Mica shields are used with transparent gauge glass to protect the glass from chemical attack and to provide a higher working pressure for the gauge. The nature of the Mica ensures that there is no visual obstruction through the gauge glass to the water level, even as the temperature of the media increases. The natural structure of the Mica allows for the shields to be strong, flat, flexible, resitant to chemical abbrasions and unbreakable.

Common issues faced with gauge glass on boilers inlcude crystallised deposits forming on the surface of the glass from mineral substances in the boiler water, which can aggressively interact with the surface of the glass. Other factors that can impact the longevity of the lifecycle of the glass is the pH and temperature of the boiler water, erosion and tarnishing of the glass which can lead to reduced thicknesses of glass and ultimately the increased likelyhood of failure of the glass due to mechanical failure (loss of strength).

By using Mica shields with the transparent glass, the service life of the glass can be increased. These Mica shields are to suit a type B transparent glass with a width of 34mm.

These products are intended for use in industrial applications only. Do not use these products where pressures and temperatures can exceed those listed under ‘Technical Data’ and in our individual ‘Series’ data sheets. Before using these products with fluids other than these specified, for non-industrial applications, life-support systems, or other applications not within published specifications, consult Hawleys Through misuse, age, or malfunction, components used in industrial valve applications can fail in various modes. The system designer is warned to consider the failure modes of all component parts used in industrial valve applications and to provide adequate safeguards to prevent personal injury or damage to equipment in the event of such failure. System designers must provide a warning to the user in the system instructional manual if protection against a failure mode cannot be adequately provided. System designers and end users are cautioned to review specific warnings or specifications found in instruction sheets or labels packed or attached and shipped with the products. Our policy is one of continuous research and development. We therefore reserve the right to amend without notice the specifications given in this document or our individual ‘Series’ data sheets.
