The quality inspection of stainless steel heat exchange tubes is to find problems in time and deal with them, reducing unnecessary troubles in use.
There are many ways to inspect stainless steel heat exchange tubes, and the four most common ones are visual inspection, pressure test, chemical composition analysis and metallographic inspection.
Among them, visual inspection is to observe the surface of the stainless steel heat exchange tube with the naked eye to see whether it is flat and smooth, without obvious scratches, bumps, oxidation and other phenomena; pressure test mainly detects whether the stainless steel heat exchange tube has water leakage, cracking, deformation and other problems, and also detects toughness and bearing capacity; chemical composition analysis is to detect whether the chemical composition of the stainless steel heat exchange tube meets the standard; metallographic inspection mainly detects whether the metallographic structure of the stainless steel heat exchange tube meets the standard.
Only stainless steel heat exchange tubes that have passed these tests and passed the results can be put into use.
