nd钢管与考登钢管有什么区别?价格一样吗?

考登钢又名Corten钢,分两大类:Corten A、CortenB,是美国Cu-P系列钢的代表钢种,属于低合金高强耐大气腐蚀结构钢,国内叫做耐候钢。考登钢管主要用于:高含硫烟气中的省煤气、空气预热器、热交换器和蒸发器,用于抵御含硫烟气的结露腐蚀。具有卓越的耐硫离子,耐盐酸及其他酸性腐蚀的能力。螺旋槽管为高效、经济、成熟的传热元件,已经大量使用在各种锅炉的空气预热器产品中。螺旋槽管利用藕节状内壁和螺旋槽导流,强制扰动管内工质,从而提高传热效率。螺旋槽管的传热系数一般可以达到同径光管的1.25倍,使用螺旋槽管可以提高换热设备的效率,减少钢管的用量,缩小换热设备占用的空间,具有良好的经济性和可靠性执行标准
Corten steel, also known as Corten steel, can be divided into two categories: Corten A and CortenB, which are representative steels of U.S. Cu-P series steel. They belong to low-alloy, high-strength, atmospheric corrosion resistant structural steels 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. 考登钢管和ND钢管成品执行标准:
