Birkosit Dichtungskitt®
Birkosit has been developed in cooperation with Siemens. Approved and used by all major turbine manufacturers worldwide since 1952. Birkosit is the only product that can withstand temperatures in excess of 900 degree Celsius and pressures of 250 bar. Used for sealing steam and gas turbines, compressors, generators, expanders, pumps, flange joints, etc. The adhesion on sealing surfaces and butt joints is so high that a one hundred percent seal is guaranteed even for pressures up to 250 bar. The pressure resistance for flanges without sealing rings is guaranteed up to 450 bar, and even up to 550 bar for screw joints. This ensures sufficient safety factor even for super critical turbines and improves reliability in turbines operating in 170 to 225 bar range.
BIRKOSIT Dichtungskitt® is a single-component, paste luting agent/sealing material for industrial use wherever conditions of temperature combined with pressure on smooth, plane sealing surfaces (butt joints) make extreme demands on the quality of the sealing compound.
Temperature resistance: BIRKOSIT Dichtungskitt” withstands hot steam and air, hot and cold water, light fuel oils and lubricants, as well as crude oil and natural gas at temperatures of up to 900 °C.
Pressure resistance: The adhesion on sealing surfaces and butt joints is so high that a one hundred percent seal is guaranteed even for pressures up to 250 bar. The pressure resistance for flanges without sealing rings is guaranteed up to 450 bar, and even up to 550 bar for screw joints.
Service life: When used in accordance with instructions and with regular servicing as required for steam and gas turbines as well as for the application areas stated above, we guarantee a service life for use on machined sealing surfaces (butt joints) of 10 years.
Application: Apply the BIRKOSIT Dichtungskitt to the dry sealing surfaces with a brush or putty knife on both sides. The layer thickness to be applied is 0.2 mm to 0.3 mm.
The product can be subjected to workloads immediately! It does not cure, will not change its consistency even after several hours, and remains flexible and elastic. It is therefore also suitable for butt joint machining.
The colour is reddish brown.
Heating the tin to room temperature or adding a tenth part of standard linseed oil varnish (AIS B020) from our product range will improve the brush ability.
