2、鍍鋅層的均勻性鍍鋅鋼管應(yīng)作鍍鋅層均勻性的試驗。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> 3、冷彎曲試驗公稱口徑不大于50mm的鍍鋅鋼管應(yīng)作冷彎曲試驗。彎曲角度為90°，彎曲半徑為外徑的8倍。試驗時不帶填充物，試樣焊縫處應(yīng)置于彎曲方向的外側(cè)或上部。試驗后，試樣上不應(yīng)有裂縫及鋅層剝落同象。 </p> <p> 4、水壓試驗水壓試驗應(yīng)在黑管進行，也可用渦流探傷代替水壓試驗。試驗壓力或渦流探傷對比試樣尺寸應(yīng)符合GB3092的規(guī)定。 </p> <p> 鋼材力學(xué)性能是保證鋼材**終使用性能(機械性能)的重要指標，它取決于鋼的化學(xué)成分和熱處理制度。在鋼管標準中，根據(jù)不同的使用要求，規(guī)定了拉伸性能(抗拉強度、屈服強度或屈服點、伸長率)以及硬度、韌性指標，還有用戶要求的高、低溫性能等。 </p><p> 鍍鋅管的主要工藝特點是什么 </p> <p> 電鍍設(shè)備的特殊性 </p> <p> 鍍鋅管鍍銅屬于連續(xù)電鍍，但電鍍設(shè)備不同。線材鍍液設(shè)計具有細長帶狀的特點，本體長、寬、淺。電鍍時，鐵絲穿過孔，在液面上呈之字形展開，以保持相互間隔。鍍鋅管不同于鐵絲，有其獨特的特點，坡口設(shè)備更加復(fù)雜。罐體由上部和下部組成。上部為電鍍槽，下部為溶液循環(huán)儲罐，形成窄上寬下的梯形罐體。電鍍槽中有一個鍍鋅管道電鍍操作的通道。罐體底部有兩個通孔與下部儲罐相連，下泵形成電鍍液循環(huán)再利用系統(tǒng)。因此，鍍鋅管像鐵絲電鍍一樣是動態(tài)的，鍍鋅管的電鍍液也是動態(tài)的。線材鍍液設(shè)計具有細長帶狀的特點，本體長、寬、淺。</p><div
