Those look like your solution. Also water can take more heat with less trouble than air heaters. I've had air heaters start melting things, etc. You can just install those in the side of a 55 gal barrel with a bulkhead fitting, or yes, weld the appropriate plumbing fitting to the side of the barrel. Might even be able to install them into a section of pipe with Ts and run water through it to cool the elements.
Note that water heater elements are NPSM (National Pipe Straight Mechanical) and not NPT. So you need that type of half coupling or "bung" to weld in. The vegi-oil people seem to have this sort of stuff as they build water heater elements into things.
