Erosion (?) into a seawater pipe
Erosion (?) into a seawater pipe
(OP)
Dear All, we've received for analysis a CS forged spool (about 16" diameter) used to connect a butterfly valve to an heat exchanger. The H.E. is used to cool process water using seawater as cooling medium: into the forged pipe flows seawater that goes into the H.E.
The internal surface of the spool is completely white (bright) and has the same appearance of the sea surface view from high above. Could it be erosion? If so which could be the possible cause since the butterfly is always open and there's no sand into the water? Could the hardness of the forged item have any influence?
Thanks for the help

Are you sure it's carbon steel? Is a magnet attracted stongly, weakly, or not at all?
