廠家直(zhi)銷防腐保溫(wen)鋼(gang)(gang)管 螺旋 直(zhi)縫(feng)焊(han)接(jie)鋼(gang)(gang)管 現(xian)貨庫存(cun) 量(liang)大優惠

保溫(wen)鋼管(guan)（Heat preservation pipe）是經過保溫(wen)工(gong)(gong)(gong)藝加工(gong)(gong)(gong)處理后(hou)，在(zai)不同工(gong)(gong)(gong)作環(huan)境和外介質的作用下保證工(gong)(gong)(gong)作鋼管(guan)內溫(wen)度與表面溫(wen)度符合(he)或達(da)到使(shi)用要求(qiu)的鋼制管(guan)道。

保(bao)溫(wen)管道廣泛用于(yu)液體(ti)、氣(qi)體(ti)的輸(shu)送管網， 化工管道保(bao)溫(wen)工程(cheng)石油、化工、集中供熱熱網、中央空調(diao)通(tong)風管道、市政工程(cheng)等。

保(bao)(bao)(bao)(bao)溫(wen)(wen)鋼(gang)(gang)管(guan)(guan)(guan)是影響節能(neng)(neng)的(de)(de)(de)(de)重(zhong)要因素，保(bao)(bao)(bao)(bao)溫(wen)(wen)鋼(gang)(gang)管(guan)(guan)(guan)的(de)(de)(de)(de)研制與應(ying)用(yong)越(yue)來(lai)越(yue)受(shou)到(dao)世(shi)界各國(guo)的(de)(de)(de)(de)普遍重(zhong)視。20世(shi)紀(ji)70年代后，國(guo)外普遍重(zhong)視保(bao)(bao)(bao)(bao)溫(wen)(wen)鋼(gang)(gang)管(guan)(guan)(guan)的(de)(de)(de)(de)和(he)應(ying)用(yong)，力求(qiu)大(da)幅度減少能(neng)(neng)源的(de)(de)(de)(de)消耗量(liang)(liang)，從(cong)(cong)(cong)而減少環境污染和(he)溫(wen)(wen)室(shi)效(xiao)應(ying)。國(guo)外保(bao)(bao)(bao)(bao)溫(wen)(wen)工業已經(jing)有(you)很(hen)長(chang)的(de)(de)(de)(de)歷史(shi)，而新型(xing)保(bao)(bao)(bao)(bao)溫(wen)(wen)材(cai)料(liao)也正在(zai)(zai)不(bu)斷地(di)涌現。 1980年以(yi)前，我(wo)國(guo)保(bao)(bao)(bao)(bao)溫(wen)(wen)鋼(gang)(gang)管(guan)(guan)(guan)的(de)(de)(de)(de)發(fa)(fa)展十分緩慢，為數不(bu)多的(de)(de)(de)(de)保(bao)(bao)(bao)(bao)溫(wen)(wen)廠(chang)只能(neng)(neng)少量(liang)(liang)地(di)下(xia)直(zhi)埋保(bao)(bao)(bao)(bao)溫(wen)(wen)鋼(gang)(gang)管(guan)(guan)(guan)，但中(zhong)國(guo)保(bao)(bao)(bao)(bao)溫(wen)(wen)工業經(jing)過(guo)30多年的(de)(de)(de)(de)努(nu)力，特(te)別(bie)是經(jing)過(guo)近(jin)10年的(de)(de)(de)(de)高速發(fa)(fa)展，不(bu)少產品從(cong)(cong)(cong)無到(dao)有(you)，從(cong)(cong)(cong)單一到(dao)多樣化，質(zhi)量(liang)(liang)從(cong)(cong)(cong)低到(dao)高，應(ying)用(yong)越(yue)來(lai)越(yue)普遍。聚(ju)氨(an)酯(zhi)材(cai)料(liao)是國(guo)際上最常用(yong)的(de)(de)(de)(de)保(bao)(bao)(bao)(bao)溫(wen)(wen)材(cai)料(liao)。硬(ying)質(zhi)聚(ju)氨(an)酯(zhi)具(ju)有(you)很(hen)多優(you)異性(xing)能(neng)(neng)，在(zai)(zai)歐(ou)美廣泛用(yong)于保(bao)(bao)(bao)(bao)溫(wen)(wen)隔熱領(ling)域。歐(ou)美等發(fa)(fa)達的(de)(de)(de)(de)保(bao)(bao)(bao)(bao)溫(wen)(wen)材(cai)料(liao)中(zhong)約有(you)49%為聚(ju)氨(an)酯(zhi)材(cai)料(liao)，而在(zai)(zai)中(zhong)國(guo)這一比例尚(shang)不(bu)足20%。因此，聚(ju)氨(an)酯(zhi)材(cai)料(liao)保(bao)(bao)(bao)(bao)溫(wen)(wen)鋼(gang)(gang)管(guan)(guan)(guan)在(zai)(zai)中(zhong)國(guo)還有(you)很(hen)大(da)的(de)(de)(de)(de)發(fa)(fa)展空間。
