Did you see the PPE they were wearing ? I mean NOT wearing ! No safety glasses and even no shoes on that one dude ! India maybe ???

I'm shocked they're even a one-piece valve...some American and ALL offshore valves used to have the valvestem friction welded onto the head of the valve. Crazy to watch a valvestem spinning a ga-zillion rpm clockwise and a head of a valve spinning in the opposite direction being brought together to friction weld into one complete valve...

aaaah, the good old days lol

Friction welding is used a lot when mixing different metals into one piece.
