Manufactured in 3.3 Borosilicate Glass, these level gauge glass tubes are used in applications where a visual inspection of the level in needed, as well as good chemical resistance and low thermal expansion coefficient.
Sight glasses for steam boilers are categorized into three main wall thickness types: standard wall, high-pressure wall, and heavy wall (the thickest). Each type is engineered to withstand varying pressure levels, ensuring the sight glass operates safely under the boiler's operating conditions.
The pressure resistance of a sight glass depends on its wall thickness. As the internal pressure in a boiler rises, the glass must endure the force applied to its walls. Thicker walls offer greater resistance to this pressure, thereby decreasing the risk of breakage. For instance:
These type of tubes are used for direct indication of the level in a recipient. These are used with Level Gauge Valves and washers, which can be purchased in our website as well.
Creates an optical effect where the red line among two white lines is magnified, allowing distant observation of the fluid.
