Abstract

PURPOSE: To obtain a steel pipe material for a stretch reducer prevented from breaking at and near a welded part by giving a proper balance between strengthes of a mother pipe and a joint.
CONSTITUTION: For the continuous manufacturing of a small-diameter pipe by a stretch reducer, the strength rate of a welded joint part to a mother material part in a high temperature of 800W900 degrees C in a pipe material previously prolonged by welding is taken in 1.00W1.30. Material A steel is given by connecting carbon steel pipes by friction pressure welding, and is processed by stretch reducing after external beads are cut off. In this case, since the mother pipe and the joint part are given an essentially equal quality, the strength of the pipe joint is almost equal to that of the mother pipe in a high temperature of 800W900 degrees C
