鍍鋅方管鍍鋅的作用是什么？ </p> <p> 鍍鋅方管鍍鋅可增加方管的抗腐蝕能力，延長(zhǎng)使用壽命。 </p> <p> 鍍鋅管的用途很廣，除作輸水、煤氣、油等一般低壓力流體的管線管外，還用作石油工業(yè)特別是海洋油田的油井管、輸油管，化工焦化設(shè)備的油加熱器、冷凝冷卻器、煤餾洗油交換器用管，以及棧橋管樁、礦山坑道的支撐架用管等。為提高的耐腐蝕性能，對(duì)一般方管（黑管）進(jìn)行鍍鋅。鍍鋅方管分熱鍍鋅和電鋼鋅兩種，熱鍍鋅鍍鋅層厚，電鍍鋅成本低，所以有了鍍鋅方管。熱鍍鋅方管的產(chǎn)品質(zhì)量該怎樣鑒別？</p><div

style="text-indent:25px">冷鍍鋅方管：冷鍍鋅管就是電鍍鋅，鍍鋅量很少，只有10-50g/m2，其本身的耐腐蝕性比熱鍍鋅管相差很多。正規(guī)的鍍鋅管生產(chǎn)廠家，為了保證質(zhì)量，大多不采用電鍍鋅(冷鍍)。只有那些規(guī)模小、設(shè)備陳舊的小企業(yè)采用電鍍鋅，當(dāng)然他們的價(jià)格也相對(duì)便宜一些。目前建設(shè)部已正式下文，淘汰技術(shù)落后的冷鍍鋅管，今后不準(zhǔn)用冷鍍鋅管作水、煤氣管。冷鍍鋅方管鍍鋅層是電鍍層，鋅層與方管基體**分層。鋅層較薄，鋅層簡(jiǎn)單附著在方管基體上，容易脫落。故其耐腐蝕性能差。在新建住宅中，禁止使用冷鍍鋅方管作為給水管。熱鍍鋅方管報(bào)價(jià)，云南贛僑鋼材廠家供應(yīng)。昆明經(jīng)開區(qū)Q235熱鍍鋅方管廠</p><p style="text-indent:25px">鍍鋅方管鍍鋅的作用是什么？昆明經(jīng)開區(qū)Q235熱鍍鋅方管廠</p><p> 檢測(cè)熱熱鍍鋅方管表面缺陷的方法： </p> <p> 方管表面缺陷的檢測(cè)方法： </p> <p> 電渦流檢測(cè)：電渦流檢測(cè)有多種形式，常用的有常規(guī)渦流檢測(cè)、遠(yuǎn)場(chǎng)渦流檢測(cè)、多頻渦流檢測(cè)和脈沖渦流檢測(cè)等，利用電渦流傳感器對(duì)金屬進(jìn)行感應(yīng)，方管表面不同缺陷類型和形狀將產(chǎn)生不同類型的信號(hào)。其優(yōu)點(diǎn)是檢測(cè)精度高、探測(cè)靈敏度高，檢測(cè)速度快，能檢測(cè)待檢測(cè)管材的表面及亞表面，且不受待檢測(cè)方管表面油污等雜質(zhì)的影響。缺點(diǎn)是易將非缺陷結(jié)構(gòu)判定為缺陷，誤檢率較高，檢測(cè)分辨率不容易調(diào)整。 </p> <p> 超聲波檢測(cè)：利用超聲波進(jìn)入物體遇到缺陷時(shí)，一部分聲波會(huì)產(chǎn)生反射，發(fā)射和可對(duì)反射波進(jìn)行分析，就能異常精確地測(cè)出缺陷來。超聲波檢測(cè)常用于鍛件檢測(cè)，檢測(cè)探傷靈敏度高，但是不易檢查形狀復(fù)雜的管材，要求被檢查的方管表面有一定光潔度，并需有耦合劑充填滿探頭和被檢查表面之間的空隙。昆明經(jīng)開區(qū)Q235熱鍍鋅方管廠</p><p
