Ø 3.35m/5m/10m 2219 aluminum alloy ring
The tank transition ring is the key load-bearing component and important component of the tank structure of the launch vehicle. The samples on display are taken from the transition rings of the storage tanks of grade Ø 3.35m, Ø 5m and Ø 10m, which are made of 2219 aluminum alloy.
The ring is manufactured by a new method of high temperature multi-directional large flow bloom and fine grain rolling. After heat treatment, the tensile strength of the ring is greatly improved, and the anisotropy is reduced, fully meeting the new requirements of the design index.
