熱鍍鋅管，為提高鋼管的耐腐蝕性能，對(duì)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。

EN1123-1:1999 適用CE認(rèn)證熱鍍鋅管范圍

This standard specifies re, tests and control forlongitudinally welded, hot-dip galvanized steel pipes and fittingswith spigot and socket for use in waste water systems usuallyoperating under gravity or at a low head of pressure. For thepurposes of this standard, components are pipes, fittings, jointsand seals. This standard is for components used for the dischargeof: domestic waste water; surface water; and groundwater. Thisstandard is also for components discharging other waste water (e.g.industrial waste water) as long as it does not damage thecomponents or endanger the health and safety of personnel.

本標(biāo)準(zhǔn)規(guī)定了通常在重力或低壓頭條件下運(yùn)行的廢水系統(tǒng)中使用的帶插口和套筒的縱向焊接熱浸鍍鋅鋼管和管件的要求、試驗(yàn)和質(zhì)量控制。就本標(biāo)準(zhǔn)而言，部件是管道、管件、接頭和密封件。本標(biāo)準(zhǔn)適用于以下排放部件：生活廢水；地表水；以及地下水。本標(biāo)準(zhǔn)也適用于排放其他廢水（如工業(yè)廢水）的部件，只要不會(huì)損壞部件或危及人員的健康和安全。
