style="text-indent:25px">不銹鋼無(wú)縫管的制造工藝是熱軋（擠壓無(wú)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(kù)。冷拔（軋）不銹鋼無(wú)縫鋼管的軋制方法較熱軋（擠壓無(wú)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(gè)步驟開(kāi)始，圓管坯經(jīng)打空后，要打頭，退火。退火后要用專(zhuān)門(mén)的酸性液體進(jìn)行酸洗。酸洗后，涂油。然后緊接著是經(jīng)過(guò)多道次冷拔（冷軋）再坯管，專(zhuān)門(mén)的熱處理。熱處理后，就要被矯直。不銹鋼無(wú)縫管焊接的方式不同可分成直縫不銹鋼焊管，螺旋不銹鋼焊管。山西304不銹鋼無(wú)縫管廠家</p><p

style="text-indent:25px">不銹鋼無(wú)縫管是一種中空的長(zhǎng)管圓形鋼材，普遍用于石油、化工、醫(yī)療、食品、輕工、機(jī)械儀表等工業(yè)輸送管道以及機(jī)械結(jié)構(gòu)部件等。另外，在折彎、抗扭強(qiáng)度相同時(shí)，重量較輕，所以也普遍用于制造機(jī)械零件和工程結(jié)構(gòu)。也常用作生產(chǎn)各種常規(guī)武器、炮彈等。不銹鋼無(wú)縫管的壁厚越厚，它就越具有經(jīng)濟(jì)性和實(shí)用性，壁厚越薄，它的加工成本就會(huì)大幅度的上升；不銹鋼無(wú)縫管的工藝決定它的局限性能，一般無(wú)縫鋼管精度低：壁厚不均勻、管內(nèi)外表光亮度低、定尺成本高，且內(nèi)外表還有麻點(diǎn)、黑點(diǎn)不易去除；不銹鋼無(wú)縫管的檢測(cè)及整形必須離線處理。因此它在高壓、**度、機(jī)械結(jié)構(gòu)用材方面體現(xiàn)了它的優(yōu)越性。山西不銹鋼管道無(wú)縫鋼管</p></p><br
