• 廠家直(zhi)銷Q235B鍍(du)鋅鋼管(guan) 鍍(du)鋅無縫鋼管(guan) 鍍(du)鋅方管(guan) 熱鍍(du)鋅消防鋼管(guan)

  鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)(guan)分(fen)為冷(leng)鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)(guan)、熱鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)(guan)，冷(leng)鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)(guan)已被禁用(yong)(yong)(yong)，后者還被****提倡暫時能使用(yong)(yong)(yong)。六七十年代，國際(ji)上發(fa)達(da)****開始開發(fa)新(xin)型管(guan)(guan)(guan)(guan)材，并陸(lu)續禁用(yong)(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)。中(zhong)國建(jian)設(she)部等四部委也發(fa)文明(ming)確(que)從2000年起禁用(yong)(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)作(zuo)為供水管(guan)(guan)(guan)(guan)，新(xin)建(jian)小區的(de)冷(leng)水管(guan)(guan)(guan)(guan)已經很少使用(yong)(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)了(le)，有些小區的(de)熱水管(guan)(guan)(guan)(guan)使用(yong)(yong)(yong)的(de)是鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)(guan)。熱鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)(guan)在消防、電(dian)力和高速(su)公路上有廣(guang)泛(fan)的(de)應用(yong)(yong)(yong)。

  熱鍍鋅鋼(gang)管廣泛應用于建(jian)筑、機(ji)械、煤礦(kuang)、化工、電(dian)力、鐵道車輛、汽車工業、公路、橋梁、集裝箱、體育設施(shi)、農(nong)業機(ji)械、石油機(ji)械、探礦(kuang)機(ji)械等制造(zao)工業。

  鍍(du)鋅鋼管表面有熱(re)浸鍍(du)或(huo)電(dian)鍍(du)鋅層的(de)(de)(de)焊接鋼管。鍍(du)鋅可增(zeng)加鋼管的(de)(de)(de)抗腐(fu)蝕能力，延(yan)長使用(yong)壽命(ming)。鍍(du)鋅管的(de)(de)(de)用(yong)途(tu)很(hen)廣，除作(zuo)輸水、煤氣(qi)、油(you)(you)(you)等一(yi)般低壓力流體的(de)(de)(de)管線管外，還(huan)用(yong)作(zuo)石(shi)油(you)(you)(you)工(gong)業特別是海(hai)洋油(you)(you)(you)田(tian)的(de)(de)(de)油(you)(you)(you)井管、輸油(you)(you)(you)管，化(hua)工(gong)焦化(hua)設備的(de)(de)(de)油(you)(you)(you)加熱(re)器(qi)、冷凝(ning)冷卻器(qi)、煤餾(liu)洗(xi)油(you)(you)(you)交換器(qi)用(yong)管，以及棧橋管樁(zhuang)、礦山坑道的(de)(de)(de)支撐(cheng)架用(yong)管等。
