寶(bao)雞鈦廠(chang)家對比了不銹鋼管(guan)和鈦管(guan)的區別

鈦(tai)管(guan)(guan)(guan)質(zhi)量輕，強度(du)高，機(ji)械性能優(you)越。它廣泛(fan)應用(yong)(yong)于(yu)熱(re)交(jiao)換(huan)(huan)設(she)備，如(ru)(ru)列(lie)管(guan)(guan)(guan)式(shi)(shi)換(huan)(huan)熱(re)器(qi)(qi)(qi)、盤管(guan)(guan)(guan)式(shi)(shi)換(huan)(huan)熱(re)器(qi)(qi)(qi)、蛇形(xing)管(guan)(guan)(guan)式(shi)(shi)換(huan)(huan)熱(re)器(qi)(qi)(qi)、冷(leng)凝器(qi)(qi)(qi)、蒸(zheng)發器(qi)(qi)(qi)和輸送管(guan)(guan)(guan)道等(deng)。目前，很多(duo)核(he)電(dian)工業(ye)(ye)把(ba)鈦(tai)管(guan)(guan)(guan)作為(wei)其機(ji)組標準(zhun)用(yong)(yong)管(guan)(guan)(guan)。 鈦(tai)管(guan)(guan)(guan)質(zhi)量輕，強度(du)高，機(ji)械性能優(you)越。它廣泛(fan)應用(yong)(yong)于(yu)熱(re)交(jiao)換(huan)(huan)設(she)備，如(ru)(ru)列(lie)管(guan)(guan)(guan)式(shi)(shi)換(huan)(huan)熱(re)器(qi)(qi)(qi)、盤管(guan)(guan)(guan)式(shi)(shi)換(huan)(huan)熱(re)器(qi)(qi)(qi)、蛇形(xing)管(guan)(guan)(guan)式(shi)(shi)換(huan)(huan)熱(re)器(qi)(qi)(qi)、冷(leng)凝器(qi)(qi)(qi)、蒸(zheng)發器(qi)(qi)(qi)和輸送管(guan)(guan)(guan)道等(deng)。目前，很多(duo)核(he)電(dian)工業(ye)(ye)把(ba)鈦(tai)管(guan)(guan)(guan)作為(wei)其機(ji)組標準(zhun)用(yong)(yong)管(guan)(guan)(guan)。

鈦管(guan)按照使用要求和性(xing)能的不同執行兩個國(guo)家標準：GB/T3624-1995　GB/T3625-1995

不(bu)銹鋼管(guan)是一種(zhong)中空(kong)的(de)長(chang)條鋼材，大量用作輸(shu)送流(liu)體的(de)管(guan)道，如石油、天燃氣、水、煤氣、蒸氣等，另外，在搞彎、抗扭強度相同時，重(zhong)量較(jiao)輕，所以也(ye)廣泛用于制造機械(xie)零件和工程結構。也(ye)常(chang)用作生產(chan)各種(zhong)常(chang)規武器、槍(qiang)管(guan)、炮彈等。

不(bu)(bu)銹鋼管(guan)(guan)(guan)(guan)(guan)的分類：鋼管(guan)(guan)(guan)(guan)(guan)分無(wu)縫鋼管(guan)(guan)(guan)(guan)(guan)和焊(han)接鋼管(guan)(guan)(guan)(guan)(guan)（有縫管(guan)(guan)(guan)(guan)(guan)）兩(liang)大類。按斷面(mian)形(xing)(xing)狀又可分為(wei)圓(yuan)管(guan)(guan)(guan)(guan)(guan)和異形(xing)(xing)管(guan)(guan)(guan)(guan)(guan)，廣泛(fan)應用的是圓(yuan)形(xing)(xing)鋼管(guan)(guan)(guan)(guan)(guan)，但(dan)也有一(yi)些方(fang)形(xing)(xing)、矩形(xing)(xing)、半圓(yuan)形(xing)(xing)、六角形(xing)(xing)、等(deng)邊三角形(xing)(xing)、八角形(xing)(xing)等(deng)異形(xing)(xing)鋼管(guan)(guan)(guan)(guan)(guan)。對于承受流體壓(ya)(ya)力的鋼管(guan)(guan)(guan)(guan)(guan)都要(yao)(yao)進行液壓(ya)(ya)試(shi)(shi)驗(yan)來檢驗(yan)其耐(nai)壓(ya)(ya)能(neng)力和質量，在規(gui)定的壓(ya)(ya)力下不(bu)(bu)發生泄漏、浸濕或膨脹(zhang)為(wei)合格，有些鋼管(guan)(guan)(guan)(guan)(guan)還要(yao)(yao)根(gen)據標準(zhun)或需(xu)方(fang)要(yao)(yao)求進行卷邊試(shi)(shi)驗(yan)、擴口試(shi)(shi)驗(yan)、壓(ya)(ya)扁試(shi)(shi)驗(yan)等(deng)。

工業純鈦：工業純鈦的雜(za)質(zhi)含量較(jiao)(jiao)化(hua)學(xue)純鈦要(yao)多，因此其強(qiang)度、硬度也稍高，其力學(xue)性(xing)(xing)(xing)能及化(hua)學(xue)性(xing)(xing)(xing)能與不銹(xiu)鋼相近，比起鈦合金純鈦強(qiang)度較(jiao)(jiao)好，在抗氧(yang)化(hua)性(xing)(xing)(xing)方面優于奧氏體不銹(xiu)鋼，但耐熱性(xing)(xing)(xing)較(jiao)(jiao)差(cha)，TA1、TA2、TA3依(yi)次雜(za)質(zhi)含量增高，機(ji)械(xie)強(qiang)度、硬度依(yi)次增強(qiang)，但塑性(xing)(xing)(xing)韌性(xing)(xing)(xing)依(yi)次下降。
