I worked at Kennedy Tank and Manufacturing in Indianapolis, Indiana in Engineering. I ordered heads and parts for pressure vessels but never seen this operation, Thanks.
What did that guy throw on there at 2:13 that looked like a pizza? Is it some kind of mold release agent that mostly burns away to leave a greasy soot? I would think you wouldn't want the extra carbon but maybe that's the purpose?
I've been involved in a lot of engineering projects but that takes the cake.Imagine someone coming up with the idea and it not working after all the investment.Well done
Why did the guy throw a piece of wood in at 2:13? It immediately burst into flames. The charred remains can be seen when the bowl is removed at the end.
That's exactly what it's for. The wood turns to carbon and prevents the inner die from sticking to the part or otherwise being marred by the workpiece. Same with the oil they use- turns to carbon and becomes a non stick coating.
Sideslip - it also inhibits scale formation. The burning wood consumes all the oxygen near the metal. Did you notice the scale removal just before the guy threw in the chunk of wood?
@@JoeKyser That's is not a wok but the dish end of a cylindrical vessel normally seen in Pressure vessels or Petroleum tankers. It is later welded on both ends of the hollow cylinder to form the vessel.
This compared to press forming is very energy inefficient, you run a heat oven plus a press. Rather than just a hydro press. And it seems you can only run one size diameter at a time based on the press.
The end of a pressure vessel (to store pressurised gases) . They would make another one then weld to each end of a steel cylinder. Much stronger than having flat ends welded onto a cylinder
