一 、 Core definition: What is 304Tempered Glass Sight Glass ?
304 tempered glass sight glass is an observation window component widely used in industrial pipelines, tanks, boilers, and pressure vessels. Its core function is to allow operators to visually observe the flow status, color, liquid level, presence of bubbles or impurities of the internal medium without interrupting the process or opening the equipment.
It is not a single glass component, but a precision assembly composed of high-strength tempered glass and 304 stainless steel metal components.
二 、 Main features and advantages
1，Safe and reliable:
High strength: The impact and bending strength of tempered glass is 3-5 times that of ordinary glass.
Safety design: In case of breakage due to extreme circumstances, tempered glass will shatter into small particles without sharp angles, greatly reducing the risk of harm to the human body.
2. Excellent weather resistance:
Corrosion resistance: The 304 stainless steel shell can adapt to various complex industrial environments and has a long service life.
High and low temperature resistance: The mirror component can withstand a wide range of operating temperatures from low to high.
3. Excellent sealing performance:
Through precise mechanical processing and appropriate gaskets, long-term and stable sealing can be achieved to prevent medium leakage.
4. Clear and intuitive observation:
High transmittance glass provides a clear view and is the most direct and effective means of monitoring the process flow.
5. Easy maintenance:
When glass needs to be replaced or cleaned, the structural design usually allows for disassembly and assembly from the outside of the equipment without cutting pipes, making maintenance convenient.
三 、 Main application areas
Petrochemical industry: Observing the flow state of oil, chemicals, and gases in pipelines.
Food and pharmaceuticals: Monitor the flow and cleanliness of fluid food, beverages, pharmaceuticals, and dairy products in sanitary grade pipelines.
Electric power industry: used for water level gauges and flame observation glasses in boilers.
Water treatment and environmental protection: monitoring the water flow of filtration equipment and dosing systems.
Industries such as papermaking and metallurgy: any industrial process that requires visual process control.
四 、 Selection and Precautions
When choosing and using 304 tempered glass mirrors, it is important to pay attention to the following points:
Working pressure (PMA) and working temperature (TMA): It is necessary to ensure that the rated parameters of the sight glass are higher than the actual operating conditions of the equipment.
Medium compatibility: Confirm that the 304 stainless steel material and sealing gasket material can resist corrosion from the medium they come into contact with.
Caliber and connection method: Select the appropriate diameter and connection form based on the pipeline size and standards (such as flange standards HG/T, GB, etc.).
Regular inspection: It is necessary to regularly check the glass surface for scratches, cracks, and whether the sealing surface is intact to ensure its continuous and safe operation.
