考登鋼管主要用於(yú):高含硫煙(yān)氣中的(de)省煤氣、空氣(qì)預熱(rè)器、熱交換器和(hé)蒸發器,用於抵禦(yù)含硫煙氣的結露腐蝕。具有卓越的耐(nài)硫離子,耐(nài)鹽酸及其(qí)他酸性腐蝕的能力。考登鋼(gāng)管為(wéi)高效、經濟、成熟的傳(chuán)熱元件,已經大量使用在各(gè)種(zhǒng)鍋爐的空氣預熱器產品中。螺旋槽(cáo)管利用藕節狀內壁和螺旋槽導流,強製擾動(dòng)管內工質,從而提高傳熱(rè)效率。螺旋槽管的傳熱係(xì)數一般可(kě)以達到同徑(jìng)光管的1.25倍,使用螺旋槽管可以提高(gāo)換熱設備的效率,減少鋼管的用量,縮小換熱設備占用的空間,具有良好的經濟性和可靠(kào)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.

考登鋼又名Corten鋼,分兩大類(lèi):Corten A、CortenB,是美國Cu-P係列鋼的代表鋼種,屬(shǔ)於低(dī)合金高強耐(nài)大氣腐蝕結構(gòu)鋼,國內叫做耐候鋼。 考登鋼管主要用於:高含硫煙氣中的省煤氣、空氣預熱器、熱交換器(qì)和蒸發器(qì),用於抵禦含硫煙(yān)氣的結露(lù)腐蝕。具有卓(zhuó)越的耐硫(liú)離(lí)子,耐鹽酸及其他酸性腐蝕的能力。
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(jiē)鋼管(guǎn)也稱(chēng)焊管,是用鋼板或帶鋼(gāng)經(jīng)過卷曲成型後(hòu)焊接製成(chéng)的(de)鋼管。焊接鋼管生產工藝簡單,生產(chǎn)效率高,品種規格多,設(shè)備資少,但(dàn)一般強度(dù)低於(yú)無縫鋼(gāng)管。其(qí)中流體輸送用不鏽鋼焊接(jiē)鋼管主要用於輸送低壓腐蝕性介質。代表材質為0Cr13、0Cr19Ni9、00Cr19Ni11、00Cr17、0Cr18Ni11Nb、0017Cr17Ni14Mo2等(děng)。
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.
