The test piece has been in the simulated heat exchanger for 50 days; what type of corrosion is this in carbon steel? How to control it?

We use a chemical agent for control. Setting aside this agent, we will focus on analyzing the forms and causes of film corrosion, as well as the indicators that need to be monitored. Thank you
No one has replied to this post; I’m not sure how to respond given the medium and operating conditions
I don’t know what the internal fluid is, nor do I know the flow rate or pressure. Additionally, I’m unaware of the location and material of the attached pieces... I might need you to explain it in more detail. Based on just the photos, one can only guess that it’s a corrosion phenomenon caused by a potential difference
