style="text-indent:25px">不銹鋼無縫管在尿素-氨基甲酸鹽溶液中具有良好的耐蝕性，在氯化物環(huán)境中擁有很高的抗應(yīng)力腐蝕開裂能力。同時(shí)，該雙相不銹鋼機(jī)械性能優(yōu)異，可應(yīng)用于安全性要求較高的廠房建設(shè)。用到不銹鋼無縫管的主要是排氣系統(tǒng)，占汽車不銹鋼總用量的1/2以上，80%為鐵素體不銹鋼無縫管。汽車發(fā)動(dòng)機(jī)產(chǎn)生的廢氣通過廢氣進(jìn)氣管、前管、軟管、轉(zhuǎn)換器、中心管從消聲器中流出。排氣系統(tǒng)常用鋼種有409L，436L等。汽車消聲器主要使用不銹鋼無縫管。據(jù)測(cè)算，汽車用到的不銹鋼無縫管占到整個(gè)下游對(duì)不銹鋼管用量的大約1.5%，而不銹鋼無縫管和焊管的使用比例大約2:1。不銹鋼無縫管的加工工藝是什么呢？</p><div

)，遇冷凝水，形成硫酸、硝酸、醋酸液點(diǎn)，引起化學(xué)腐蝕。不銹鋼無縫管表面存積著含有其他金屬元素的粉塵或異類金屬顆粒的附著物，在潮濕的空氣中，附著物與不銹鋼無縫管間的冷凝水，將二者連成一個(gè) 微電池，引發(fā)了電化學(xué)反應(yīng)，保護(hù)膜受到破壞，稱之謂電化學(xué)腐蝕。河北無縫不銹鋼管國標(biāo)</p></p><br
