考登無縫（féng）鋼管重（chóng）點用於：高含硫煙霧正（zhèng）當中省瓦斯、大氣傳熱器、熱貿易器和作為器，可用於起義含硫煙霧的結露破壞。具備卓越的耐硫（liú）離子（zǐ）化，耐檸檬酸以及其他堿性破壞的實際能力。考登無縫鋼管為效率更高、經濟領域、較為完善的熱傳導部（bù）件，目前已經很多采用在（zài）多種（zhǒng）火爐的大氣傳熱器產品中。螺旋（xuán）形槽管使用（yòng）藕節狀內壁和螺旋形槽導流（liú），必須執行波動缸管工質（zhì），進（jìn）而使原有水平上升熱傳導（dǎo）工作效率。螺旋形槽管的熱傳導膨脹係數通常能夠實現（xiàn）同徑光管的1.25倍，采用螺旋形槽管能夠使原有水平上升換（huàn）熱（rè）設備的工作效率，進一步降低無縫鋼管的有（yǒu）關用量，減少換熱設備占領的宇宙空間，具備較好的經濟領域性和值得信賴性。
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）登鋼有關又名Corten鋼，分兩大類：Corten A、CortenB，是美國（guó）Cu-P多個係列鋼的表示人種，進行所在低（dī）鋁合金高（gāo）強耐空氣破壞整體結（jié）構鋼，中國大陸稱（chēng）為耐候鋼。 考登無縫鋼管重點用於：高含硫煙霧（wù）正當中省瓦斯、大氣傳熱器、熱貿易器和作為器，可用於（yú）起義含硫煙霧的結露破壞。具備卓（zhuó）越（yuè）的耐硫離（lí）子化，耐（nài）檸檬酸以及其他堿性破壞的實際能力。
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.
銲接無（wú）縫鋼管也（yě）稱（chēng）焊管，是（shì）用謄寫鋼版或帶鋼經曆卷起有（yǒu）關成（chéng）型後銲（hàn）接釀（niàng）成的無縫鋼管。銲接無縫鋼管製造工藝更為簡便，製造效率高，栽培品種規（guī）格多，設備資少，但通常極限抗拉強（qiáng）度不可企及無縫無縫鋼管。在這當中半流體輸氣用不鏽（xiù）鋼銲接無縫鋼（gāng）管（guǎn）重點用於輸氣低氣壓破（pò）壞性電（diàn）介質。表示材料為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.
