Abstract

PURPOSE: To prevent stress corrosion cracking occurring to the internal surface of a tube by heating a clad steel tube consisting of an internal tube made of alloy steel excellent in corrosion resistance and an external tube made of inexpensive carbon steel to a specific temp. and then subjecting the external tube to rapid cooling by means of high-pressure water, etc.
CONSTITUTION: A clad steel tube is prepared by forming an internal tube of various stainless steels and high alloy steels excellent in corrosion resistance and also forming an external tube of inexpensive carbon steel. The above clad steel tube as a whole is heated up to a solution heat treatment temp. of ≥1000°C and then high-pressure water is sprayed onto the external surface of the above clad steel tube to apply rapid cooling, by which the clad steel tube in which resistance to stress corrosion cracking due to tensile stress established in the internal surface of the tube as well as resistance to intergranular corrosion cracking is improved can be inexpensively manufactured.
