熱鍍鋅圓管具有鍍層均勻，附著力強(qiáng)，使用壽命長等優(yōu)點。熱鍍鋅圓管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反應(yīng)，形成耐腐蝕的結(jié)構(gòu)緊密的鋅一鐵合金層。合金層與純鋅層、鋼管基體融為一體，故其耐腐蝕能力強(qiáng)。 </p> <p> 鍍鋅圓管分為冷鍍鋅圓管、熱鍍鋅圓管。冷鍍鋅圓管已被禁用，熱鍍鋅圓管還被提倡暫時能使用。鍍鋅圓管表面有熱浸鍍或電鍍鋅層的焊接鋼管。鍍鋅可增加鋼管的抗腐蝕能力，延長使用壽命。鍍鋅圓管的用途很廣，除作輸水、煤氣、油等一般低壓力流體的管線管外，還用作石油工業(yè)特別是海洋油田的油井管、輸油管，化工焦化設(shè)備的油加熱器、冷凝冷卻器、煤餾洗油交換器用管，以及棧橋管樁、礦山坑道的支撐架用管等。 </p>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)，它取決于鋼的化學(xué)成分和熱處理制度。在鋼管標(biāo)準(zhǔn)中，根據(jù)不同的使用要求，規(guī)定了拉伸性能（抗拉強(qiáng)度、屈服強(qiáng)度或屈服點、伸長率）以及硬度、韌性指標(biāo)，還有用戶要求的高、低溫性能等。 <p> 屈服點（σs） </p> <p> 具有屈服現(xiàn)象的金屬材料，試樣在拉伸過程中力不增加（保持恒定）仍能繼續(xù)伸長時的應(yīng)力，稱屈服點。若力發(fā)生下降時，則應(yīng)區(qū)分上、下屈服點。屈服點的單位為N/mm2（MPa）。 </p> <p> 上屈服點（σsu）：試樣發(fā)生屈服而力第壹次下降前的比較大應(yīng)力；下屈服點（σsl）：當(dāng)不計初始瞬時效應(yīng)時，屈服階段中的小應(yīng)力。 </p> <p> 屈服點的計算公式為： </p> <p> 式中：Fs--試樣拉伸過程中屈服力（恒定），N（牛頓）So--試樣原始橫截面積，mm2。鍍鋅圓管采用硫酸鹽電鍍鋅鐵合金工藝，即生產(chǎn)線槽和槽全部穿孔直通，無任何溶液流出或溢出。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
