Aspect of the stub end, that is used in combination with a lap joint flange. In this case it was prepared from a seam welded pipe, longitudinal, also with circunferential weld to the stub face (which means it was not flared). The cracking is circunferential in the non painted region, not associated to any welded area.

Aspect as received, side A, of the part removed from the rectangular tube that was manufactured from plates, and originally presented two welded seams (not included in the sample). Close to the edges of the sample, where probably were the corners of the rectangular tube, the degradation is in a highest level. Three samples were analysed, with different thicknesses (indicated in the figure). Side A is the side that was in contact with the reaction (product side).
