Honeycomb seals are key components in 21st century machines


Products

Honeycomb strip
Honeycomb strip is used in all types of gas and steam turbines. Primary seal in high- and low-pressure turbines.
Honeycomb shrouds
Profiled honeycomb block prepared for mounting on segments and nozzle blocks of gas turbine engines.
Screening lattices
To protect equipment from electromagnetic radiation.
Structural welded honeycomb
It is used as a core filler for honeycomb panels, including sound-absorbing panels.
Sealing rings for gas turbine engines
Sealing rings for gas turbine engines allow reduction in clearances, and gas interflows, and they increase turbine fuel efficiency.
Structural honeycomb panels
Lightweight structural elements of multiple types and purpose.
Compressor bushings
Compressor bushings allow reduction in clearances, and gas interflows, and they increase the efficiency of the turbo-compressor.
Adhesive-bonded honeycomb
It is used as a filler for panels of multiple types and purpose.
Shrouds for ground gas turbines
They are used in high-power industrial gas turbines allowing reduction in clearances, and gas interflows, and they increase turbine fuel efficiency.
Gland sealing system for steam turbines
It is used in high-power industrial steam turbines allowing reduction in clearances, and gas interflows, and it increases turbine fuel efficiency

What Modern Jet Aircraft, Energy Turbines and Gas Pumping Stations Have in Common?

Honeycomb seals are used everywhere. Today, it is impossible to imagine any modern gas turbine engine or power turbine without these elements. Honeycomb seals are key components of 21st-century machinery. They are based on the honeycomb structure, which allows the working fluid overflow in the radial clearances to be minimized, the relative efficiency to be increased, fuel consumption to be reduced by 5% and abrasive wear of the turbine flow section to be reduced as well.

Welded honeycomb seals are an integral design element of existing aircraft engines and those under development (turbofan, turboshaft engines and auxiliary power units), gas and steam turbines used in the power and oil/gas industries, as well as turbo-compressors. Until recently, only imported high-quality honeycomb seals were available in Russia.

Why Rotek

Wide range of cell sizes of honeycomb materials
for all existing and future aircraft engines, steam and gas turbines
Stability of shape and geometric dimensions
is ensured by the production technology and does not depend on the human factor: the range of cell sizes is 0.9–4.5 mm, wall thickness is from 0.05 to 0.2 mm.
High product quality and precision dimensional accuracy
Production process based on equipment of self-engineered design
Short installation time
Honeycomb strip made pre-soldered or pre-assembled on the plate.
The use of welded honeycomb seals increases the technological performance of turbines and reduces their production costs.

ROTEС production is also equipped with a field tests stand.
