Manufacturing method of spiral corrugated pipe made of aluminum alloy material and aluminum coiled material

The invention provides a manufacturing method of a spiral corrugated pipe made of aluminum alloy and an aluminum coiled material for installing the spiral corrugated pipe made of the aluminum alloy, and the manufacturing method comprises the following steps: a) taking a recycled low-carbon aluminum alloy strip as a raw material which is recycled aluminum, and performing melting, casting, hot rolling, cold rolling, annealing, straightening and strip cutting on the recycled aluminum to obtain the aluminum alloy coiled material; b) uncoiling the aluminum alloy coiled material on an uncoiling machine, and performing multi-stage continuous deformation through a plurality of compression roller groups to form an aluminum alloy strip with an n-shaped section; c) spinning the aluminum alloy strip with the n-shaped section through a plurality of groups of spiral pressing rollers, and gradually forming a spiral corrugated pipe on a cylindrical rotary drum through spinning the aluminum alloy strip with the n-shaped secti
