Birkosit Turbine Sealing Compound Sets New Standards

Operational Safety in Power Stations

With a view towards the greatest possible operational safety, particularly high standards have to bemet by the materials used in power stations. These also include sealing compounds, particularly thosefor sealing turbine parting planes. In the presence of water or steam, halogens such as chlorine andfluorine can corrode the surface structure, causing cracks to form.

Recently Thermax India asked a sealant manufacturer AI Schulze to confirm that Birkosit contains nosulphur or halogen materials (chlorine, fluorine, bromine, etc) that could potentially cause corrosion onmetal surfaces. AI Schulze, the manufacturer issued the certificate to Thermax. This is now standardfor all supplies for Birkosit. Birkosit now certifies that it contains no chemical substances (it is based onlinseed oils instead of flammable solvents) nor contains any hazardous substance.

With the new generation turbines being manufactured by BHEL, L&T Mitsubishi, Siemens and others, itis now imperative that sealing compounds designed for turbines have to meet several key parameters:
