Abstract

PURPOSE:To prevent the groovelike corrosion of weld zone without adding expensive alloy elements, by heat-treating the seam welded steel pipe at a fixed temperature. CONSTITUTION:Seam welded steel pipe is heat-treated at 730-780 deg.C within 30min by the heat treatment furnace or high-frequency induction heating furnace and is air-cooled. Generation of groovelike corrosion by the service water, sea water, industrial water at the weld zone can be prevented by aggregating finely dispersed carbide on the weld zone in a short time by the heat treatment.
