PURPOSE: A corrugated pipe type nonmetallic expansion joint is provided to increase durability by absorbing displacement including compressive expansion with high thermal insulation and high heat resistance and to immediately assemble or repair an expansion joint. CONSTITUTION: A corrugated pipe type nonmetallic expansion joint comprises an inner insulation layer and an outer reinforcement layer(20). The inner insulation layer is comprised of an inorganic material including thermal insulation and is formed as a shape of a corrugated pipe. The shape of a cross section includes a form divided into a plurality around the center. The outer reinforcement layer warps outer periphery of the inner insulation layer and is formed by coating a silicone resin to the outer periphery of the inner insulation layer.
