Case I:

Erosion in Pipeline Branch of line Medium pressure (MP) steam is separated to Steam trap occurs near Elbow ( the Elbow) at the point of impact of the Flow by Steam flow in Line that runs Steam trap that resembles a Two-phase.

 

Case II:

Erosion at the opposite tee fitting of the Low-pressure (LP) steam condensate pipe is caused by the two-phase flow (Flash steam + Liquid condensate) from the pipes that condensate from the steam trap that is combined.

Case III:

When Liquid Condensate runs through the Control valve, some are turning to Flash steam becomes Two-phase flow and flow turbulence ( Turbulent) resulted from Erosion , especially at the point of impact on the joints of the various (Elbow, Tee).
