BIRKOSIT 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. It 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.
It is the only turbine parting plane flange sealant developed in cooperation with a turbine maker, Siemens. Used today by Nuclear Power, NTPC, Siemens, BHEL, L&T Mitsubishi, Triveni and all other OEMs, this highest temperature and pressure resistance sealing product is used for sealing the steam and gas turbine flanges in all power stations.
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.
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.
Fields of Application
It is suitable for sealing all surface sizes.
Packed in 1 kg tins. If stored correctly, BIRKOSIT has a storage life of 5 years in the tin. Its properties are stable and it is flexible in use. Close the tin properly if only a part of the contents is going to be used.
