This invention provides a method for producing small-diameter, thick-walled near-α-type titanium alloy tubing and its application. This method, through the use of cladding and heated rolling, increases the deformation per rolling pass, reduces the number of rolling passes, and results in a finer microstructure and better mechanical properties in the heated-rolled tubing. Simultaneously, the composite material composed of the cladding layer and silica aerogel effectively prevents the alloy rod from contacting air, avoiding further surface oxidation and reducing the thickness of the oxide layer on the rod surface. Furthermore, the composite material forms a "thermal insulation layer" on the surface of the alloy rod, preventing large temperature differences between the surface and core during heated rolling, thus ensuring better microstructure uniformity and surface quality. In this invention, the cladding process expands the selection of heating furnaces and reduces equipment requirements.
