Erosional velocity
Erosional velocity is a velocity of the multiphase flow at which pipe erosion occurs.
Erosional velocity equation
Pipe erosion begins when velocity exceeds the value of
where:
= gas velocity, ft/s
= empirical constant (starting erosional velocity), lb/s/ft2
= gas density, lb/ft3
API RP 14E (1984) suggested C=100 for continuous and 125 for non continuous service.
Erosion
Erosion is a loss of original material due to solid particle impact on the material surface.
Erosion is normally expressed as a rate of metal loss, usually mm/year. It usually occurs in turns or protrusions; or with solids content.
One can relate Erosional velocity to a metal loss rate (see RP O501).
