Abstract (en)

[origin: WO2004061147A1] An inlet pipe 6 and an outlet pipe 7 for use in condensers are made from an alloy containing 0.90 to 1.50 mass % of Mn, and the balance Al and inevitable impurities. The inlet pipe 6 and the outlet pipe have an electrical conductivity of 30 to 43% IACS. The inlet pipe 6 and an outlet pipe 7 are each produced from a pipe blank made from an alloy containing 0.90 to 1.50 mass % of Mn, and the balance Al and inevitable impurities, by holding the pipe blank heated at 550 to 600 C in the atmosphere or in an inert gas atmosphere for 10 to 600 minutes and thereafter cooling the pipe blank. The inlet pipe 6 and the outlet pipe 7 can be produced easily at a low cost and have satisfactory resistance to pitting corrosion.
