Custom Honeycomb Seals for Steam Turbines
Product Overview
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.
Comprehensive Customization Solutions
We customize all product specifications to meet your unique operational requirements:
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
Outstanding Product Performance
Remarkable Energy Saving & Leakage Reduction
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.
Excellent Rub Tolerance & Safety
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.
Long Service Life Under Severe Conditions
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.
Perfect Assembly Matching
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.
Complete Quality Control System
Raw material inspection: Alloy composition spectrum analysis, high-temperature resistance testing
