Weldolet branch connection looks so strange... (photo) 1

[QCJT]

Hi all,

Could this be right (see photo attached)??

Generally speaking, which standard specifies how the weldolet branch connections shall be fitted? I mean when it's set it, set on etc. and what's the proper orientation (meaning which side goes onto run pipe)?

Thanks in advance for all kinds of feedback

QCJT,
Your original post questioned the correctness of the orientation of the fitting and then later you mentioned it was installed upside down.
Then it was supposedly removed, installed correctly and rewelded ?
Unless there is something wrong with my eyes both photos show the fitting installed the same way - the first shows the weld is incomplete and the second shows the weld completed ?
Cheers,
DD

Maybe "upside down" meant "on the underside of the pipe"? Attached sketches with notes are always a good idea especially if there's a language barrier.

Gator, well spotted - they didn't turn it. Simply completed the welding. And to be honest, we are confused with this "orientation" thing. In the first image it seems that the weldolet should be flipped but now, when they filled up and completed the weld it looks allright...
Agree?

QCJT,
The final photo does not appear to have a radius at the weld to main juncture as is indicated in the sketch posted by Littleinch. So there is still a stress raiser at this junction. Hopefully there is no significant cyclic loading. Once seen a 6"nb weldolet on a 12"nb line completely snapped off due to a combination of circumstances, all because of a stress raiser.

Denstan, thanks. I agree, it is not the smoothest transition but this isn't for cyclic loads so should be fine. And it is much better that what was there before.
