The existing U-shaped branch pipes which are manufactured by a stamping method are mainly manufactured by the following steps: punching and flanging the middle part of the pipe blank by a punching die to form a main pipe welding hole, then bending the main pipe welding hole to form a branch pipe, and finally welding a connecting pipe on the main pipe welding hole to form a branch pipe. Although the branch pipe formed by the manufacturing process has low processing difficulty and few welding points, the height of the main pipe hole formed by the flanging is compensated by the radial flow of the material of the pipe blank, so that the flanging height of the main pipe welding hole after the flanging is very short and is far smaller than the diameter of the pipe blank. When the connecting pipe and the main pipe are welded, the welding strength is very low due to the short welding matching length, and if the branch pipe with the structure is applied to an air conditioning unit, the welded part is easy to be detached or the welding line is easy to crack during installation and construction, so that the serious result of pipeline burst is directly caused.
