The double thin pipe manufacturing equipment comprises a 1st thin pipe forming apparatus and a 2nd thin pipe forming apparatus. The 1st thin pipe forming apparatus has a 1st winding roll(1) to roll and release the thin plate, a forming apparatus(2) to form the released plate into a cylindrical shape, and a lifting apparatus(3) to move the 1st thin pipe. The 2nd thin pipe forming apparatus, which is placed behind the 1st thin pipe forming apparatus, has a 2nd winding roll(1) to roll and release the thin plate, a forming apparatus(2) cylindrically surrounded over the upper side of the 1st thin pipe to form the released plate, and a lifting apparatus(3) to move the 2nd thin pipe.
