Abstract: The present disclosure relates to a composite pipe having improved bonding strength between heterogeneous materials, which provides continuous bonding strength by chemical bond between heterogeneous materials, thereby preventing separation between the heterogeneous materials even at a high temperature and a high pressure, so as to replace a metal-based pipe used in fields of industry demanding heat resistance and chemical resistance, and an apparatus and a method of manufacturing the composite pipe. Accordingly, strong bonding strength according to chemical bond in the unit of nano between the heterogeneous materials is achieved, so that separation between the heterogeneous materials is not generated even at a high temperature and a high pressure, thereby being capable of further expanding the applicable fields of industry.
