Abstract

PURPOSE: To perform efficiently the pressure molding, by pressing the inner surface of a resin pipe, which has been centrifugally molded, by a press roll that has a plurality of projections on the outer surface with the height thereof, the width of the top thereof, and the pitch thereof being specified.
CONSTITUTION: The projections of each press roll has a height H such that 1mm<H<5mm, a width d of the top such that 1mm<d<5mm, and a pitch P of the projections such that 2mm<P<10mm. The press rolls 7 are rotatably attached to arm levers 7 to press and mold the inner surface of the resin pipe 8 that has been centrifugally molded.
