Solar Energy CSP

Concentrated Solar Power (CSP) plants utilize long glass tubes in which a fluid (mostly oil) is heated by arrays of parabolic mirrors, up to a mile long.

The individual glass tubes must be connected and shielded with special metal rings that will endure heat, temperature variation and stress, all under vacuum conditions and must show a longlife connection to the glass under these circumstances.

KeyTec was able to identify appropriate metal with identical thermal expansion coefficient as the used glass, to set up a mass production process to manufacture these components and to develop a coating process that guarantees a stress free and long life connection.
