Pyrex round glass is known for its high thermal resistance, chemical durability, and optical clarity. When it comes to peep hole glass used in industrial applications, especially in high-temperature environments like furnaces or reactors, certain specifications are crucial for ensuring top quality. Here are some key specifications for high-quality borosilicate peep hole glass:
Material Composition:
Pyrex round glass should comply with international standards like DIN ISO 3585 or ASTM E438 Type I, Class A. These standards ensure the appropriate composition of borosilicate glass, including the required levels of silica and boron oxide.
Thermal Resistance:
Pyrex round glass is chosen for its excellent thermal shock resistance. The peep hole glass should be able to withstand rapid temperature changes without cracking or breaking. A high-quality borosilicate peep hole glass may have a maximum thermal resistance of up to 500°C or more.
Chemical Durability:
Pyrex round glass is chemically resistant, which is particularly important for applications involving exposure to corrosive materials or harsh environments. It should resist attack from acids, bases, and other chemicals.
Clarity and Visibility:
The glass should offer high optical clarity to ensure clear visibility through the peep hole. This is crucial for monitoring processes inside industrial equipment.
Dimensional Stability:
Pyrex round glass should maintain its dimensions and shape under different temperature conditions to ensure a proper fit within the equipment.
Thickness and Size:
The thickness of the glass should be appropriate for the intended application, providing the necessary strength and insulation. The size of the peep hole should also meet the specifications of the equipment it is installed in.
Surface Finish:
A smooth and even surface finish is essential for clear visibility and to prevent distortion of the view through the peep hole.
Resistance to UV Radiation:
In some applications, resistance to ultraviolet (UV) radiation may be important to prevent degradation of the glass over time.
Compliance with Industry Standards:
Ensure that the borosilicate peep hole glass complies with relevant industry standards and certifications to guarantee its quality and performance.
Packaging and Handling:
Proper packaging and handling instructions should be provided to prevent damage during transportation and installation.
It's important to consult with the manufacturer or supplier to get specific details about the borosilicate peep hole glass and to ensure that it meets the requirements of your particular application.
