Corrugated pipe formed by pressure

The utility model belongs to the technical field of corrugated pipes, and particularly relates to a pressure forming corrugated pipe which is a continuous corrugated pipe body formed by a descending section, an ascending section, a peak arc section, a valley arc section and a pipe neck section through pressure forming, the radius of the peak arc section and the valley arc section is R3-28mm, an arc-shaped section protruding outwards is arranged on the descending section and/or the ascending section, and the outer side of the arc-shaped section protrudes outwards. The pipe neck sections are located at the two ends of the continuous corrugated pipe body, and the arc-shaped sections are in a circular arc shape or a triangular shape or a trapezoid shape. Compared with the prior art, the corrugated pipe has the advantages that the strength and the elasticity of the corrugated pipe are effectively improved through the arrangement of the arc-shaped sections; and 2) the bending radius ratio of the peak arc section to
