冠翔熱鍍鋅、鋼塑管現(xiàn)貨供應(yīng)，全國批發(fā)配送，保質(zhì)保量，歡迎咨詢訂購。 <p> 熱鍍鋅管，為提高鋼管的耐腐蝕性能，對一般鋼管進(jìn)行鍍鋅。鍍鋅鋼管分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，電鍍鋅成本低，表面不是很光滑。 <p> 鍍鋅鋼管存儲注意事項(xiàng)<br /> 鋼管存儲應(yīng)該注意幾點(diǎn)。第1是存儲的位置。它不能放在露天，東營螺旋管在哪里，因?yàn)樵诼短?，不僅會發(fā)生諸如偷取等各種產(chǎn)品的安全，還會發(fā)生腐蝕問題。露天場地很容易受到各種極端天氣條件的影響。大量的雨水或雨雪會較大程度地侵蝕表面上的鍍鋅層，這可能會導(dǎo)致產(chǎn)品生銹。第2是存儲的細(xì)節(jié)。它不直接暴露在太陽光線下。需要冷卻和干燥，不得與腐蝕性物品一起存放。<br
