PURPOSE: Iron pipe coating apparatus is provided to reduce coating time by coating the inner side and the outer side of iron pipe at the same time, thereby facilitating the coating process, and to prevent the use of toxic material. CONSTITUTION: An iron pipe comprises: a iron pipe rotating part(110), in which iron pipe(10) heated to 170°C-300°C is mounted, rotating the iron pipe; a outside coating part(120), which is arranged on the top of the iron pipe to be separated with the iron pipe, spreading epoxy powder on the outer side of the iron pipe; an inner movable coating part(130), which is arranged on one side of the iron pipe rotating part movably in order to be inserted into the iron pipe, moving while spraying the epoxy powder to inside the iron pipe; and a flying powder absorption part(140) covering opened both side of the iron pipe mounted on the iron pipe rotating part, and absorbing epoxy powder scattered due to spray of the inner movable coating part into the iron pipe.
