Can electric heat tracing belts be used to heat plastic pipes or plastic storage tanks?

Can electric heat tracing belts be used to heat plastic pipes or plastic storage tanks? Is the liquid heated through heat transfer through the wall, or is the air in the insulation layer simply used for external insulation?
Electrical heating only serves for external insulation. No heating.
Sir, where is the thermometer probe usually installed for insulating storage tanks?
I think I previously bought an “enhanced electric heat tracing tape” to heat PE pipes
You can use self-regulating electric heating tapes to prevent excessive temperatures from damaging the plastic pipes (containers). In theory, if the power of the electric heating tape chosen is sufficient and it is wrapped tightly enough, it will be able to provide heating; it depends on how much heat is needed. I’d like to remind you that plastic materials have poor thermal conductivity; the heat transfer coefficient when heating from the outside is very low. A very large heat transfer area may be required, and if this area exceeds the external surface area of the pipes and equipment, heating will not occur.
It can be used; the temperature isn’t high – it’s at a level that can be touched by hand, around 30 degrees or so.
If it is a PFA tube, it can generally be heated to around 70 degrees.
You can try electromagnetic heating, which can directly heat the liquid inside
