Abstract

PURPOSE: To prevent the ringworm corrosion of steel tubing for an oil well in an easy and effective manner by upsetting the material of the tubing at a specified temp.
CONSTITUTION: The material of tubing is upset at 1,100W1,200°C to prevent ringworm corrosion which occurs at the boundary between the upset part and the base material part. In this temp. range a little structural difference is observed in the upset part and the base material part or at the boundary, and yet a large grain size difference is eliminated.
