Q235 鍍鋅(xin)鋼管 現貨(huo)供應規(gui)格齊(qi)全

鍍(du)鋅(xin)鋼(gang)管(guan)分(fen)為冷鍍(du)鋅(xin)鋼(gang)管(guan)、熱鍍(du)鋅(xin)鋼(gang)管(guan)，冷鍍(du)鋅(xin)鋼(gang)管(guan)已(yi)被(bei)禁用(yong)(yong)(yong)，后者還被(bei)提倡暫時(shi)能使(shi)(shi)用(yong)(yong)(yong)。六七(qi)十年代，國(guo)際上(shang)發(fa)達開始開發(fa)新型管(guan)材，并(bing)陸續禁用(yong)(yong)(yong)鍍(du)鋅(xin)管(guan)。中(zhong)國(guo)建(jian)設部(bu)等四部(bu)委也發(fa)文明確(que)從2000年起禁用(yong)(yong)(yong)鍍(du)鋅(xin)管(guan)作為供水(shui)管(guan)，新建(jian)小(xiao)(xiao)區的(de)冷水(shui)管(guan)已(yi)經很(hen)少使(shi)(shi)用(yong)(yong)(yong)鍍(du)鋅(xin)管(guan)了，有些小(xiao)(xiao)區的(de)熱水(shui)管(guan)使(shi)(shi)用(yong)(yong)(yong)的(de)是(shi)鍍(du)鋅(xin)管(guan)。熱鍍(du)鋅(xin)鋼(gang)管(guan)在(zai)消防、電力(li)和高速公路上(shang)有廣泛的(de)應用(yong)(yong)(yong)。

熱(re)鍍鋅鋼管廣泛(fan)應用于建(jian)筑、機械(xie)、煤礦(kuang)、化工(gong)(gong)、電力、鐵(tie)道車輛、汽車工(gong)(gong)業、公路、橋梁、集(ji)裝箱、體育設(she)施、農業機械(xie)、石油機械(xie)、探礦(kuang)機械(xie)等制造工(gong)(gong)業。

鍍(du)(du)(du)鋅鋼管(guan)(guan)表面有熱(re)浸(jin)鍍(du)(du)(du)或電(dian)鍍(du)(du)(du)鋅層的(de)(de)焊接鋼管(guan)(guan)。鍍(du)(du)(du)鋅可增加鋼管(guan)(guan)的(de)(de)抗(kang)腐(fu)蝕(shi)能力，延長使用(yong)(yong)壽(shou)命。鍍(du)(du)(du)鋅管(guan)(guan)的(de)(de)用(yong)(yong)途很廣(guang)，除作(zuo)輸(shu)水、煤氣(qi)、油(you)等一般(ban)低壓力流體的(de)(de)管(guan)(guan)線管(guan)(guan)外，還用(yong)(yong)作(zuo)石油(you)工業特別是海洋(yang)油(you)田的(de)(de)油(you)井(jing)管(guan)(guan)、輸(shu)油(you)管(guan)(guan)，化(hua)工焦化(hua)設(she)備的(de)(de)油(you)加熱(re)器(qi)、冷(leng)凝(ning)冷(leng)卻(que)器(qi)、煤餾洗(xi)油(you)交換器(qi)用(yong)(yong)管(guan)(guan)，以及棧橋管(guan)(guan)樁、礦(kuang)山坑道的(de)(de)支撐架用(yong)(yong)管(guan)(guan)等。
