Hello!
In heat exchanger (U-type) I've problem with erosion/corrosion at beginning of tubes in heat exchanger,near tube-sheet where steam enters.i suspect cavitation is problem. on tubes there's a channel of erosion in the middle of tube where material is gone and tube is very thin in that channel,as tube continues channel is smaller and smaller,and finally there is normal cross-section of tube.medium in tube is 4bar steam used for heating methanol in shell side
anyone had experience with this? how to try solve this problem?
tnx
