only heats the inside so no use
you'd need a big kettle to pour for 1 minute
and what a pain compared to bunging the pipe in the kettle

Or pour in hot sand, give it some support while bending/moulding?

sand gives you no temperature regulation
only heats the inside
and the last thing the pipe needs is support. If you heat it to the point where it does, ie above boiling, the result's misshapen.
