The Corrugated Tube Heat Exchanger is mainly used under the condition of heat transfer with heating and cooling. The material of the corrugated tubes can be thin-wall stainless steel, copper and carbon steel. The inner pipe wall can change the fluid flow state, and the outer pipe wall can increase the heat transfer area and impulsive motion so as to achieve the purpose of heat transfer on the two sides. The heat transfer coefficient of Corrugated Tube Heat Exchanger is 1.2 to 2.4 times of that of normal shell-and-tube heat exchanger. Because  of the good compensation of the the special wave-shaped section the corrugated tubes, the tubesheet will not fail with cracks induced by over pulling stress.
