Let’s hope you purged with nitrogen. Those welds took too long to bond id expect it to be fast with oxi acetylene, make sure u clean you joints before brazing even if it’s brand new pipe work.

useful video, thanks
but before you insulation your Y-branch you should test pressure, because if pressure become decrease you must go check Y-branch weld.

Long sweep 90s not short 90s. Don't route pipe so they touch and rub against each other.
