PURPOSE: To produce a pipe made of fluoroplastic, especially, polytetrafluoroethylene in which a conventional defect is eliminated.
CONSTITUTION: In a method for producing a pipe made of fluorplastic, especially, polytetrafluoroethylene, the winding angle between the axial line of a tape and that of the pipe is set to about 90° and a winding part is largely superposed on a first winding mandrel of about 30-100 layers of tapes and, subsequently, second winding 3 wherein the angle between the axial line of the tape and that of the pipe is set to about 45-90° is performed to first winding 2 and the second winding 3 is performed in such a state that the winding angle between two successive layers is alternated without generating the contact of the winding part and continued until desired total pipe thickness is obtained.
