    Here I am standing in front to give an idea of how big it was. I am 6ft tall and this was in the ground about 10 feet or so.

    Let me know what you guys think.

    PS Yes i know there is a lincon welder in the shop. The welding truck has a trailblazer 302g, 2050 plasma, 12rc suitcase welding. Trying to get my boss to buy a XMT304 for the shop. Think I have them sold on the idea.

    Very nice work, was it x-ray. The biggest I ever worked was over 60 inches in diameter and it was for a dredge boat that was to be used in Florida to dredge a channel . It did not require any kind of NDT. Again I would like to say very nice work.

      Nice work.

      I would like to see the machine that is used to bend that large of pipe.

        If you are refering to the 60 inch pipe all of the ells were rolled out in halves in the heavy plate shop and then welded and mitered to suit. The majority was straight and also rolled in halves and butted together . The flanges were cut out of plate and drilled. The wall thickness was 1/2 in and after welding was lined with some type of coating. We did this job yearly in the shipyard as it was worn out completely when the dredge ship came in. Nothing was bent on pipe bender. Hope this explanation helps.

            GaryM--What wire did you use on that? Did you use wire in the field also or stick? Looks like a fun job, very nice.

              Thanks for the great replys.

              The elbo I think is a cast fitting along with the Tee. Only used one Tee out of 6 rest were coped cuts.

              For wire all the shop welding was with ER70S6 .035 did not have drive rolls for anything else. Field was the same weather permitting. other wise 7018 3/32 and 1/8 rod.

              here is a couple more pics of the project.

              I guess the hardest part of the project was the oval pipe. Every thing was used and the gas pipe(green epoxy coted) was really bad.
