How to inspect the quality of the enamel surface on the lid of a glass-lined reactor after it arrives? Just like in the photo below, when it’s held in this position, how can one see the inner surface? It’s not possible to turn it over

Which company manufactured this? The appearance quality is good; the oxide scale has been removed thoroughly!
Just hang a lifting lug and you can see inside.
Once it can be lowered, it can be turned over; it needs to be turned over for inspection. The first method is visual inspection, that is, looking at it with the eyes. The second method is to use the same inspection techniques as those applied to powder coating, namely using a high-voltage spark detector; fluorescent materials can also be used for inspection
Stand up, view from the side? Can a forklift do it? It’s pretty dangerous anyway to inspect it using a forklift…
How do 12V batteries generate pulse voltages of several thousand volts or even tens of thousands of volts? What is the principle behind this, and isn’t it dangerous to use them?
I haven’t studied the principles behind it, but high voltage requires a step-up transformer; it’s relatively safe to use. Electric batons are used just the same way – as long as you don’t operate them improperly, there’s no problem.
Give me 500 yuan and I’ll find it for him in no time
