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。 </p><p> 因為鍍鋅鋼管的內(nèi)表層無空氣氧化層，髙壓，沒有滲漏，高精度，光澤度高，冷拔不形變，伸開，展開，無裂紋，因而適用于生產(chǎn)制造。具備氣動式或液壓機部件的商品(比如氣罐或氣罐)能夠是無縫拼接的。 </p> <p> 電焊焊接并接受的鍍鋅鋼管也具備高精密，而且水管表層的表層光滑度也很高。無縫鋼管開展調(diào)質(zhì)處理后，表層無空氣氧化膜，無縫鋼管伸開，展開，無裂紋，冷拔不形變。能夠承擔髙壓，能保證不一樣雜亂無章形變和機械設(shè)備生產(chǎn)加工。 </p> <p>
