Dear Experts,Greetings to all of you.We got a situation in the project where the following observation has been found.1. pipe - CS 10" dia.2. orifice flange SS - 10" dia. - Flange has a long protrusion of the neck towards the bevel end that gets inside the pipe. see attached picture - red mark is where the pipe ends landed.

The joint has been welded with the result as shown in the picture below.
<image.png>The decision is to weld the pipe despite the overlap. The production proceeded the welding activity without trimming the flange end (by machining or grinding as we suggested) to meet the same surface level of the run pipe. After welding the joint went thru RT and passed the test.We consulted the design engineer for this reason but no concrete decision was made so the client production team gave final disposition to proceed with welding.I would appreciate your thoughts on this matter. What do you think? what would be your recommendation? what problem do you think this would bring in the plant operation? did you ever encounter the same issue before? if so, what did you do? if not, what would you have done differently?Best Regards,Anthony D.
