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)乎民眾生命財產(chǎn)安全大計的消防管，就理當(dāng)選擇安全耐用的熱鍍鋅無縫圓管了。</p><p style="text-indent:25px">無縫管多多少少都會有管壁厚不均勻的現(xiàn)象，這是生產(chǎn)工藝方式造成的，與技術(shù)高低無關(guān)。管壁厚不均勻會容易爆裂，特別是用于壓力管道、壓力容器方面。不銹鋼焊管就能解決這個問題，采用鋼材或鋼帶經(jīng)過機(jī)組和模具卷曲成型后焊接制而成；不銹鋼焊管擁有生產(chǎn)工藝簡單、生產(chǎn)效率高、管壁厚度均勻的優(yōu)點。隨著焊接和檢驗技術(shù)的進(jìn)步，不銹圓管焊縫質(zhì)量不斷提高，焊接不銹圓管的品種規(guī)格日益增多，并在越來越多的領(lǐng)域尤其是在換熱設(shè)備用管、裝飾管、中低壓流體管等方面代替了無縫圓管。液壓和氣動缸筒用精密內(nèi)徑無縫管是制造液壓和氣動缸筒用的具有精密內(nèi)徑尺寸的冷拔或冷軋精密無縫管。</p><div

style="text-indent:25px">專門用途的無縫管有鍋爐用無縫管、地質(zhì)用無縫圓管及石油用無縫管等多種。焊接圓管也稱焊管，是用鋼板或鋼帶經(jīng)過卷曲成型后焊接制成的圓管圓管。焊接圓管生產(chǎn)工藝簡單，生產(chǎn)效率高，品種規(guī)格多，設(shè)備資少，但一般強度低于無縫圓管。20世紀(jì)30年代以來，隨著優(yōu)良帶鋼連軋生產(chǎn)的迅速發(fā)展以及焊接和檢驗技術(shù)的進(jìn)步，焊縫質(zhì)量不斷提高，焊接圓管的品種規(guī)格日益增多，并在越來越多的領(lǐng)域代替了無縫圓管。焊接圓管按焊縫的形式分為直縫焊管和螺旋焊管。直縫焊管生產(chǎn)工藝簡單，生產(chǎn)效率高，成本低，發(fā)展較快。螺旋焊管的強度一般比直縫焊管高，能用較窄的坯料生產(chǎn)管徑較大的焊管，還可以用同樣寬度的坯料生產(chǎn)管徑不同的焊管。但是與相同長度的直縫管相比，焊縫長度增加30~完全，而且生產(chǎn)速度較低。因此，較小口徑的焊管大都采用直縫焊，大口徑焊管則大多采用螺旋焊。廣東包鋼無縫管價格</p><p
