熱鍍鋅也稱熱浸鍍鋅，是鋼鐵構(gòu)件浸入熔融的鋅液中獲得金屬覆蓋層的一種方法。隨高壓輸電、交通、通訊事業(yè)迅速發(fā)展，對(duì)鋼鐵件防護(hù)要求越來越高，熱鍍鋅需求量也不斷增加。 </p> <p> 熱鍍鋅具有很強(qiáng)的防護(hù)性能 </p> <p> 通常電鍍鋅層厚度5～15μm，而熱鍍鋅層一般在35μm以上，甚至高達(dá)200μm。熱鍍鋅覆蓋能力好，鍍層致密，無有機(jī)物夾雜。眾所周知，鋅的抗大氣腐蝕的機(jī)理有機(jī)械保護(hù)及電化學(xué)保護(hù)，在大氣腐蝕條件下鋅層表面有ZnO、Zn(OH)2及堿式碳酸鋅保護(hù)膜，一定程度上減緩鋅的腐蝕，這層保護(hù)膜(也稱白銹)受到破壞又會(huì)形成新的膜層。當(dāng)鋅層破壞嚴(yán)重，危及到鐵基體時(shí)，鋅對(duì)基體產(chǎn)生電化學(xué)保護(hù)，鋅的標(biāo)準(zhǔn)電位-0.76V，鐵的標(biāo)準(zhǔn)電位-0.44V，鋅與鐵形成微電池時(shí)鋅作為陽極被溶解，鐵作為陰極受到保護(hù)。顯然熱鍍鋅對(duì)基體金屬鐵的抗大氣腐蝕能力優(yōu)于電鍍鋅。

）、鋼筋的公稱直徑、公稱重量（質(zhì)量）、規(guī)定長度及上述指標(biāo)的允差值等各項(xiàng)。我國標(biāo)準(zhǔn)推薦公稱直徑為8、10、12、16、20、40mm的螺旋鋼管系列。供貨長度分定尺和倍尺二種。我國出口螺紋鋼定尺選擇范圍為6～12m，日本產(chǎn)螺紋鋼定尺選擇范圍為3.5～10m。 </p> <p> 外觀質(zhì)量：①表面質(zhì)量。有關(guān)標(biāo)準(zhǔn)中對(duì)螺紋鋼的表面質(zhì)量作了規(guī)定，要求端頭應(yīng)切得平直，表面不得有裂縫、結(jié)疤和折迭，不得存在使用上有害的缺陷等；②外形尺寸偏差允許值。螺紋鋼的彎曲度及鋼筋幾何形狀的要求在有關(guān)標(biāo)準(zhǔn)中作了規(guī)定。如我國標(biāo)準(zhǔn)規(guī)定，直條鋼筋的彎曲度不大于6mm/m，總彎曲度不大于鋼筋總長度的0.6%。生產(chǎn)螺旋鋼管時(shí)需注意哪些？批發(fā)熱鍍管的廠家</p><p style="text-indent:25px">鍍鋅鋼管主要用途和工藝特點(diǎn)有哪些？批發(fā)熱鍍管的廠家</p><p> 焊接鋼管也稱焊管，是用鋼板或鋼帶經(jīng)過卷曲成型后焊接制成的鋼管。焊接鋼管生產(chǎn)工藝簡單，生產(chǎn)效率高，品種規(guī)格多，設(shè)備投資少，但一般強(qiáng)度低于無縫鋼管。20世紀(jì)30年代以來，隨著優(yōu)異帶鋼連軋生產(chǎn)的迅速發(fā)展以及焊接和檢驗(yàn)技術(shù)的進(jìn)步，焊縫質(zhì)量不斷提高，焊接鋼管的品種規(guī)格日益增多，并在越來越多的領(lǐng)域代替了無縫鋼管。焊接鋼管按焊縫的形式分為直縫焊管和螺旋焊管。 </p> <p> 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(qiáng)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30~100 %，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。
