Safety Precautions
When using sight glass discs, it is essential to follow the guidelines outlined in DIN 8902. This includes:
- Replacing glass discs and gaskets after disassembly or removal from service
- Ensuring proper cleaning of recesses and parts before installation/reassembly
- Avoiding over-tightening of retaining bolts
- Not reusing sight glass discs that have been removed from operating use
Planned Maintenance
Regular visual inspections and periodic checks using ultrasound wall thickness measuring means are recommended to ensure the sight glass disc’s service life. In the event of damage, a new glass disc must be promptly exchanged.
Caution: Decriminalised water may dissolve glass, requiring regular inspection to prevent damage.
Breakage Prevention
While rare, breakage can occur due to external influences. To minimise the risk, safety precautions should be taken by plant manufacturers or users to prevent entry of glass particles into critical products.
