Tempered borosilicate circular view glass (also commonly referred to as industrial view glass) is a specialized type of glass specifically designed for industrial equipment and serves as a critical safety component in industries such as chemicals, power, and food.
一，Material and Performance
It is made of borosilicate glass as raw material and undergoes tempering treatment, with a strength 2-3 times higher than ordinary glass and an impact resistance improvement of 5-10 times.
High temperature resistance: Long term temperature resistance can reach 200-300 ℃, and some high specification products can withstand higher temperatures for a short period of time.
High pressure resistance: Depending on the thickness, it can withstand industrial pressures of 0.6-16MPa.
Acid and alkali resistance: except for hydrofluoric acid and hot phosphoric acid, it can withstand most acid-base corrosion and is suitable for chemical media scenarios.
High transparency: With a transparency rate of ≥ 90%, the internal working conditions of the equipment can be clearly observed.
二，core purpose
It is installed on equipment such as reaction vessels, boilers, pipelines, pressure vessels, etc. as an observation window, allowing operators to monitor the internal medium flow and reaction status in real time, while ensuring the sealing and safety of the equipment.
Common scenarios: chemical reaction kettle sight glass, boiler water level observation window, food and pharmaceutical equipment sight glass, pipeline flow observation port, etc.
三 ，Specifications and Customization
This type of glass supports customization, with diameters ranging from tens of millimeters to hundreds of millimeters, and thickness can also be adjusted according to pressure requirements to adapt to installation standards of different devices (such as DIN, national standards, etc.).
