Severe pipe damage
Severe pipe damage
(OP)
We are Constructing a 230 km buried pipeline. The pipeline is completed and hydrotested.
During the perming, one of the loaders hit the pipe, leaving a severe damage in the pipe, as shown in the attached picture.
I recommended to remove a 2 meters length of the pipe, and weld a new pup piece.
Since the new welds cannot be hydrotested (easily), i recommended to go for both RT (D4 film) and manual shear UT. The RT is to be supervised and interpreted by NDT level 3.
Any suggestions are welcome.

RE: Severe pipe damage
Other than that I'd just x-ray the new welds. This kind of repair is relatively common and I've never heard of anyone hydroing a 230 km line for a repair weld. Doing a UT (or mag flux or die pen) wouldn't hurt anything, but doesn't add a whole lot either. In this situation I just x-ray.
