Honeycomb Seal

Honeycomb gas seals are mainly used in turbine machinery such as aviation engines, gas turbines, and steam turbines, as well as chemical equipment. Seals are mainly divided into blade top seals, baffle (or stationary blade ring) seals, and shaft seals based on their position and function.


Honeycomb sealing can produce good sealing effect, reduce airflow loss, and improve aerodynamic efficiency. The honeycomb seal at the top of the blade also has a good dehumidification effect, which can effectively protect the blades from erosion by water vapor. Materials and dimensions can be customized according to customer requirements, while providing consulting services on product design and application.
