Waveform relates to a steel pipe and an apparatus for manufacturing the same. Corrugated steel pipe includes a tubular body and a deep rock. The tube is a steel sheet having a plurality of wave portions in the width direction at a central portion is formed in a spiral wound. Lock mandrel comprises a first in which one side in one direction of the first water-tight material is inserted made of a viscoelastic polymer material on the first bending groove defined by the bent portion, the sides other side of the steel while the steel sheet is wound in a helical bend in a steel sheet the second bending portion soon as the insert in the first bending groove as well the first bending part in the first state into the second bending grooves, bending the first and second number with miljae defining a second bent groove is bent in a bent portion in the opposite direction It is formed by a groove pressed.
