Application Method of "METSOL" Coating on Turbines. |
|
Benefits of METSOL Coating in Hydro Electric Turbines |
METSOL makes monolithic joint with metal surface and provide frictionless movement to the suspended hard foreign particles of inlet water. It helps to prevent metallic erosion and corrosion of turbine surface.
- It reduces and prevent erosion and corrosion of MS parts.
- It protects turbine body deterioration and maintain its mechanical strength.
- It provides zero friction to the moving suspended hard particles in inlet water, so minimum coating erosion .No direct contact with metal parts.
- It is non metallic and chemically neutral, therefore no chemical reactions with coated surface.
- It doesn’t absorb water and it is wettable(non sticky surface).
- It provides electrical resistance to the splitted and polarized colloidal water solution formed.positve and negative acidic molecules does not have any effect, therefore it helps to reduce cation effect and helps to stop/reduce metal disintegration and weakening of MS parts. It helps to reduce suspended metal particles in outlet water.
- It provides lubrication and helps to form emulsified water solution, which is soft in nature without metallic residues.
- It helps to increase the life of metal parts of hydraulic turbine.
- It helps to reduce maintenance cost and breakdown.
- It reduces downtime and turbine will be available for efficient operation, that is it increases operational efficiency of turbine.
- Reduces running cost of turbine.
