What's the difference between the field cut and the shop cut? There isn't an AHJ in the world that can tell if I shop drilled or field drilled. At my last company often enough we'd shop drill. Or the shop welded cut out? Or is someone saying they all need to be attached? I don't see where any need be. And the requirements for retrieval in no way shape or form requires attachment. How exactly to you show compliance with the dimensions for groove depth and width, thread specs, etc? 'Cuz you know to an extent there is slop in these and they hold at least for a while outside specs. Do ya'll hang gauge templates to every fitting to show compliance? Do you hang a weld x-ray on each weld? 'Cuz you know there are requirements that can't be readily seen if they are in compliance. Do you hang the ball peen hammer next to the 'fixed' dripping welds that occasionally occur?
Every seen the weld scraping from the factory produced pipe get dropped and adhered to the inside of the next pipe in the formation line? Now if I knock them loose I can show they were removed by attaching. Wonder how you show compliance if they didn't occur in the first place? My real point in my ramblings is there comes a place where we have to trust all involved did their job right. Do things get left in the pipe occasionally? Sure do, but we need to tackle keeping the valve open before we get into the minutia of the other possible failures which all together don't add up to a lot of failures.
