消防給水系統(tǒng)是水滅火系統(tǒng)的心臟，只有心臟安全可靠，水滅火系統(tǒng)才能可靠。而消防管就好像血管，而我們消防設(shè)計中用的**多的管材便是鍍鋅鋼管，鍍鋅鋼管即安全可靠性，又經(jīng)濟合理。由于消防管道的安裝涉及我我們的人身和財產(chǎn)安全，所以消防管的安裝尤為重要，下面我們一起來學(xué)習一下消防鍍鋅鋼管施工標準和質(zhì)量控制措施。工程師在進行管道安裝的檢查一、重點控制項目1.施工前應(yīng)進行管線綜合和深化設(shè)計，管道布局合理，順直明快，減少占用空間，且美觀大方管線布局合理，排列有序，層次分明，橫平豎直管線布局合理，排列有序，層次分明，橫平豎直2.管道管徑小于DN100時采用絲扣連接，等于大于DN100時采用卡箍或者法蘭連接3.絲扣連接采用麻根和生料帶密封，禁止采用液態(tài)生料帶；絲扣外露2至3扣，并***麻頭，外露絲扣涂刷防銹漆4.管道切割時管口應(yīng)平整，卡箍溝槽應(yīng)用**機械滾槽5.安裝必須遵循大口徑總管—立管—小口徑支管的安裝順序原則。安裝過程中不可跳裝或分段裝，必須按順序連續(xù)安裝，以免出現(xiàn)段與段之間連接困難影響安裝質(zhì)量安裝要規(guī)范6.鍍鋅鋼管原則上不得采用焊接連接方式，如確實需要時。切口處若有毛刺，應(yīng)用砂紙、銼刀或砂輪機打磨。建議使用套絲機的管刀進行斷管。</p><div

304不銹鋼彎頭是一種提高不銹鋼強度、耐腐蝕性和奧氏體穩(wěn)定性的有效元素。**近對含氮奧氏體不銹鋼、雙相不銹鋼和馬氏體不銹鋼進行了許多研究。日本大同特殊鋼公司研究開發(fā)部的科研人員用高壓感應(yīng)熔煉法生產(chǎn)含量為、。在各種熱處理制度下對試制鋼的硬度和耐腐蝕性進行了研究，獲得的結(jié)果如下：(1)經(jīng)零下處理硬化后，這些鋼的**硬度隨碳含量的增加而增加，而它們的殘余奧氏體體積分數(shù)隨氮含量的增加而增加。(2)在回火過程中，這些鋼在723-773K時都顯示明顯的二次硬化，并且**硬度隨氮含量的增加而增加。723K回火后馬氏體硬度的變化隨基體中氮的質(zhì)量分數(shù)的增加而增加。淬火狀態(tài)材料的固溶體中的氮含量。(3)回火后這些鋼的耐腐蝕性隨回火溫度的增加而降低。含。不銹鋼牌號分組沉淀硬化型不銹鋼。具有有很好的成形性能和良好的焊接性，可作為超**度的材料在核工業(yè)、航空和航天工業(yè)中應(yīng)用。按成分可分為Cr系（SUS400）、Cr－Ni系（SUS300）、Cr－Mn－Ni（SUS200）及析出硬化系（SUS600）。304—即18/8不銹鋼。GB牌號為0Cr18Ni9。309—較之304有更好的耐溫性。316—繼304之後，第二個得到**廣泛應(yīng)用的鋼種，主要用于食品工業(yè)和外科手術(shù)器材。滁州鍍鋅鋼管價格</p><p
