Industrial Round Tempered Sight Glass Disc

一、 Product Introduction

The circular glass piece in the picture is sodium calcium tempered mirror glass, with a light green color on the side, which is a material characteristic of ordinary float glass itself. The overall shape of the product is flat and circular, with finely ground and chamfered edges that are smooth and free of burrs. It is not easy to break or scratch the sealing gasket during installation and is suitable for flange installation structures of various equipment.

High quality float glass is selected as the raw material and processed through high-temperature tempering technology. Unlike ordinary white glass, it has stronger physical protection performance and is a cost-effective industrial observation accessory under normal temperature and low pressure conditions.


二、 Core performance advantages


Explosion proof and pressure resistant, high safety factor

After tempering treatment, the impact resistance and compressive strength of glass are several times that of ordinary glass. Even if it is broken by external force, it will shatter into small particles without sharp edges, and will not produce sharp fragments to scratch personnel, meeting the safety standards for the use of pressure vessels and storage tank equipment.


High transparency, clear observation

The light transmittance can reach over 90%, and through the glass, the internal liquid level, material reaction, and medium flow state of the equipment can be clearly observed without blurring or fog obstruction, making it easy for staff to grasp the real-time operation of the equipment.


Acid and alkali resistance, water vapor corrosion resistance

Capable of withstanding daily water vapor, oil, and weak acidic and alkaline media erosion, long-term use is not prone to whitening, corrosion, and fogging, suitable for various humid and slightly corrosive production environments such as water treatment, food processing, general chemical,  etc.


Flexible specifications and convenient processing

Different diameters and thicknesses can be customized as needed, with common thicknesses of 3mm, 5mm, 8mm, 10mm, 15mm, etc. Both sizes can be cut and polished, supporting large-scale standardized production and stable delivery time.


三、 Mainstream application scenarios


Storage tanks and reaction equipment

Various room temperature mixing tanks, storage tanks, fermentation tanks, and small reaction vessels have manhole observation windows to visually view the internal material mixing and fermentation status;
