  • Municapal Water Tank

    I am watching them build a large water tank near me. Amazing work.

    It is the kind with a large cylindrical concrete tower and a steel tank on top. It looks like they are stick welding and the large plates are 1/2" thick. They weld all day in this 98 degree heat on hot metal. I am impressed.

    I was just wondering if any of you guys have ever worked on water tank. Are they welded inside and out? Are special qualifications required.

    Should be welded inside and out. Depending if it is preasurized or not it may even be xrayed. As for welding qualifications that depends on if it is a coded tank or whatever the company building it requires. I believe if it is a coded tank you must be certified in whatever process/procedure they are using.

      Worked on them many years ago, welded inside & out, worked off of scaffolds running 3/16" rod. Got paid by the rod, kept rod butts in a bucket & turned them into the time keeper at the end of every shift.

          The Boilermakers NTD[national transient division] does this type work. Special breed of folks and the ones that do it regular are very effecient at it.

              Payed by the rods??? Man, now I've heard it all. This should be against the law.

                Well to me it seems the fairest way...you weld hard you're paid for it...

                yous sleep, smoke, drink, dream you're also paid acordingly...

                  could be one of several

                  codes. AWWA , API , ASME and others. Worked with NTD Tankies for quite a
                  long time off and on. If you belong to the NTD they have a set hourly rate like
                  any Boilerrmaker. The NTD is out of Oklahoma I think.

                  Most field erected tanks are welded both in and out and most are spot x-ray.
                  NDE depends on design. Big difference between flat bottom tanks and
                  pressure vessels.

                      Actually they disolved the actual National Transient Lodge and the construction locals assumed them. They also changed the name from National Transient Lodge to National Transient Division since it's no longer a actual local.Lots of talk about this at the recent Boilermakers Convention.

                        Mr Showdog

                        Thanks for the info. It`s been quite some time since I have seen my old friends.
                        Worked for Reco, Old Dominion. Worked with Capital City and Chicago Bridge
                        on some projects. No business for an old guy and wouldnt even think about
                        jumping scaffold.
