	Erosion is normally expressed as a rate of metal loss, usually mm/year. It usually occurs in turns or protrusions; or with solids content.		Erosion is normally expressed as a rate of metal loss, usually mm/year. It usually occurs in turns or protrusions; or with solids content.

 ==Erosional velocity==
-The flow of a gas-liquid multiphase system may cause erosion if velocities are high. This is the description of empirical relationships for estimating whether erosion will occur in a system at a certain velocity used at [[:Category:PQplot|PQplot]].
+[[Erosional velocity]] is a velocity of the multiphase flow at which pipe erosion occurs.
