Heating pipe bent too much?

For the first picture, I wouldn’t really have any concerns – but the second one is a bit strange; it somehow suggests that the pipe is rather thin, doesn’t it? What kind of grid is that? I just checked with us again; no turn was possible under a 25 cm radius.

Yep, it's the same for us.

So, they will now cut out the piece and attach the new piece with 2 couplings, the question is how does it look at that spot in terms of oxygen tightness?

If that is done properly, it should be tight...

I have my doubts about the people up there, but won't there be pressure once everything is finished?

That's how it looks... make sure the clutch gets a protective sleeve.

Normally, you then press off ...
