鍍鋅鋼管行業怎樣才會有好的發展？
為提高鋼(gang)(gang)管的(de)耐腐蝕性(xing)能(neng)，對一般(ban)鋼(gang)(gang)管進行(xing)鍍(du)(du)(du)鋅(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)焊(han)(han)(han)管分熱鍍(du)(du)(du)鋅(xin)(xin)和冷鍍(du)(du)(du)鋅(xin)(xin)兩(liang)種。鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)管分熱鍍(du)(du)(du)鋅(xin)(xin)和電(dian)鍍(du)(du)(du)鋅(xin)(xin)兩(liang)種，熱鍍(du)(du)(du)鋅(xin)(xin)鍍(du)(du)(du)鋅(xin)(xin)層厚，電(dian)鍍(du)(du)(du)鋅(xin)(xin)成本低，表(biao)面不是(shi)很光滑。吹(chui)(chui)氧焊(han)(han)(han)管：用(yong)(yong)作(zuo)煉鋼(gang)(gang)吹(chui)(chui)氧用(yong)(yong)管，一般(ban)用(yong)(yong)小口徑的(de)焊(han)(han)(han)接鋼(gang)(gang)管，規(gui)格由3/8-2寸(cun)八種。用(yong)(yong)08、10、15、20或(huo)者195-Q235的(de)鋼(gang)(gang)帶制(zhi)作(zuo)成的(de)，為了防腐蝕，有
