Bladder Surge Tank
A Bladder Surge Vessel is a surge control device installed with a butyl rubber bladder. A pre-charge pressure is calculated to give the required elasticity to push the water into the system following a pump trip. As there is no contact between the compressed air and the water, there is no dissolution. Thus, there is no requirement for a permanent regulation system including compressors, etc.
Once the vessel has been commissioned and the correct pre-charge has been introduced, the vessel will operate automatically, emptying when called upon and refilling with the return waves until naturally reaching its steady state balance.
The vessels can be installed either horizontally or vertically.
In order to verify the water level in the vessel, it is normally equipped with a level indicator as well as a manometer to verify the initial pre-charge pressure.
Materials and Corrosion Protection
Body material: steel P265GH Gr60 or P295GH Gr70
Coating: The vessels are treated internally with food quality epoxy paint for corrosion protection and externally polyurethane lacquer colour with anti corrosion polyurethane thickness according to client.
Working pressure range: up to 100bar
- Maximum operating temperature: 60°C.
- The Bladder Surge Tank can be used in both potable water and wastewater applications.
