鍍鋅鋼管的鍍鋅方法

日期:2020-02-25

鍍鋅鋼管鍍鋅的方式是熱浸鍍鋅和電鍍鋅有兩大類。熱浸鍍鋅包括濕法,干法,鉛鋅法和氧化還原法。 

鍍鋅鋼管的鍍鋅方法

不同的熱浸鍍鋅方法之間的主要區別在于,在對鋼管進行酸浸清洗后,如何激活管體表面以提高鍍鋅質量。干法生產和氧化還原方法主要用于生產中。 

鍍鋅鋅層表面非常光滑致密,結構均勻。具有良好的機械性能和耐腐蝕性;與熱鍍鋅相比,鋅的消耗量降低了60%至75%。電鍍鋅在技術上很復雜,但是該方法必須用于單面涂層,內外表面厚度不同的雙面涂層以及薄壁鍍鋅。 

靜水壓試驗應在黑管中進行。也可以使用渦流探傷代替靜水壓試驗。試驗壓力或渦流檢驗比較試樣的尺寸應符合GB3092的要求。
