  • Water pumping station

    Customer asked me to come and weld one flange in an underground pump house upgrade several weeks ago. Over the last weeks been back numerous times and I have maybe 50 hours here. Nothing fits as engineered. Making it up as we go. Hopefully finished up last night. 6" flange with no room btwn wall. Made sure I welded the inside real good and did best I could on outside. I can't mirror weld.

    The black flange is what I welded on. Then once they piped it I had to cut off most of the pipe supports and make new ones plus three pump mounts. All welded to floors and walls of metal bunker. Last thing was fit and weld two of the pump outlet connections. Had to be fit in place and tacked because nothing is square, or inline. Ran out of time yesterday as we were limited to being in there from 7:30 until 3:00pm. Brought them back to shop to weld out.

    Mild steel just sanded and cleaned. Dropped at their shop 8pm last night so they can epoxy coat and install Monday. They don't look so bad to make but the flanges aren't level with each other or in line so the flanges are rotated off of center line. This is why I fit and tacked in place, then removed to weld vs just taking measurements and building on my table. 2-1/2" pumps to 4" supply line. The pipes are upside down here as to how they actually go.

        Welding pipe I find challenging for me. I don’t do a whole lot of it and I can be impatient with it. It’s pretty much the only thing I make coupons for and practice before I do it. I’ve proofed out welding processes before starting, but I actually keep a few pipe coupons on my shelf. Pipe weldors work for years to get super good at it, I dang sure ain’t no pipe weldor.

          Had to go back a few days ago. Engineer wanted two supports for the two pump outlet pipes I fabbed. The tall ones in pics.

                Great work, always a challenge to retro fit existing installs
