style="text-indent:25px">在施工現(xiàn)場,由于施工場地、空間和施工工具的限制，施工人員經(jīng)常利用不銹鋼無縫管材的塑性而不按施工規(guī)范強(qiáng)行施工，所以，有必要考慮管材與管件連接處的扭曲因素。由于較輕，可輕松搬運(yùn)和施工并降低成本。薄壁不銹鋼管由于耐腐蝕性和機(jī)械性能超群，只需要鍍鋅鋼管厚度的約三分之一即可。因此管材的重量極大變輕，成本也隨之降低，使搬運(yùn)更加輕松，安裝更加方便。不銹鋼無縫管簡稱無縫管。無縫不銹鋼管表面粗糙，長度無定尺。無縫不銹鋼管用于：鍋爐，中央空調(diào)，鋼結(jié)構(gòu)，機(jī)械加工，管道燃?xì)?，消防等等。四川無縫管316不銹鋼不銹鋼無縫管在滲氮前要做好什么準(zhǔn)備工作呢？</p><div

style="text-indent:25px">不銹鋼無縫管成品檢驗(yàn)和試驗(yàn)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(jī)查看鋼管是否有漏洞；超探主要是利用超聲波探傷機(jī)檢查鋼管是否內(nèi)外開裂；水壓、氣壓是利用水壓機(jī)、氣壓機(jī)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(jìn)入成品包裝區(qū)進(jìn)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(yùn)輸過程中鋼管之間接觸，引起碰撞。包裝好的鋼管進(jìn)入成品堆放區(qū)。</p><p
