[REQUEST] Video Courses about Valves, pumps, drilling, refinery etc.

Hello, fellow engineers!
I found on the internet the following video:

and many more pieces of videos on various engineering subjects.

I want the whole documentaries ( or training courses ). Could you help me track them down? I'd love to add them to my collection because of the very objective style of presentation. I understand the mechanics sooooo good from those videos than reading any number of pages on the subject.

Thank you all for your time! Any hints about them are welcomed. Don't be shy!
