To provide a method and an apparatus for processing the surface of a resin pipe capable of easily forming irregularities on the surface of the resin pipe by a simple apparatus.

Since the resin pipe 12 is vibrated by a vibration means 15 before it solidifies, irregularities 14 are formed on the surface of the resin pipe 12 by the action of a centrifugal force, an inertial force and the like, and the irregularities 14 can be solidified by rapidly cooling the surface of the resin pipe 12 in a cooling water tank 13. If cooling water 18 can pass through not only the outer surface of the resin pipe 12 but also the inner surface of the resin pipe 12, the irregularities can also be formed on the inner surface.
