style="text-indent:25px">不銹鋼無縫管成品檢驗和試驗的流程主要為表檢，渦探，超探，水壓，氣壓幾道檢測。表檢主要是人工查看鋼管表面有無缺陷，鋼管長度、外壁尺寸是否合格；渦探主要是通過渦流探傷機查看鋼管是否有漏洞；超探主要是利用超聲波探傷機檢查鋼管是否內外開裂；水壓、氣壓是利用水壓機、氣壓機檢測鋼管是否漏水、漏氣，從而確保鋼管完好。檢測合格的不銹鋼無縫管進入成品包裝區(qū)進行包裝。包裝使用的材料有孔帽、塑料袋、蛇皮布、木板、不銹鋼帶等。包裹好的鋼管兩端外表面用小木板襯墊，外用不銹鋼帶系緊，以防止運輸過程中鋼管之間接觸，引起碰撞。包裝好的鋼管進入成品堆放區(qū)。不銹鋼無縫管的檢測及整形必須離線處理。</p><div

style="text-indent:25px">不銹鋼無縫管：以其良好的抗腐蝕性和承壓耐高溫等性能，常用在工程及大型設備上輸送流體管道，也可用作電站等耐高溫、高壓的流體輸送管道。不銹鋼無縫管是一種具有中空截面、周邊沒有接縫的長管鋼材。從上面的工藝流程我們不難看出:其一、該產(chǎn)品的壁厚越厚,它就越具有經(jīng)濟性和實用性,壁厚越薄,它的加工成本就會大幅度的上升;其次、該產(chǎn)品的工藝決定它的局限性，一般無縫鋼管精度低:壁厚不均勻、管內外表光亮度低、定尺成本高，且內外表還有麻點、黑點不易去除;其三、它的檢測及整形必須離線處理。因此，它在高壓、**度、機械結構用材方面體現(xiàn)了它的優(yōu)越性。不銹鋼無縫管組織和成分均勻一致,這對原料尤其重要。重慶316不銹鋼無縫管價格</p><p
