Treatment of pipeline scarring
Thread Content
There is severe scarring inside the pipeline, with calcium sulfate as the main component. Are there any effective methods for cleaning it?
Calcium sulfate is slightly soluble in water and insoluble in acids; if the problem is severe, the pipes have to be replaced
Handling recommendation: 1. Remove the pipeline and purge with steam； ⒉Replace the pipe ； ⒊Improve the process to eliminate calcium sulfate.
If you are sure it is calcium sulfate scaling, use a calcium sulfate cleaning agent with a pH of 7.0±0.1; it is non-corrosive, reacts rapidly and intensely, and removes calcium sulfate at a rate visible to the naked eye. If you’re interested, I can send you samples for free to test; I guarantee they’ll work well for you. Of course, the prerequisite is that you must be sure the scale sample is calcium sulfate.
