Turbine Sealant : 10 years service life for steam and gas turbines

Nov. 2, 2010 - PRLog -- Used by BHEL, NTPC, NPCIL, Siemens, Tata Power, Lanco, Essar, Torrent, APGENCO, OPGC, Bhushan, etc

Service life of 10 years !  Used for high temperature, high pressure joints ! A Siemens co-operation product developed in 1952 for turbines.

Application area, metal-to-metal joints in steam and gas turbines

BIRKOSIT - Dichtungskitt ®

BIRKOSIT - Dichtungskitt ® Sealing Compound has been used for 50 years on turbines (product development 1952 with Siemens). Without the additional sealing of individual pressure areas using BIRKOSIT - Dichtungskitt ® the production imprecision or the distortion under loads are no longer evened out, which means that the turbine areas in the individual pressure areas become permeable under pressure. This means the turbine loses power, and can even lead to unplanned reconditioning.

BIRKOSIT - Dichtungskitt ® is formulated to be practically inert in its standard applications in steam and gas turbines. It is, therefore, resistant to exposure to hot air, steam, water, light fuel oils and lubricants. By implication, it should be resistant to crude oil and natural gas.

[main application]
single-component, paste sealing compound for sealing between machined surfaces (joints between parts) in steam and gas turbines at temperatures up to 900 °C and pressures up to 250 bar.
[other applications]
can also be used for sealing between smooth surfaces in compressors, housings, pumps etc. and by extension, in valve glands and screw joints.

[additional applications]
All kinds of screwed metal flange pipe connections (independent of flange diameter and shape). Their operating conditions are characterized by water, steam, pressure, high temperature

Service life
When used in accordance with instructions and with regular servicing as required for steam and gas turbines, we guarantee a service life for use on machined sealing surfaces (butt joints), of 10 years.
For high-pressure (H) turbines, we guarantee that the product will withstand hot steam, hot air, hot and cold water, light fuel oils, lubricants, mineral oil and natural gas at temperatures up to 900 °C and pressures up to 250 bar.
Pressure resistance
The excellent adhesion on sealing surfaces and butt joints guarantees a perfect seal up to 250 bar. The pressure resistance for flanges without sealing rings is up to 450 bar; and even up to 550 bar for screw joints

Application Summary at Siemens AG Power Generation Mülheim location
