Mica shields
Mica shields provides 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. Sight glasses in steam boilers are exposed to harsh operating conditions (thermal, mechanical and chemical). On the surface of the glass crystallized deposits of mineral substances interact aggressively on the surface of the glass, especially at higher temperatures and pressures, and depending on the pH of the liquid. This interaction not only leads to tarnishing glass, but also the erosion, manifested by decreasing the thickness of the sight glass, which reduces its strength and may lead to dangerous failure. Glass losses for unprotected sight and gauge glasses, depends mainly on the pH and the temperature of the boiler water, could reach millimeters per month (see. fig. below).
