Lumistar supplies DIN 7080 borosilicate sight glass discs with customized sizes and thicknesses for global industrial customers.
Key Features of DIN 7080 Sight Glass:
- Borosilicate glass 3.3 material
- Excellent thermal shock resistance
- High transparency for process observation
- Suitable for pressure vessels and industrial equipment
- Customized diameter and thickness available
What Is DIN 7080 Sight Glass?
DIN 7080 is a German industrial standard for circular sight glass discs mainly used in pressure vessels and industrial sight glass assemblies.
The glass disc is installed between metal retaining rings or flange assemblies, allowing operators to observe internal conditions such as liquid level, flow status, color changes and reaction processes.
Compared with ordinary glass materials, DIN 7080 borosilicate glass features low thermal expansion and excellent resistance to temperature changes, making it suitable for demanding industrial environments.
DIN 7080 Sight Glass Material Properties
The standard material for DIN 7080 sight glass is borosilicate glass 3.3.
This material is widely selected because of its excellent mechanical, thermal and chemical performance.
| Property | Performance |
|---|---|
| Material | Borosilicate Glass 3.3 |
| Thermal Expansion | Low expansion coefficient with excellent thermal shock resistance |
| Temperature Resistance | Suitable for high temperature industrial applications |
| Chemical Resistance | Excellent resistance to many chemicals |
