考登（dēng）鋼管主要用於：高含（hán）硫煙氣（qì）中的省煤氣、空氣預（yù）熱器、熱（rè）交換器和蒸發器，用於（yú）抵禦含硫（liú）煙氣的（de）結露腐蝕。具有卓越的耐硫離子，耐鹽（yán）酸（suān）及其他酸性腐蝕的能力。考登鋼管為高（gāo）效、經濟、成熟的傳熱元件，已經大量使用在各種鍋爐的空氣（qì）預熱器產品中。螺旋槽管（guǎn）利用藕節狀（zhuàng）內壁和螺旋槽導（dǎo）流，強製擾動管（guǎn）內工質（zhì），從而提高（gāo）傳熱效率。螺旋槽管的傳熱係數一般可以達（dá）到同徑光管的1.25倍，使用螺旋槽管可以提高換熱設備的效率，減少鋼管的用（yòng）量，縮小換（huàn）熱設備占用的空間，具有良（liáng）好的經濟（jì）性和可靠性。
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 with 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 reliability.

考（kǎo）登鋼（gāng）又名Corten鋼，分兩（liǎng）大類：Corten A、CortenB，是美國Cu-P係列鋼的代表鋼種，屬於低合金高強耐大氣腐蝕（shí）結構鋼，國內叫做耐候鋼。 考登鋼管主（zhǔ）要用（yòng）於：高含硫煙氣（qì）中的省煤氣、空氣預熱器、熱交換器和蒸發器，用於抵禦含（hán）硫煙氣的結露腐蝕。具有卓越的耐硫離子，耐鹽酸及其他（tā）酸性腐蝕的能力。
Corten steel, also known as Corten steel, can be divided into two categories: Corten A and CortenB. Corten B is the representative steel of U.S. Cu-P series steel. It belongs to low-alloy, high-strength and atmospheric corrosion resistant structural steel. It is 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.
焊接鋼管也稱焊管，是用鋼板或帶鋼經過卷曲成型後焊（hàn）接製成的鋼管。焊接鋼管生產工藝（yì）簡單，生產（chǎn）效率高，品種規格多，設備資少，但一般強度低於（yú）無縫鋼管。其中流體輸送用不鏽鋼焊接鋼管主要用於（yú）輸送低壓腐蝕性介質。代表材質為0Cr13、0Cr19Ni9、00Cr19Ni11、00Cr17、0Cr18Ni11Nb、0017Cr17Ni14Mo2等。
Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip after coiling and forming. Welded steel pipe has the advantages of simple production process, high production efficiency, many varieties and specifications and less equipment, but its general strength is lower than that of seamless steel pipe. Among them, stainless steel welded pipe for fluid transportation is mainly used to transport low-pressure corrosive media. The representative materials are 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, etc.
