<p>Disclosed is a branch pipe connector for welding pipes which can simplify and facilitate a manufacturing process in a factory, reduce cutting and welding and occurrence of a welding inferiority of defect, make a change in design, etc., after the installation easy, and facilitate transportation, storage and loading by being miniaturized. The branch pipe connector comprises at least a curve expansion portion (5, 15, 25, 35) to be formed with a connection portion of the main pipe (1) and the branch pipe (2), being divide from the main pipe (1) at a main pipe joint surface (4, 14, 24, 34) to be joined to the main pipe (1), and being divided from the branch pipe (2) at a branch pipe joint surface (3, 13, 23, 33) to be joined to the branch pipe (2).</p> |
