Abstract: A method for preparing a high-performance difficult-to-deform metal precision seamless pipe includes steps of performing a heat treatment; drilling; externally grinding; internally grinding; straightening; performing four-roller warm-rolling; performing warm-drawing to reduce a diameter; performing warm-expansion to reduce a wall thickness and increase the diameter; performing precise cold-rolling; degreasing; brightening; performing surface grinding; cleaning dust; detecting flaws; testing metal structure performance; and sizing and packaging. By cycling the warm-drawing, the warm-expansion, and the precision cold-rolling, key indicators such as product dimensional accuracy, surface quality, material properties, and crystal grain size can be collaboratively controlled, to achieve higher accuracy, better performance, and more outstanding extreme specifications. Product requirements of different hard-to-deform metal materials and different product specifications can be satisfied, to flexibly prepare metal pipe products with different material characteristics, which greatly improves production efficiency and effectively reduces production costs.
