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.
