鍍鋅方管的除銹方法

1、首先利用溶劑清(qing)洗鋼材表面(mian)，把表面(mian)的(de)有機(ji)物去除，

2、然后使(shi)用工(gong)具除(chu)(chu)銹（鋼絲刷）,去除(chu)(chu)松動或傾(qing)斜(xie)的規模，鐵銹，焊渣等,

3、使(shi)用酸洗的方式。

鍍鋅分為熱鍍和冷鍍，熱鍍不(bu)易生銹，冷鍍較易生銹。

鍍(du)鋅(xin)鋼(gang)管(guan)(guan)(guan)(guan)(guan)表面有熱浸鍍(du)或電(dian)鍍(du)鋅(xin)層的(de)焊接鋼(gang)管(guan)(guan)(guan)(guan)(guan)。鍍(du)鋅(xin)可增加鋼(gang)管(guan)(guan)(guan)(guan)(guan)的(de)抗腐(fu)蝕能力，延長使(shi)用(yong)(yong)壽命。鍍(du)鋅(xin)管(guan)(guan)(guan)(guan)(guan)的(de)用(yong)(yong)途(tu)很廣，除作輸水(shui)、煤(mei)氣(qi)、油(you)(you)等一般低壓(ya)力流體(ti)的(de)管(guan)(guan)(guan)(guan)(guan)線管(guan)(guan)(guan)(guan)(guan)外，還(huan)用(yong)(yong)作石油(you)(you)工(gong)業(ye)特別(bie)是海洋(yang)油(you)(you)田的(de)油(you)(you)井管(guan)(guan)(guan)(guan)(guan)、輸油(you)(you)管(guan)(guan)(guan)(guan)(guan)，化工(gong)焦化設備(bei)的(de)油(you)(you)加熱器、冷凝冷卻器、煤(mei)餾洗(xi)油(you)(you)交換器用(yong)(yong)管(guan)(guan)(guan)(guan)(guan)，以及棧橋(qiao)管(guan)(guan)(guan)(guan)(guan)樁(zhuang)、礦山坑道的(de)支(zhi)撐架(jia)用(yong)(yong)管(guan)(guan)(guan)(guan)(guan)等。
