熱鍍鋅方管在鍍鋅以后，表面覆蓋了一層鋅的涂層，使方管和大氣隔了開來，避免了大氣對(duì)方管的直接接觸和銹蝕，得到了保護(hù)。而鋅在方管表面的涂層，由于鋅的化學(xué)活性比較強(qiáng)，常溫下在空氣中就會(huì)形成薄而致密的一層碳酸鋅，保護(hù)鋅自身不會(huì)繼續(xù)被氧化。因此鍍鋅方管，不管是表層的鋅還是方管本身都得到了保護(hù)，不會(huì)生銹，不需要刷防銹漆。只有當(dāng)鍍鋅層被破壞，（比如方管焊接，接頭處涂層燒毀），方管裸露于空氣當(dāng)中，失去了鍍鋅層保護(hù)，此時(shí)才需補(bǔ)刷防銹漆。昆明五華區(qū)熱鍍鋅方管規(guī)格型號(hào)表高鋅層熱鍍鋅方管在工業(yè)，農(nóng)業(yè)、建筑、橋梁、運(yùn)輸?shù)确矫?，近幾年已大量地被采用?/p><div

一般情況下，殘次的熱鍍鋅方管是呈現(xiàn)一個(gè)折疊狀態(tài)的，而這種折疊狀態(tài)的熱鍍鋅方管的外表，是構(gòu)成了這種折線的主要原因，這種缺點(diǎn)，往往就是貫穿著整個(gè)產(chǎn)物的縱向，而發(fā)生折疊的緣由，就可能是由于一些達(dá)不到要求的生產(chǎn)廠家，過于追求高的效率，而這樣在壓下量偏大的時(shí)候，就會(huì)產(chǎn)生這種折疊，而如果使用這種折疊的熱鍍鋅方管，進(jìn)行折彎之后可能會(huì)出現(xiàn)開裂，這樣的鋼材強(qiáng)度并不大。 </p> <p> 而一些殘次的熱鍍鋅方管，在表面上面還會(huì)出現(xiàn)麻面的現(xiàn)象，而這些麻面，是可能因?yàn)樯a(chǎn)廠家，所使用的生產(chǎn)設(shè)備的表面，不規(guī)則和高低不平而引起的，這樣因?yàn)闅埓蔚臒徨冧\方管，往往會(huì)讓生產(chǎn)設(shè)備超支，所以外表就會(huì)出現(xiàn)麻面的現(xiàn)象。而往往質(zhì)量不是很好的熱鍍鋅方管，還是會(huì)容易產(chǎn)生結(jié)疤，因?yàn)橐话阗|(zhì)量不高的熱鍍鋅方管，所生產(chǎn)的原材料都大多不是很均勻，其中所含的雜志比較高。并且低質(zhì)量的的生產(chǎn)設(shè)備，也大多非常的簡(jiǎn)陋，很容易就會(huì)造成粘鋼等問題，這樣就會(huì)在生產(chǎn)出來的熱鍍鋅方管，上面出現(xiàn)疤。 </p><p> 熱鍍鋅方管鑒別好壞的方法： </p> <p> 熱鍍鋅方管易出現(xiàn)折疊。折疊是熱鍍鋅方管表面形成的各種折線，這種缺陷往往貫穿整個(gè)產(chǎn)品的縱向。產(chǎn)生折疊的原因是由于廠家追求高效率，壓下量偏大，產(chǎn)生耳子，下一道軋制時(shí)就產(chǎn)生折疊，折疊的產(chǎn)品折彎后就會(huì)開裂，鋼材的強(qiáng)度大下降。 </p> <p> 熱鍍鋅方管外表經(jīng)常有麻面現(xiàn)象。麻面是由于軋槽磨損嚴(yán)重引起鋼材表面不規(guī)則的凹凸不平的缺陷。由于熱鍍鋅方管廠家要追求利潤(rùn)，經(jīng)常出現(xiàn)軋槽軋制超標(biāo)。 </p> <p> 熱鍍鋅方管表面易產(chǎn)生結(jié)疤。原因有兩點(diǎn)：(1)．熱鍍鋅方管材質(zhì)不均勻，雜質(zhì)多。(2)。廠家導(dǎo)衛(wèi)設(shè)備簡(jiǎn)陋，容易粘鋼，這些雜質(zhì) </p> <p> 材表面易產(chǎn)生裂紋，原因是它的坯料是土坯，土坯氣孔多，土坯在冷卻的過程中由于受到熱應(yīng)力的作用，產(chǎn)生裂痕，經(jīng)過軋制后就有裂紋。 </p> <p> 熱鍍鋅方管容易刮傷，原因是熱鍍鋅方管廠家設(shè)備簡(jiǎn)陋，易產(chǎn)生毛刺，刮傷鋼材表面。深度刮傷降低鋼材的強(qiáng)度。 </p> <p> 熱鍍鋅方管無金屬光澤，呈淡紅色或原因有兩點(diǎn)二、它的坯料是土坯。材軋制的溫度不標(biāo)準(zhǔn)，他們的鋼溫是通過目測(cè)的，這樣無法按規(guī)定的奧氏體區(qū)域進(jìn)行軋制，鋼材的性能自然就無法達(dá)標(biāo)。 </p> <p> 熱鍍鋅方管的橫筋細(xì)而低，經(jīng)常出現(xiàn)充不滿的現(xiàn)象，原因是廠家為大的負(fù)公差，成品前幾道的壓 </p> <p> <br /> 鍍鋅方管管體與插接法蘭間的連接應(yīng)采用無鉚釘連接工藝，運(yùn)用進(jìn)口設(shè)備進(jìn)行無鉚釘連接工藝。</p><div style="width:100%;text-align:
