Disclosed is an apparatus and method for manufacturing a pipe having multiple layers. The apparatus comprises a winder having a cylindrical shape, a driving means for rotating the winder, an internal and an external layer extruder for extruding resin into resin sheets to form an internal layer and an external layer, respectively, a middle layer sheet supply device for pulling out a middle layer sheet using a pair of rollers from fused material, and a pressure roller for pressing a resultant structure, in which the sheets are wound around the winder. The manufacturing apparatus and method according to the present invention have advantageous effects of making it possible to manufacture a pipe having multiple layers and having high internal and external pressure strength, sufficient hardness to endure thermal shocks, and good durability and reliability. |
