The invention provides a prefabricated pipe pile and a manufacturing process, the prefabricated pipe pile comprises a common concrete pipe, a reinforcement cage and a steel mold, sleeves are horizontally arranged on the periphery of the surface of the common concrete pipe, and spiral reinforcement arms are welded to the sleeves; a reinforcement cage is bound on the surface of the common concrete pipe, a steel mold is arranged on the outer side of the reinforcement cage, and constructional steel bars are vertically arranged in the common concrete pipe; an ultra-high performance concrete layer is arranged between the reinforcement cage and the steel mould; and a switch valve is arranged on the steel mould wall of the steel mould. According to the manufacturing process of the prefabricated pipe pile, the problem that in existing pipe pile production, an inner film is difficult to demould is solved, the problems that a common pile is low in durability and poor in corrosion resistance in a complex environment are
