The compared experiment with smooth steel tube shows that heat transfer of spiral corrugated steel tube is 12.9 %～65.5% higher than that of smooth steel tube. The spiral corrugated steel tube is applied in the vertical ammonia condenser of a factory, and the coefficient increase by 32.6%～57% over that of smooth steel tube.
