Corten steel pipe, also known as Corten steel, can be divided into two categories: Corten A and CortenB, which are representative steels of U.S. copper-P series steel, belong to low-alloy, high-strength, atmospheric corrosion resistant structural steel, and are called weathering steel in China. Cauden steel pipe is mainly used for saving gas, air preheater, heat exchanger and evaporator in high sulfur flue gas, to resist condensation corrosion of sulfur flue gas. Excellent sulfur ion resistance, hydrochloric acid resistance and other acid corrosion resistance. Spiral grooved tube is an efficient, economical and mature heat transfer element, which has been widely used in various air preheater products of boilers. Spirally grooved tube utilizes the inner wall of lotus root and spiral groove to guide flow, forcing disturbance of working fluid in the tube, thereby improving heat transfer efficiency. The heat transfer coefficient of spirally grooved tubes can generally reach 1.25 times of that of light tubes of the same diameter. The use of spirally grooved tubes can improve the efficiency of heat exchangers, reduce the consumption of steel tubes, and reduce the space occupied by heat exchangers. It has good economy and reliable execution standards. 考（kǎo）登鋼管和ND鋼管成品執（zhí）行標準：
