Honeycomb Seal
Our Honeycomb Seal replaces traditional teeth with a honeycomb design on the sealing face. Each hole acts as a damping cavity. Steam entering these cavities forms small vortexes that quickly dissipate energy, dramatically reducing leakage. High-temperature alloy honeycomb strips are vacuum-welded to the seal body for precision and durability.

Why Choose Our Honeycomb Seal?
1. Honeycomb Structure Provides Strong Damping
Our Honeycomb Seal replaces traditional teeth with a honeycomb design on the sealing face. Each hole acts as a damping cavity. Steam entering these cavities forms small vortexes that quickly dissipate energy, dramatically reducing leakage. High-temperature alloy honeycomb strips are vacuum-welded to the seal body for precision and durability.
2. Non-Contact Design Protects the Rotor
The seal maintains a radial gap of 0.25 – 1.0 mm, allowing safe operation even if the rotor moves slightly. Unlike traditional hard-contact seals, it does not scratch or damage the shaft. The honeycomb structure also reduces flow-induced vibration, lowering overall unit vibration by 15% – 30%, making it ideal for turbines above 300 MW.
3. Precision Welding for Long Life
Our workshop follows strict environmental and quality standards. Precision vacuum welding ensures the honeycomb strips remain securely attached, preventing failures. The seal can be customized in hole diameter and depth to match specific working conditions. Operating range: -50°C to 700°C, pressure up to 12 MPa, leakage reduction of 40% – 70%, and service life 4 to 8 years.
