style="text-indent:25px">不銹鋼無縫鋼管普遍用于高壓、低溫和耐腐蝕環(huán)境管系，力學性能、工藝性能和耐腐蝕性是衡量鋼管質量的三項重要指標，也是確保船舶安全航行的重要保證。在實船應用中，某不銹鋼化學品船，在首航后發(fā)現(xiàn)甲板貨物管系存在泄漏，經(jīng)壓力試驗發(fā)現(xiàn)有10余處孔狀泄漏。某乙烯船用貨罐制造過程中，發(fā)現(xiàn)多處罐頭穿艙管內表面質量問題，包括內壁麻點和表面裂紋。那么這些問題如何才能從根本上解決呢?根據(jù)不銹鋼無縫管生產流程，圓鋼鋼坯經(jīng)穿孔、冷拔/冷軋、固溶、校直、酸洗等主要工序制成無縫鋼管，各個制管環(huán)節(jié)相輔相成，特別是對原材料和中間品的質量控制，是確保成品管化學成分、表面質量、力學性能、工藝性能和耐腐蝕性能等指標符合規(guī)范和標準的重要保障。不銹鋼無縫鋼管制管過程中的中間品檢驗是控制成品管質里的關鍵，特別是內壁表面質里，必須重視從源頭抓。</p><div

style="text-indent:25px">304不銹鋼無縫管是一種耐空氣、蒸汽、水等和酸、堿、鹽等腐蝕的鋼管，我們又稱它為不銹耐酸鋼管。不銹鋼無縫管的耐腐蝕性是取決于它本身的含金元素，鉻是一種能夠使不銹鋼具有很好的耐腐蝕性的基本元素，當鋼中含鉻量達到百分之十二左右時，鉻就會和腐蝕介質中的氧發(fā)生作用，在鋼表面形成一層很薄的氧化膜，這樣一來就能夠有效的阻止鋼管進一步的被腐蝕。當然除了鉻外，還有鎳、鉬、鈦、鈮、銅、氮等含金元素。無縫鋼管是除了圓管以外的其他截面形狀的無縫鋼管的總稱。按鋼管截面形狀尺寸的不同又可分為等壁厚異型無縫鋼管（代號為D）、不等壁厚異型無縫鋼管（代號為BD）、變直徑異型無縫鋼管（代號為BJ）。異型無縫鋼管普遍用于各種結構件、工具和機械零部件。和圓管相比，異型管一般都有較大的慣性矩和截面模數(shù)，有較大的抗彎抗扭能力，可以極大減輕結構重量，節(jié)約鋼材。云南無縫不銹鋼管的價格</p></p><br
