style="text-indent:25px">不銹鋼無縫管的制造工藝：軋制無縫管的原料是圓管坯，圓管胚要經(jīng)過切割機的切割加工成長度約為1米的坯料，并經(jīng)傳送帶送到熔爐內(nèi)加熱。鋼坯被送入熔爐內(nèi)加熱，溫度大約為1200攝氏度。燃料為氫氣或乙炔。爐內(nèi)溫度控制是關(guān)鍵性的問題.圓管坯出爐后要經(jīng)過壓力穿孔機進行穿空。一般較常見的穿孔機是錐形輥穿孔機，這種穿孔機生產(chǎn)效率高，產(chǎn)品質(zhì)量好，穿孔擴徑量大，可穿多種鋼種。穿孔后，圓管坯就先后被三輥斜軋、連軋或擠壓。擠壓后要脫管定徑。定徑機通過錐形鉆頭高速旋轉(zhuǎn)入鋼胚打孔，形成鋼管。鋼管內(nèi)徑由定徑機鉆頭的外徑長度來確定。鋼管經(jīng)定徑后，進入冷卻塔中，通過噴水冷卻，鋼管經(jīng)冷卻后，就要被矯直。鋼管經(jīng)矯直后由傳送帶送至金屬探傷機(或水壓實驗)進行內(nèi)部探傷。若鋼管內(nèi)部有裂紋，氣泡等問題，將被探測出。鋼管質(zhì)檢后還要通過嚴格的手工挑選。鋼管質(zhì)檢后，用油漆噴上編號、規(guī)格、生產(chǎn)批號等。并由吊車吊入倉庫中。不銹鋼無縫管工件的原始狀態(tài)、加工方式須與工藝文件的規(guī)定相符合。</p><div

style="text-indent:25px">不銹鋼無縫管是除了圓管以外的其他截面形狀的無縫鋼管的總稱。按鋼管截面形狀尺寸的不同又可分為等壁厚異型無縫鋼管、不等壁厚異型無縫鋼管、變直徑異型無縫鋼管。異型無縫鋼管普遍用于各種結(jié)構(gòu)件、工具和機械零部件。和圓管相比，異型管一般都有較大的慣性矩和截面模數(shù)，有較大的抗彎抗扭能力，可以極大減輕結(jié)構(gòu)重量，節(jié)約鋼材。流體輸送用不銹鋼無縫鋼管是用于輸送水、油、氣等流體的一般無縫鋼管，通常是用不銹鋼制成的熱軋（擠、擴）和冷拔（軋）無縫鋼管。不銹鋼無縫管擁有的各種無縫鋼管熱軋機組300多套，年產(chǎn)能3000萬t以上。重慶無縫304不銹鋼管</p><p
