel is selected for casting. The complete production workflow includes pattern making, casting, stress-relieving heat treatment, rough machining, multi-procedure non-destructive testing (UT, MT), high-precision CNC finishing, horizontal split flange processing, nozzle connection seat machining and assembly-fit dimensional verification. Strict process control eliminates casting defects such as porosity and inclusions and relieves internal residual stress to ensure stable material performance under harsh high-temperature working conditions.
Key Product Advantages
- ✓Superior High-Temperature Structural Rigidity & Creep Resistance - Optimized wall-thickness and reinforcing-rib layout. Resists thermal deformation and high-temperature creep under long-term ultra-high-temperature service; maintains stable dimensional accuracy during frequent startup-shutdown and load-fluctuation cycles.
- ✓Dependable High-Temperature Flange Sealing Performance - Precision-machined horizontal joint flange, bolt hole array and mating surfaces. Effectively reduces high-temperature steam leakage across split joints, lowers energy loss and improves overall unit thermal efficiency.
- ✓Excellent Thermal Stress Adaptability - Well-balanced structural design ensures uniform thermal expansion. Mitigates thermal-stress concentration risks during unit start-up, shutdown and load swing, preventing cracking and extending component service life.
- ✓Full-range Customization Capability - Customizable overall dimensions, flange layout, steam inlet/outlet nozzle positions, bolt specifications, inner cavity profile and mounting interfaces. Services cover drawing-driven OEM production as well as reverse-engineering customization based on original unit parameters.
Rigorous Quality Assurance
Each finished high-pressure outer cylinder goes through complete acceptance inspections: dimensional tolerance measurement, surface quality examination, multi-item NDT non-destructive testing and material certification validation. Full traceable production documents are provided for customer acceptance.
Application Scenarios
Suitable for various-capacity steam turbine units in thermal power plants, cogeneration plants, combined heat-and-power plants, industrial waste-heat power stations, chemical captive power plants and biomass power facilities.
