鍍鋅鋼管行業怎樣才會有好的發展？
為(wei)提高(gao)鋼管(guan)(guan)(guan)(guan)的耐腐蝕性能，對一(yi)般鋼管(guan)(guan)(guan)(guan)進行鍍(du)(du)鋅(xin)(xin)。鍍(du)(du)鋅(xin)(xin)焊管(guan)(guan)(guan)(guan)分熱鍍(du)(du)鋅(xin)(xin)和(he)冷鍍(du)(du)鋅(xin)(xin)兩種。鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)(guan)分熱鍍(du)(du)鋅(xin)(xin)和(he)電鍍(du)(du)鋅(xin)(xin)兩種，熱鍍(du)(du)鋅(xin)(xin)鍍(du)(du)鋅(xin)(xin)層厚，電鍍(du)(du)鋅(xin)(xin)成本低，表面不是很光滑(hua)。吹氧焊管(guan)(guan)(guan)(guan)：用(yong)作(zuo)煉鋼吹氧用(yong)管(guan)(guan)(guan)(guan)，一(yi)般用(yong)小(xiao)口(kou)徑的焊接鋼管(guan)(guan)(guan)(guan)，規格由3/8-2寸(cun)八種。用(yong)08、10、15、20或者(zhe)195-Q235的鋼帶制作(zuo)成的，為(wei)了防(fang)腐蝕，有
