Why does the pigtail pipe under the hydrogen production furnace develop magnetism after operating for a long time?
At high temperatures, the structure of the material changes
Was the magnetism checked before installing the lower pigtail pipe, in all areas – the straight sections as well as the curved sections? What is the maximum temperature at the outlet of the lower pigtail pipe? Did you notice any magnetic areas after operating it for some time? There are certain requirements for the working conditions when producing it.
It has been checked; it basically has no magnetism.
