Customizable Corrosion Resistant Honeycomb Seal for Energy Saving Steam Turbines
Ürün Ayrıntıları
Steam turbine honeycomb seals are critical energy-saving components installed between turbine rotors and cylinder diaphragms. The dense hexagonal honeycomb structure creates multi-stage labyrinth barriers that limit steam leakage, directly enhancing power generation efficiency and reducing operating costs for thermal power plants.
As a professional manufacturer specializing in custom honeycomb seals for power equipment, we provide tailored sealing solutions for steam turbines, gas turbines, and industrial compressors worldwide.
We customize all product specifications to meet your unique operational requirements:
- Structural customization: Arc radius, honeycomb cell size (0.8mm~6mm), honeycomb strip thickness, seal block dimensions, mounting flange holes
- Material customization: Hastelloy X, Hastelloy C22, 316L stainless steel, Inconel alloy for superior high-temperature and corrosion resistance
- Process customization: Laser seamless welding, integral bending, segmented split design, high-temperature oxidation resistant coating
- Tolerance customization: Strict dimensional control to match turbine rotor clearance requirements and prevent rubbing failure
The hexagonal honeycomb labyrinth structure effectively traps steam flow and suppresses vortex leakage. Compared to traditional tooth-type seals, it reduces internal steam leakage by 30%~60%, significantly improving unit output and reducing coal consumption per kWh.
The soft honeycomb structure wears slightly during accidental rotor-stator contact without damaging turbine rotors. This prevents costly rotor scratch damage and extends power unit overhaul cycles.
Alloy base materials with high-temperature anti-oxidation treatment resist erosion from high-temperature steam, steam oxide, and flue gas impurities. Ensures stable sealing performance for long-term continuous operation with reduced replacement frequency.
Precision CNC bending and laser welding ensure consistent arc flatness and dimensional accuracy. No deformation during installation, tight fit with turbine cylinder and diaphragm, eliminating the need for secondary on-site processing.
- Raw material inspection: Alloy composition spectrum analysis, high-temperature resistance testing
- Semi-finished inspection: Honeycomb cell uniformity, welding tensile strength testing
- Finished product inspection: 3-coordinate dimensional measurement, flatness & curvature detection, penetration flaw detection for welding seams
- Simulation testing: Matching tests with customer turbine casing samples
All products include comprehensive inspection documentation to support factory audits and export quality traceability.
