style="text-indent:25px">不銹鋼無縫管屬于鋼管產(chǎn)品中附加值相對還比較高的品種，而此次涉案產(chǎn)品均屬于不銹鋼無縫管中的中高級產(chǎn)品。據(jù)不完全統(tǒng)計(jì)，2010年中國出口至歐盟的不銹鋼無縫管約2萬噸，約占當(dāng)年不銹鋼無縫管出口總量的13%。在我國鋼鐵出口的產(chǎn)品中，鋼管一直是國外反傾銷反補(bǔ)貼調(diào)查的焦點(diǎn)。工貿(mào)部發(fā)布公告，對中國出口的冷軋不銹鋼無縫鋼管發(fā)起反傾銷調(diào)查，在此之前，外貿(mào)商會也表示，將對中國出口的鋼管產(chǎn)品征收每噸743美元(約合人民幣4748元)的反傾銷關(guān)稅，有效期為5年。</p><p style="text-indent:25px">不銹鋼無縫管的制造工藝是熱軋（擠壓無縫鋼管）：圓管坯，加熱，穿孔，三輥斜軋、連軋或擠壓，脫管，定徑（或減徑），冷卻，矯直，水壓試驗(yàn)（或探傷），標(biāo)記，入庫。冷拔（軋）不銹鋼無縫鋼管的軋制方法較熱軋（擠壓無縫鋼管）復(fù)雜。它們的生產(chǎn)工藝流程**步基本相同。不同之處從第四個步驟開始，圓管坯經(jīng)打空后，要打頭，退火。退火后要用專門的酸性液體進(jìn)行酸洗。酸洗后，涂油。然后緊接著是經(jīng)過多道次冷拔（冷軋）再坯管，專門的熱處理。熱處理后，就要被矯直。不銹鋼無縫管加熱工藝的制定應(yīng)綜合考慮熱爐設(shè)備、管坯或鋼管種類、數(shù)量等固有屬性。</p><div

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)測算，汽車用到的不銹鋼無縫管占到整個下游對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。不銹鋼無縫鋼管制管過程中的中間品檢驗(yàn)是控制成品管質(zhì)里的關(guān)鍵，特別是內(nèi)壁表面質(zhì)里，必須重視從源頭抓。上海316不銹鋼無縫方管</p><p style="text-indent:25px">不銹鋼無縫管的鋼管內(nèi)外表面不得有裂縫。山西304大口徑不銹鋼無縫管</p><p style="text-indent:25px">不銹鋼無縫管成型速度快、產(chǎn)量高，可以做成多種多樣的截面形式，以適應(yīng)使用管件的需要；冷軋可以使鋼材產(chǎn)生很大的塑性變形，從而提高了鋼材的屈服點(diǎn)。熱軋可以破壞鋼錠的鑄造組織，細(xì)化鋼材的晶粒，并消除顯微組織的缺陷，從而使鋼材組織密實(shí)，力學(xué)性能得到改善。在使用習(xí)慣上，無縫管因其金屬組織均勻性較好，多用在抗腐蝕性以及承壓耐高溫等性能有要求的項(xiàng)目上，像鍋爐、電站、壓力容器等傳統(tǒng)企業(yè)多青睞無縫鋼管。不銹鋼無縫管認(rèn)可時(shí)不僅需要關(guān)注煉鋼設(shè)備及工藝，更要進(jìn)行延伸至無縫鋼管的試驗(yàn)，通過這樣的認(rèn)可過程來確定鋼坯出廠檢驗(yàn)的檢驗(yàn)項(xiàng)目、取樣數(shù)量和驗(yàn)收標(biāo)準(zhǔn)，特別是規(guī)范和指南中沒有明確但又需要重點(diǎn)關(guān)注的質(zhì)量項(xiàng)目，如低倍和微觀組織的檢測。山西304大口徑不銹鋼無縫管</p></p><br
