Zusammenfassung:	A Ni-based alloy pipe, the chemical composition of the base metal of which is, in mass%, C: not more than 0.15%, Si: not more than 1.0%, Mn: not more than 2.0%, P: not more than 0.030%, S: not more than 0.030%, Cr: 10.0-40.0%, Ni: 50.0-80.0%, Ti: not more than 0.50%, Cu: not more than 0.60%, Al: not more than 0.20%, N: not more than 0.20%, with the remainder being Fe and impurities, the Ni-based alloy pipe being provided with a low Cr composite oxide film with a thickness of not more than 25 nm on at least the inner surface of the base metal. The Al, Ni, Si, Ti and Cr contents in said film satisfy [at% Al/at% Cr
