Teachers, please help find out the reason why this heat exchange tube broke.
Thread Content
The heat exchange tube material is 06Cr19Ni10, which is 25 of 30408* 2 users of heat exchange tubes said they discovered leaks after being put into use for 2 weeks. After testing, they found that there were many leaking tubes. After pulling out the leaking pipe, it was found that the heat exchange pipe was broken. Below is a photo of a broken heat exchange tube. Teachers know whether this situation is due to material selection or the quality of the heat exchange tube.
First, check the spectrum to see if the ingredients are qualified. . Even a small amount of deviation will not cause such a break. Then analyze the medium composition working conditions. . . I guess the latter reason is more likely
Check the chloride ions in the medium. It must be seriously exceeded. Please change the material.
The heat exchange tube looks like this after 2 weeks of use. It is probably a material problem. You can write down your working conditions and we can help you analyze it.

How high is the material temperature? Does the material contain hydrogen?
1. What kind of medium are you using? If the chloride ion content exceeds the standard, it will definitely not work. 2. If the medium is a very acidic medium, then it is a matter of material selection! 3. If there is no problem with the medium and the material selection, it is a quality problem. However, if there is a problem with the material, it is best to test the pipe with a sample and use a chromatograph to rule it out.
It’s really difficult to analyze without working conditions, but it’s like this after just two weeks of use. It’s probably a material problem.
The original poster: What is the specific working condition of the heat exchanger? It feels like this is not a quality issue with the heat exchange tube. If it is a quality problem with the heat exchange tube. Then this equipment manufacturer is a bit too bold.
What medium is transported and what working conditions are used? You can’t tell just by looking at the picture
