    Thoughts about this weird microscopic corrosion

    Flow rate is zero, system gets filled and stays filled. This is almost always exactly what happens to us. They hydrotest and will usually drain it but no flushing, so some water gets left in the tubes. As these tubes are globally used and I'm stuck in one place all I can do is look at the tubes...

    Thoughts about this weird microscopic corrosion

    Interesting that you say argon doesn't provide a bright anneal... we switched to argon because we had sensitization issues in the past, it has since been solved, no GB carbides or sensitization, tubes are shiny and bright to me (I'm young and dont have any experience with heat treating so I'm...

    Thoughts about this weird microscopic corrosion

    Unfortunately I cannot. We are aware that tap/city water will contain ions, especially chlorine, and in most cases they eventually corrode. I've tried to push higher ups to focus on the water more but for whatever reason everyone refuses to do anything about the water. Apparently customers are...

    Thoughts about this weird microscopic corrosion

    Testing the water is harder than it sounds, I've tried to get them to do it. These were actually from 2 different systems on different continents as well. Not DI, just straight tap water/city water. I'm not quite sure what you mean by "how is the integrity of the wall thickness measured." Well...

    Thoughts about this weird microscopic corrosion

    Hello forum, interested to hear what thoughts y'all may have about this really weird looking corrosion I found. Parts are thin wall 304L stainless tubing, annealed. They get filled with good ole tap water but failures are very random, sometimes they'll last a few days, sometimes a few months or...
