style="text-indent:25px">熱鍍鋅管的技術(shù)要求：①抗拉強度（σb）試樣在拉伸過程中，在拉斷時所承受的比較大力（Fb），出以試樣原橫截面積（So）所得的應(yīng)力（σ），稱為抗拉強度（σb），單位為N/mm2（MPa）。它表示金屬材料在拉力作用下抵抗破壞的比較大能力。計算公式為：式中：Fb--試樣拉斷時所承受的比較大力，N（牛頓）； So--試樣原始橫截面積，mm2。②屈服點（σs）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）。鍍鋅管鍍銅屬于連續(xù)電鍍，但電鍍設(shè)備不同。</p><div

粉塵：鍍鋅鋼管公司介紹，制作經(jīng)常是在有粉塵的場地進行，空氣中常帶有許多粉塵，它們不斷地落在設(shè)備表面。它們可以用水或堿性溶液去除掉。不過，有附著力的塵垢需要高壓水或蒸氣進行清理。 </p> <p> 劃痕：為了防止工藝潤滑劑或生成物和/或污物積留，必須對劃痕和其它粗糙表面進行機械清理(如干噴砂,磨料用玻璃珠)。 </p> <p> 銹斑：鍍鋅鋼管廠家分析，制作前或制作過程中有時會看到不銹鋼產(chǎn)品或設(shè)備上生銹，這說明表面受到嚴(yán)重污染。設(shè)備投入使用前必須把銹清理掉，徹底清理過的表面應(yīng)通過鐵試驗和/或水試驗進行檢驗。 </p> <p> 焊接引弧斑痕：焊工在金屬表面引弧時，會造成表面粗糙缺點。保護膜受損，留下潛在的腐蝕源。焊工應(yīng)在已經(jīng)焊好的焊道上或在焊縫接頭的側(cè)邊引弧。然后將引弧痕跡熔入焊縫中。熱鍍鋅鋼管和無縫鋼管的有什么不同？昆明Q355B熱鍍鋅管廠</p><p
