The invention discloses a one-time formed rubber double-face rubber hose and a process thereof in the technical field of rubber pipelines. The one-time formed rubber double-face rubber hose comprises an inner rubber layer. A reinforcement layer is arranged on the outer wall of the inner rubber layer. An outer rubber layer is arranged on the outer wall of the reinforcement layer. Through one or two extruders and a co-extrusion die, the inner rubber layer and the outer rubber layer are extruded on a strip blank once, the procedures that inner pipe extrusion is conducted, an inner pipe penetrates into the strip blank, outer pipe extrusion is conducted, and an outer pipe penetrates into a rolled hollow semi-finished product are completed, and the procedure of strip overturning is omitted; and then the one-time extruded semi-finished product is pulled to pass a cooling water tank area and hole rolling equipment and is pulled to a vulcanization area for vulcanization, and after vulcanization, direct pressure testin
