style="text-indent:25px">不銹鋼無縫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。按生產(chǎn)方法不同可分為熱軋管、冷軋管、冷拔管、擠壓管等。熱軋不銹鋼無縫管一般在自動軋管機(jī)組上生產(chǎn)。實心管坯經(jīng)檢查并去除表面缺陷，截成所需長度，在管坯穿孔端端面上定心，然后送往加熱爐加熱，在穿孔機(jī)上穿孔。在穿孔同時不斷旋轉(zhuǎn)和前進(jìn)，在軋輥和頂頭的作用下，管坯內(nèi)部逐漸形成空腔，稱毛管。再送至自動軋管機(jī)上繼續(xù)軋制。經(jīng)均整機(jī)均整壁厚，經(jīng)定徑機(jī)定徑，達(dá)到規(guī)格要求。利用連續(xù)式軋管機(jī)組生產(chǎn)熱軋無縫鋼管是較先進(jìn)的方法。不銹鋼無縫管可任意定尺，尺寸規(guī)格豐富，在大口徑和薄壁方面優(yōu)勢尤為突出。安徽304無縫不銹鋼管廠家</p><p style="text-indent:25px">不銹鋼無縫管中的“黑線”是如何造成的呢？安徽304無縫不銹鋼管廠家</p><p style="text-indent:25px">不銹鋼無縫管都要進(jìn)行液壓試驗來檢驗其耐壓能力和質(zhì)量，在規(guī)定的壓力下不發(fā)生泄漏、浸濕或膨脹為合格，有些鋼管還要根據(jù)標(biāo)準(zhǔn)或需方要求進(jìn)行卷邊試驗、擴(kuò)口試驗、壓扁試驗。無縫不銹鋼管也稱不銹鋼無縫管，是用鋼錠或?qū)嵭墓芘鹘?jīng)穿孔制成毛管，然后經(jīng)熱軋、冷軋或冷撥制成。無縫鋼管的規(guī)格用外徑壁厚毫米數(shù)表示。隨著我國開放政策的實施，國民經(jīng)濟(jì)獲得快速增長，城鎮(zhèn)住宅、公共建筑和旅游設(shè)施大量興建，對熱水供應(yīng)和生活用水供給提出了新的要求。特別是水質(zhì)問題，人們越來越重視，要求也不斷提高。鍍鋅鋼管這一常用管材因其易腐蝕性，在國家相關(guān)政策的影響下，將逐漸退出歷史舞臺，塑料管、復(fù)合管及銅管成了管道系統(tǒng)的常用管材。但在許多情況下，不銹鋼管更有優(yōu)越性，特別是壁厚*為0.6~1.2mm的薄壁不銹鋼管在優(yōu)越飲用水系統(tǒng)、熱水系統(tǒng)及將安全、衛(wèi)生放在**的給水系統(tǒng)，具有安全可靠、衛(wèi)生環(huán)保、經(jīng)濟(jì)適用等特點。已被國內(nèi)外工程實踐證明是給水系統(tǒng)綜合性能比較好的、新型、節(jié)能和環(huán)保型的管材之一，也是一種很有競爭力的給水管材，必將對改善水質(zhì)、提高人們生活水平發(fā)揮無可比擬的作用。安徽304無縫不銹鋼管廠家</p></p><br
