style="text-indent:25px">如今熱鍍鋅無縫管作為常用的消防管類型，在防火安全領(lǐng)域發(fā)揮著不可替代的作用。直到現(xiàn)在，熱鍍鋅依然是鋼材防腐蝕方法中較普遍、較有效的工藝措施。鍍鋅保護(hù)鋼材的原理在于：除了形成一層外覆蓋層，阻隔空氣和水分對圓管的侵蝕外，還利用的鋼比鋅的電負(fù)性，通過優(yōu)先氧化鍍鋅層，**掉鋅來保護(hù)鋼鐵。因此，普通圓管的防腐蝕能力是難以望其項(xiàng)背的，即便是經(jīng)過涂油涂漆等防腐手段處理過的鋼材，防腐蝕能力也無法和熱鍍鋅無縫管相比。熱鍍鋅層的防腐年限，根據(jù)各個行業(yè)發(fā)布的行業(yè)標(biāo)準(zhǔn)來綜合對比，只要鋅層厚度（Zn-Fe合金層+Zn層）不低于標(biāo)準(zhǔn)規(guī)定的厚度值，沿海地區(qū)環(huán)境下，可以達(dá)到50年防腐、內(nèi)陸地區(qū)可以達(dá)到70年防腐期，且在防腐服役期內(nèi)，幾乎為零維護(hù)。因此，關(guān)乎民眾生命財(cái)產(chǎn)安全大計(jì)的消防管，就理當(dāng)選擇安全耐用的熱鍍鋅無縫圓管了。熱鍍鋅無縫管: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。</p><div

style="text-indent:25px">冷熱鍍鋅圓管就是電鍍鋅，鍍鋅量很少，只有10-50g/m2，其本身的耐腐蝕性比熱鍍鋅圓管相差很多。正規(guī)的熱鍍鋅圓管生產(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)然他們的價格也相對便宜一些。建設(shè)部已正式下文，淘汰技術(shù)落后的冷熱鍍鋅圓管，不準(zhǔn)用冷熱鍍鋅圓管作水、煤氣管。冷鍍鋅圓管鍍鋅層是電鍍層，鋅層與圓管基體**分層。鋅層較薄，鋅層簡單附著在圓管基體上，容易脫落。故其耐腐蝕性能差。在新建住宅中，禁止使用冷鍍鋅圓管作為給水管。采用的穿孔和軋管方法不同，就構(gòu)成了生產(chǎn)無縫圓管的不同方法。廣西低合金無縫管采購</p><p
