Can a 6-meter-long 304 storage tank with a 5-mm diameter be straightened using flame heating?
The temperature is difficult to control, and sensitization is likely to occur; do not use flame shaping

No, stainless steel has a high degree of thermal deformation, making it difficult to control. Additionally, heating causes sensitization of the stainless steel, which affects its corrosion resistance.
It’s best to send a video, indicating the relevant usage data and materials. For those with minimal deformation, it is best not to take any action.
It is not recommended to use heat treatment for thin sheets, let alone stainless steel thin sheets
Heating the orthosis with a flame may cause greater deformation
It cannot be corrected by flame; it is sensitized in the 450–800°C range. If correction is necessary, mechanical correction should be employed.
Owners who understand this certainly won’t agree!
There’s a bad idea: if the area that needs to be altered is small, cut it out and replace it with a new piece, then grind away the weld
For atmospheric pressure storage tanks, the method mentioned above can be considered.
