不銹鋼管是一種經(jīng)濟(jì)的斷面鋼材，是鋼鐵工業(yè)中的一項(xiàng)重要產(chǎn)品，可***用于生活裝飾和工業(yè)，市面上很多人用于制作樓梯扶手、護(hù)窗、欄桿、家具等。常見的有201和304兩種材質(zhì)。占全部鋼材總量的8%一16%左右，它在國(guó)民經(jīng)濟(jì)中的應(yīng)用范圍極為***。不銹鋼按生產(chǎn)方式分為無(wú)縫管和焊管兩大類，那么兩者有什么區(qū)別？ </p> <p> <span style="display:none;"></span> </p> <p> <br /> </p> <p> 1、工藝的區(qū)別 </p> <p> <br /> </p> <p> 不銹鋼無(wú)縫管是一種具有中空截面、周邊沒有接縫的長(zhǎng)條鋼材。該產(chǎn)品的壁厚越厚，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；該產(chǎn)品的工藝決定它的局限性能，采用的是圓管坯作為原料進(jìn)行穿孔，通過(guò)冷軋、冷拔或者熱擠壓的生產(chǎn)工藝制作而成，管上沒有焊接點(diǎn)。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；它的檢測(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。 </p> <p> <br /> </p> <p> <br /> </p><p> 304不銹鋼無(wú)縫管的加工工藝以及工藝特點(diǎn) </p> <p> 304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;它的檢測(cè)及整形必須離線處理。因此304不銹鋼無(wú)縫管在高壓、**度、機(jī)械結(jié)構(gòu)用材方面體現(xiàn)了它的優(yōu)越性。304不銹鋼無(wú)縫鋼管的合理加工非常重要，那么在加工過(guò)程中，需要做哪些細(xì)節(jié)呢？普通不銹鋼管通過(guò)特殊的螺紋加工設(shè)備(自行開發(fā))以一定的螺距進(jìn)行旋轉(zhuǎn)擠壓，在鋼管的內(nèi)、外表面形成一定螺距的螺旋槽，使鋼管內(nèi)外壁的換熱面積相應(yīng)增加。使用時(shí)，流體傳導(dǎo)介質(zhì)在管腔內(nèi)形成螺旋渦流，通過(guò)管壁快速傳導(dǎo)熱量，使換熱器的總熱效率提高1.5-2倍。因此，通過(guò)合理的加工，不銹鋼無(wú)縫管的性能可以說(shuō)是非常突出，是人們的一個(gè)很好的選擇。用做裝飾管、制品管、道具管時(shí)，一般要求有良好的表面效果，通常選用不銹鋼焊管。</p><div
