とするパイプの溶接取付部構造。 In a mounting structure in which a pipe having an outer diameter that matches a hole provided in a side wall of a tank, etc. is fitted inside, and the peripheral part of the pipe in contact with the hole is fixed and integrated by welding, the end of the pipe is exposed. An enlarged diameter part is formed by diameter enlargement processing such as panda processing, and a hole in the side wall of the tank is formed to match the enlarged diameter part, and the enlarged diameter part is fitted into the enlarged hole to expand the diameter. A structure for a welded pipe attachment part, characterized in that the periphery of an enlarged diameter part in contact with a hole is fixed by welding to increase the section modulus of the part.
