Beschreibung
Zusammenfassung:	The invention relates to the technical field of stainless steel tube processing, in particular to a stainless steel tube smoothness treatment method which comprises the following steps: SA, bright annealing: SA1, putting a stainless steel tube into an annealing furnace; sA2, argon and hydrogen mixed gas is introduced into the annealing furnace, and the gas pressure in annealing reaches the positive pressure of 5 kPa; sA3, the temperature in the annealing furnace is increased to a preset temperature; sA4, keeping the temperature in the annealing furnace; sA5, the temperature in the annealing furnace is reduced to 90-100 DEG C, and the stainless steel pipe is moved out of the annealing furnace; sB, passivating the original color of the stainless steel tube; air pressure fluctuation control is arranged in the SA3 step and the SA4 step, and the air pressure fluctuation control is that argon and hydrogen mixed gas is pumped into or out of the annealing furnace so that the air pressure in the annealing furnace can
