| description | The invention discloses a manufacturing method of a super-long corrosion-resistant aluminum alloy seamless tube. A formula of the aluminum alloy comprises the following components in percentage by weight: less than 0.05% of Si, less than 0.15% of Fe, less than 0.002% of Cu, less than 0.1% of Mn, 2.4-2.8% of Mg, less than 0.17% of Cr, less than 0.005% of Zn, less than 0.007% of Pb, less than 0.02% of single other impurities, less than 0.10% of total impurities and the balance Al. As harmful trace elements such as Si, Cu, Zn and Pb are strictly controlled, the corrosion resistance of the material is improved, the surface corrosion rate of the produced aluminum alloy pipe in seawater is only 0.0052 mm/year or below.
