Definition - What does Surge Tank mean?
A surge tank refers to a fluid containment device used to neutralize pressure in conveyance and other processing systems. Surge tanks are designed to resist spikes in pressure drop conditions, thereby enabling system stability.
Corrosionpedia explains Surge Tank
The most common types of surge tanks include:
- Simple surge tanks
- Gallery surge tanks
- Inclined surge tanks
- Restricted orifice surge tanks
- Differential surge tanks
These structures are prone to crevice corrosion due to their rigidity and because they usually contain water. They are typically storage reservoirs at the downstream end of a feed pipe designed to absorb and furnish water quickly during a drop in pressure. This enables it to act as a surge chamber.
