鍍鋅管由于是堆放在室外的，而且在使用的時(shí)候，大部分都是埋在地底的，所以很容易腐蝕和生銹，為了保證管道的暢通，所以要求鍍鋅管必須較強(qiáng)的耐腐性。一旦管道被腐蝕，會造成油、氣的滲漏，不僅使運(yùn)輸中斷，而且會污染環(huán)境，甚至可能引起火災(zāi)，造成危害。鍍鋅管生產(chǎn)廠家給大家講講造成鍍鋅管腐蝕的因素： </p> <p> 1、防腐失效。管道在架設(shè)的時(shí)候要做好防腐工作或者直接使用防腐螺旋鋼管，管道遭到腐蝕的原因是因?yàn)楣艿赖姆栏瘜釉獾搅似茐摹７栏瘜雍凸艿辣砻嬉坏┟撾x，就會自然造成防腐失效。這也梯式我們在選購鍍鋅管時(shí)要選用防腐鍍鋅管。 </p> <p> 2、外界條件的影響。主要是先看管道周圍的介質(zhì)特性、溫度，以及管道周圍所處的介質(zhì)是不是具有腐蝕性。因?yàn)榻橘|(zhì)腐蝕性的高低與土壤所含的各項(xiàng)微生物有著密切的關(guān)系。并且如果是長輸管道的話，土壤環(huán)境性質(zhì)更加復(fù)雜。除此之外，管道所處環(huán)境的溫度也會影響鍍鋅管的腐蝕，如果溫度較高，腐蝕的速度也會加快，而溫度低則腐蝕速度減慢。 </p> <p> <br /> </p><p style="text-indent:25px"><span style="font-size:14px;"> 熱鍍鋅管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進(jìn)行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長等優(yōu)點(diǎn)。鋼管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反應(yīng)，形成耐腐蝕的結(jié)構(gòu)緊密的鋅一鐵合金層。合金層與純鋅層、鋼管基體融為一體。故其耐腐蝕能力強(qiáng)。鍍鋅鋼管具有如下生產(chǎn)步驟：黑件檢查→掛料→脫脂→漂洗→酸洗→清洗→浸漬助鍍劑→熱空氣烘干→熱浸鍍鋅→冷卻→鈍化和漂洗→卸料→檢驗(yàn)、修整→包裝入庫、運(yùn)輸。</span>鍍鋅管的焊接注意要點(diǎn)是什么？</p><div
