Harwood’s rupture tube safety assemblies are used to release excessive pressure in case of an emergency, if the system’s relief or pressure release valves have failed. The burst pressure should be about 10-15% higher than the maximum pressure of the system. And the tolerance of the burst pressure is ±5%.
Our industrial rupture tube safety assemblies are manufactured and tested in-house. We perform thorough inspections and burst testing to ensure proper performance with each new batch of assemblies.
Safety Assemblies Features:
- Service for liquids and gases
- Time-proven designs – in use for over 60 year.
Safety Assemblies Options:
- Stainless steel assemblies for water and hydrogen service
- Custom burst pressures available
