Yesterday I got to weld on my first td williamson 3 way tee.  I welded it on an existing 4 inch steel gas main.  I have welded on lots of 2 inch tees but I have to say the 4 inch is quite a bit different.  We tested the new main we tied in and tapped the new tee and completed the tap.  I love it when a job like that comes together.  Just wanted share what a great day I had.  Thanks.  Robert Turney
