Custom High-Temperature Resistant Steam Turbine Valve Sleeves with Precision Honing and Fully Customizable Structure
Detalhes do produto
Valve sleeves are critical sliding matching components located inside steam turbine main stop valves, regulating valves, and intercept valves. These components directly withstand high-temperature steam scouring, thermal deformation, and frequent friction with valve plugs.
We provide comprehensive custom manufacturing services for all specifications of turbine valve sleeves, supporting customization based on customer drawings, samples, and unit operation parameters. Our solutions are compatible with both domestic and imported steam turbine units, ranging from small industrial turbines to large thermal power generating sets.
All valve sleeves are manufactured using high-temperature resistant alloy steel forgings and completed through multi-process CNC turning, precision boring, heat treatment, and inner hole honing. This ensures stable mechanical performance under demanding high-temperature and high-pressure working conditions.
Customize outer diameter, inner bore, length, mounting flange, flow holes, threaded sections, sealing shoulders, and cooling hole layout as required. We support non-standard special structure modifications for old unit retrofits and new turbine R&D projects.
Optional certified raw materials include 12Cr13, 15Cr1Mo1V, F91/F92, P91, 42CrMo, and other turbine-special alloys. All materials come with complete MTC (Material Test Certificate) and feature excellent anti-oxidation, anti-steam erosion, and low creep performance.
- Precision honing for inner sliding bore with surface roughness Ra ≤0.4μm
- Strict dimensional tolerance control to guarantee perfect fit with valve plug
- Optional surface strengthening: nitriding, hard chrome plating, Stellite overlay welding
- Concentricity & straightness fully controlled to prevent valve jamming during operation
Each valve sleeve undergoes comprehensive testing including dimensional inspection, hardness testing, ultrasonic flaw detection (UT), penetrant testing (PT), metallographic analysis, and assembly matching tests. All inspection reports are delivered together with the finished products.
Applicable to high-pressure, medium-pressure, and low-pressure turbine valves, our valve sleeves are widely used in thermal power plants, steel mills, chemical factories, biomass power plants, paper mills, and cogeneration stations.
- Outstanding high-temperature strength and thermal stability
- Ultra-smooth inner bore ensuring flexible valve movement without sticking
- Strong resistance to steam erosion and long service life, reducing maintenance downtime
- Flexible custom solutions for equipment replacement and new project development
- Professional technical support from drawing review to after-sales installation guidance
