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（míng）Corten鋼，分兩大類：Corten A、CortenB，是美國Cu-P係列鋼的代表鋼種（zhǒng），屬於低合金高強耐大（dà）氣腐（fǔ）蝕結構鋼，國內叫做耐（nài）候鋼。 考登鋼管主要用（yòng）於：高含硫煙氣中的省（shěng）煤氣、空氣預熱器、熱交（jiāo）換器和蒸發器，用於抵禦含硫煙氣的結露腐蝕。具有卓越的耐硫離子，耐鹽酸及其（qí）他（tā）酸性腐蝕的（de）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（yòng）鋼板或帶鋼經過卷（juàn）曲成型後焊接製成的鋼管。焊接鋼管生產工藝簡單，生產效率高，品（pǐn）種規格（gé）多，設備資少，但一般強度低於無縫鋼管（guǎn）。其中流體輸送用不鏽鋼焊接鋼管主要用於輸送低壓腐蝕性介質。代（dài）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.
