General view of the 2" branch line that was supporting an instrument in a 12" gas piping of an offshore unity. The branch line is composed by a seamless pipe welded to a weldolet (left side of the figure) and to a flange (right side of the figure). The leakage is associated to a through wall cracking in the middle of the pipe length. The cracking is not evidenced in the figure, since it is too thin. See the schematic drawing in the next figure
