4. Configuration
The

standard bladder accumulators are configured as a forged carbon steel pressure
vessels and with NBR-bladder. Other materials are available on request.
The used materials are to be matched to the respective medium and the application data.
5. Safety notes
The current commissioning rules and regulations for a safe operation of hydraulic accumulators
require the observance of all safety-related measures, e.g.:
- appropriate safeguards against excessive pressure
- safety regulations when handling with nitrogen as a filling gas
- use proper and calibrated pressure gauge
- correct connection of the gauge
- shut-off and relief devices, etc.
The operator must ensure that all relevant regulations are observed.
HENNLICH
accessories
for example safety and shut-off blocks include the legal requirements (e.g. acc. to TRB 403) in
