The invention relates to a high-temperature alloy tubing processing technique, the operating steps: 1) perform solution treatment under 1050-1150 deg.C, soaking: 0.5-1 hour, water-cooling and central drilling on stick material to make spiral pressure blank; 2) make spiral pressure on the blank for 4-6 times, during the spiral pressure, make vacuum solution treatment under 1050-1150 deg.C for 0.5-1 hour; 3) perform vacuum anneal treatment under 1050-1150 deg.C, soaking: 0.5-1 hour, and air-tempering on the spiral pressure tubing to make the tubing as cold-rolling tube blank; 4) roll the coal-rolling tube blank to make coal-rolled tube; 5) perform vacuum solution treatment, and air-tempering on the coal-rolled tube under 1050-1150 deg.C for 0.5-1 hour to make finished product by coal rolling.
