The invention relates to a ribbed noise reduction composite air pipe. According to the air pipe, an air pipe body is integrally formed by adopting a prefabricated ribbed plate, reinforcing ribs on theribbed plate are formed through pressing and protrude out of the outer wall of the pipe body, sound absorption material is attached to the reinforcing ribs on the outer wall of the pipe body, and anoverall skin layer is arranged at the outer side of the sound absorption material. According to the air pipe, under the condition that the structural strength is guaranteed, the requirement for the wall thickness of air pipe base material is lowered, the integral preassembling is realized, the reliable structural strength and noise reduction and heat insulation capabilities are realized, the fieldinstallation is convenient, the maintenance is convenient, and the air pipe can be widely applied to heating and ventilation engineering, and is mainly applied to air supply and return pipelines of an air conditioning system,
