鍍(du)鋅(xin)管(guan)折彎 大棚用鍍(du)鋅(xin)管(guan) Q345B鍍(du)鋅(xin)鋼(gang)管(guan)

鍍(du)(du)(du)鋅鋼(gang)管(guan)(guan)(guan)(guan)分(fen)為(wei)(wei)冷鍍(du)(du)(du)鋅鋼(gang)管(guan)(guan)(guan)(guan)、熱(re)鍍(du)(du)(du)鋅鋼(gang)管(guan)(guan)(guan)(guan)，冷鍍(du)(du)(du)鋅鋼(gang)管(guan)(guan)(guan)(guan)已被禁用(yong)(yong)，后者還被提倡暫時能使(shi)用(yong)(yong)。六七十年(nian)代，國(guo)際上發達開始開發新型(xing)管(guan)(guan)(guan)(guan)材，并陸續(xu)禁用(yong)(yong)鍍(du)(du)(du)鋅管(guan)(guan)(guan)(guan)。中國(guo)建設部等(deng)四部委(wei)也發文明確(que)從2000年(nian)起禁用(yong)(yong)鍍(du)(du)(du)鋅管(guan)(guan)(guan)(guan)作為(wei)(wei)供水(shui)(shui)管(guan)(guan)(guan)(guan)，新建小區(qu)的冷水(shui)(shui)管(guan)(guan)(guan)(guan)已經很少使(shi)用(yong)(yong)鍍(du)(du)(du)鋅管(guan)(guan)(guan)(guan)了，有(you)些(xie)小區(qu)的熱(re)水(shui)(shui)管(guan)(guan)(guan)(guan)使(shi)用(yong)(yong)的是鍍(du)(du)(du)鋅管(guan)(guan)(guan)(guan)。熱(re)鍍(du)(du)(du)鋅鋼(gang)管(guan)(guan)(guan)(guan)在消防、電力和高速公(gong)路(lu)上有(you)廣泛的應用(yong)(yong)。

熱鍍鋅鋼管(guan)廣泛應用(yong)于建筑、機(ji)械、煤礦、化(hua)工(gong)、電力、鐵道車(che)輛(liang)、汽車(che)工(gong)業、公路、橋梁、集(ji)裝箱、體(ti)育設施、農(nong)業機(ji)械、石油機(ji)械、探礦機(ji)械等制(zhi)造(zao)工(gong)業。

鍍(du)鋅(xin)(xin)(xin)鋼管(guan)表面有熱浸鍍(du)或電鍍(du)鋅(xin)(xin)(xin)層(ceng)的(de)(de)(de)焊接鋼管(guan)。鍍(du)鋅(xin)(xin)(xin)可增加鋼管(guan)的(de)(de)(de)抗(kang)腐蝕能力(li)，延長使用(yong)壽命。鍍(du)鋅(xin)(xin)(xin)管(guan)的(de)(de)(de)用(yong)途很廣，除(chu)作輸水、煤氣、油(you)等(deng)一般低壓力(li)流體的(de)(de)(de)管(guan)線管(guan)外，還(huan)用(yong)作石油(you)工(gong)業特別(bie)是海(hai)洋油(you)田的(de)(de)(de)油(you)井管(guan)、輸油(you)管(guan)，化工(gong)焦(jiao)化設備的(de)(de)(de)油(you)加熱器、冷(leng)凝冷(leng)卻器、煤餾洗油(you)交換器用(yong)管(guan)，以及棧橋管(guan)樁(zhuang)、礦山坑道的(de)(de)(de)支撐架用(yong)管(guan)等(deng)。
