    Minimum Pipe Wall Thickness for Welding - CR4 Discussion

    Dec 12, 2009 · there are various codes ANSI,AWWA etc stipulate the minimum thickness requirement. as such there is no requirement from welding point of view. however thickness below 4mm is difficult to be welded. as a practicing engineer we have seen a ratio D/T more than 100 is considerd to be very thin cylinder and not structurally stable and may need stiffening inside.
