鍍鋅鋼管用鋼的牌號(hào)和化學(xué)成分應(yīng)符合GB/T3092所規(guī)定的黑管用鋼的牌號(hào)和化學(xué)成分。 </p> <p> 2、制造方法 </p> <p> 黑管的制造方法（爐焊或電焊）由制造廠選擇。鍍鋅采用熱浸鍍鋅法。 </p> <p> 3、螺紋及管接頭 </p> <p> （a）帶螺紋交貨的鍍鋅鋼管，螺紋應(yīng)在鍍鋅后車制。螺紋應(yīng)符合YB 822的規(guī)定。 </p> <p> （b）鋼制管接頭應(yīng)符合YB 238的規(guī)定；可鍛鑄鐵管接頭應(yīng)符合YB 230的規(guī)定。 </p> <p> 4、力學(xué)性能鋼管鍍鋅前的力學(xué)性能應(yīng)符合GB 3092的規(guī)定。 </p> <p> 5、鍍鋅層的均勻性鍍鋅鋼管應(yīng)作鍍鋅層均勻性的試驗(yàn)。鋼管試樣在硫酸銅溶液中連續(xù)浸漬5次不得變紅（鍍銅色）。 </p> <p> 6、冷彎曲試驗(yàn)公稱口徑不大于50mm的鍍鋅鋼管應(yīng)作冷彎曲試驗(yàn)。彎曲角度為90°，彎曲半徑為外徑的8倍。試驗(yàn)時(shí)不帶填充物，試樣焊縫處應(yīng)置于彎曲方向的外側(cè)或上部。試驗(yàn)后，試樣上不應(yīng)有裂縫及鋅層剝落同象。 </p> <p> 7、水壓試驗(yàn)水壓試驗(yàn)應(yīng)在黑管進(jìn)行，也可用渦流探傷代替水壓試驗(yàn)。試驗(yàn)壓力或渦流探傷對(duì)比試樣尺寸應(yīng)符合GB 3092的規(guī)定。鋼材力學(xué)性能是保證鋼材**終使用性能（機(jī)械性能）的重要指標(biāo)。 </p> <p> <br /> </p><p> 美鋼聯(lián)法 </p> <p> 它是森吉米爾法的一個(gè)變種，它**是利用一個(gè)堿性電解脫脂槽取代了氧化爐的脫脂作用，其余工序與森吉米爾法基本相同。在原板進(jìn)入作業(yè)線后，首先進(jìn)行電解脫脂，而后水洗、烘干，再通過(guò)有保護(hù)氣體的還原爐進(jìn)行再結(jié)晶退火，***在密封情況下進(jìn)入鋅鍋熱鍍鋅。這種方法因帶鋼不經(jīng)過(guò)氧化爐加熱，所以表面的氧化膜較薄，可適當(dāng)降低還原爐中保護(hù)氣體的氫含量。這樣，對(duì)爐安全和降低生產(chǎn)成本有利。但是，由于帶鋼得不到預(yù)加熱就進(jìn)入還原爐中，這樣無(wú)疑提高了還原爐的熱負(fù)荷，影響爐子的壽命。因此這種方法并未得廣泛應(yīng)用。

熱鍍鋅鋼管選用的是熱鍍鋅加工工藝，無(wú)縫鋼管的內(nèi)、表面常有鋅層。 </p> <p> 差別： </p> <p> 1、加工工藝有差別，一個(gè)是有機(jī)化學(xué)解決，一個(gè)是物理學(xué)解決;熱浸鍍鋅涂層牢固，不容易掉下來(lái) </p> <p> 2、熱浸鍍鋅涂層厚，因此防腐蝕工作能力強(qiáng)。而熱鍍鋅(電鍍工藝)涂層勻稱，工藝性能不錯(cuò)，涂層薄厚一般在幾微米至十幾μm中間。 </p> <p> 3、熱浸鍍鋅是有機(jī)化學(xué)解決，歸屬于電化學(xué)腐蝕。熱鍍鋅是物理學(xué)解決，**在表層刷一層鋅，里邊壓根就沒(méi)有熱鍍鋅，因此鋅層易掉下來(lái)。建筑工程施工中有選用熱浸鍍鋅。 </p> <p>
