SIGHT GLASS is a transparent window used to observe the flow of fluid inside a pipe, container or equipment. It is widely used in industries such as chemical, pharmaceutical, food processing, water treatment and heating, ventilation and air conditioning (HVAC). The following are some typical features and functions of sight glasses:
Visual monitoring: Sight glasses allow operators to directly observe the flow of internal fluids, including flow, color, impurities and bubbles.
Material selection: Sight glasses are usually made of transparent materials such as glass, acrylic (acrylic) or polycarbonate to ensure corrosion resistance and temperature resistance.
Pressure-resistant design: Sight glasses are designed to withstand internal pressure and are suitable for high-pressure systems.
Easy to install: Sight glasses are usually designed to be easily installed on pipes or equipment, which can be threaded, flanged or welded.
Easy maintenance: Sight glasses are designed to be easy to clean and replace to maintain clarity of observation.
Safety features: Sight glasses may have explosion-proof designs and are suitable for flammable and explosive environments.
Multiple sizes and shapes: Sight glasses are available in a variety of sizes and shapes to accommodate different pipe diameters and observation angles.
Anti-fog function: In environments with high temperatures or large temperature differences, the sight glass may have an anti-fog function to keep the field of vision clear.
Based on the pictures you provided, these sight glasses may have the following features:
Made of brass or copper: The sight glass body may be made of brass or copper, which has good corrosion resistance and wear resistance.
Transparent window: The sight glass has a transparent window that allows the operator to observe the internal fluid.
Dry indication: Some sight glasses may have a dry indication function to show whether the system is in a dry state.
Multiple sizes: The pictures show different sizes of sight glasses, suitable for pipes of different diameters.
