Mica Shields

Mica Manufacturing Co Pvt Ltd offers Mica Shields that provide the best protection possible to flat transparent, sight glasses in water and liquid level gauges and columns in high pressure steam boilers. The shields retain basic strength and increase the service life of sight glasses when used at increased steam pressures and high working temperatures. Mica shields also provide perfect visibility for monitoring the nature or degree of combustion in blast furnaces of steam boilers. Natural mica has extremely high heat resistance, transparency, optical clarity, flexibility, flatness and is unbreakable. The transparency of mica is not affected by the repeated fluctuations in heating and cooling and is not attacked by most of the gases and vapours it might come into contact with. In addition, mica resists shocks, strains and vibrations and therefore can easily be used in place of glass where there is a likely hood of exposure to radiant heat, breakage or cracking. As steam boilers are frequently shut-down and started up again, this places extreme demands on the transparent glasses fitted between CAF sealing gaskets and cushion joints of the level gauges. It is therefore essential to protect these glasses with mica shields by fitting them on the side facing the medium chamber. MICA shields are a must where saturated steam pressure exceeds 350 psi (up to 5689 psi) and working temperatures exceed 196°C (up to 600°C).
