Custom High-Temperature Pressure Resistant Steam Chamber Cover with Precision Machined Sealing Surface for Steam Turbines
Product Details
The steam chamber cover (inlet steam chamber cover) is a critical pressure-bearing stationary component of steam turbines. It is installed on the steam chamber and bears high temperature, high pressure steam load, thermal alternating stress and pipeline reaction force. It ensures reliable sealing of the main steam inlet chamber, prevents steam leakage, and maintains stable airflow distribution inside the turbine.
We provide fully customized manufacturing services of steam chamber covers for large thermal power turbines, industrial small & medium turbines, waste heat turbines, back-pressure turbines and condensing turbines. Products include integral cast steam chamber covers and split combination covers. We produce strictly in accordance with customer drawings and power industry standards, supporting new unit manufacturing and overhaul replacement. Stellite hardfacing is available for sealing surfaces on request.
- Integral cast steam chamber cover
- Horizontal split steam chamber cover
- Flanged type steam chamber cover
- Optimized retrofitted cover for old unit sealing improvement
ZG15Cr1Mo1V, ZG20CrMo, ZG230-450 and other high-temperature pressure-resistant cast steels. Material selection is determined according to operating temperature, steam pressure and medium parameters.
- Drawing audit & technical parameter confirmation
- Mold making & precision casting
- Stress relief annealing and normalizing & tempering heat treatment
- Rough machining
- Secondary stress relief treatment
- Precision CNC finishing: flange surface, bolt holes, sealing groove, positioning surface
- Optional: Stellite alloy hardfacing on sealing face
- Hydraulic pressure test (as required)
- Strict non-destructive testing: UT, MT, PT for surface & internal defects
- Deburring, anti-rust treatment and export wooden case packaging
Adopt dedicated high-temperature cast steel with standardized heat treatment. Compact casting structure, low internal defect rate, excellent creep resistance and thermal fatigue resistance, suitable for long-term operation under high temperature & high pressure steam conditions.
Precision processing of flange sealing surface and bolt hole array, good flatness and fitting accuracy. Effectively avoid flange steam leakage after assembly.
Custom design and production based on customer drawings: different outline sizes, split structure forms, sealing groove styles and interface standards. We offer targeted optimization schemes for leakage problems of existing units.
We can supply full technical files including casting material reports, heat treatment records, machining inspection data, NDT certificates and hydraulic test reports, complying with power station equipment standards.
Applicable for main steam inlet chambers of high-pressure, medium-pressure stages of various steam turbines. Widely used in power generation, waste heat recovery, chemical, metallurgy and papermaking industrial drive turbines.
- Thermal power generation steam turbines
- Cogeneration heating industrial turbines
- Waste heat recovery steam turbines
- Small & medium condensing / back-pressure turbines
