I need some info on tubing-welded t's/welded branch, t sizing etc..
I work in the compressed natural gas field so theres a lot of tubing that gets installed and modified. I was on a location the other day and some made mention that one of welded T's ae incorrect according to code. We have a run of Swagelok .750 x .109 that has 4500psi on it. There's 50 welded t's on this run and all of the t's are 3/8 stainless. I was told that this is considered a welded branch and not a T and also that the regulation for any welded T is to be no more than a 1/4 the size of the tube its welded to.
Ive never heard any of this and I asked where this code is but no one knew.
So my questions are
#1. What code regulates tubing
#2. Whats the difference in a welded T vs welded branch
