Abstract

PURPOSE: To curtail cost as well as raise corrosion resistance by using a two-phase stainless steel time for the part of expanded pipe and also using a ferrite stainless steel pipe for the remaining part.
CONSTITUTION: In the heating pipe structure of a chemical apparatus requiring stress corrosion cracking resistance, corrosion resistance, processability, and weldability, a two-phase alloy steel having a 18Cr-5Ni-3Mo alloying component is used for the expanded part 4 inserted into the piping plate 1, and also a ferrite stainless steel having a 26Cr-1Mo alloying component is used for the part 5 requiring the stress corrosion crack resistance and corrosion resistance alone by means of the welding 6. Thus, the heating pipe 2 of expanded part inserted into the piping plate 1 assures an exact and close-contact expansion of pipe because of its excellent processability and also the heating pipe part 5 can exhibit sufficiently high corrosion resistance and stress corrosion crack resistance.
