PURPOSE: A fluid transfer pipe is provided to transfer large amounts of fluid by swirling the fluid through the spiral projection and maintaining the fast flux. CONSTITUTION: A fluid transfer pipe(10) comprises an outer peripheral pipe(100) and a spiral projection(200). The outer peripheral pipe is formed into the cylinder shape. The fluid is transferred through the outer peripheral pipe. The spiral projection is spirally formed in the inner circumference of the outer peripheral and is projected to inside. The cross section of the spiral projection is formed into the trapezoid or the semicircle shape.
