其實不(bu)銹鋼(gang)異型管(guan)是除了圓管(guan)以(yi)外的(de)其他截(jie)面形狀的(de)鋼(gang)管(guan)的(de)總稱(cheng)，不(bu)銹鋼(gang)異型管(guan)非為焊接(jie)異型管(guan)和(he)無縫異型管(guan)。

材質

不銹鋼(gang)異(yi)型管的材(cai)質一般為(wei)304以上的材(cai)質為(wei)多，200、201、202材(cai)質硬度強(qiang)，成型難度大。使用價值比較(jiao)高。造價比其他的鋼(gang)管略微高一些。

加工方式

不(bu)銹鋼(gang)異(yi)型(xing)(xing)(xing)(xing)(xing)管(guan)(guan)(guan)(guan)加(jia)(jia)(jia)工(gong)(gong)分為一次(ci)(ci)成(cheng)型(xing)(xing)(xing)(xing)(xing)和多次(ci)(ci)成(cheng)型(xing)(xing)(xing)(xing)(xing)2種;一次(ci)(ci)成(cheng)型(xing)(xing)(xing)(xing)(xing)加(jia)(jia)(jia)工(gong)(gong)時(shi) 不(bu)銹鋼(gang)帶經過(guo) 焊管(guan)(guan)(guan)(guan)加(jia)(jia)(jia)工(gong)(gong)成(cheng)型(xing)(xing)(xing)(xing)(xing)生(sheng)產線(xian)，由組合磨具(ju)的(de)(de)擠壓變(bian)形(xing)焊接(jie)一次(ci)(ci)成(cheng)型(xing)(xing)(xing)(xing)(xing)出管(guan)(guan)(guan)(guan)達到設(she)定(ding)的(de)(de)異(yi)型(xing)(xing)(xing)(xing)(xing)管(guan)(guan)(guan)(guan)標準。多次(ci)(ci)成(cheng)型(xing)(xing)(xing)(xing)(xing)主要是2此成(cheng)型(xing)(xing)(xing)(xing)(xing)，是在(zai)圓管(guan)(guan)(guan)(guan)或者 方管(guan)(guan)(guan)(guan)的(de)(de)基礎上(shang)(shang)再次(ci)(ci)經過(guo) 機加(jia)(jia)(jia)工(gong)(gong)使進(jin)入管(guan)(guan)(guan)(guan)機械變(bian)形(xing)成(cheng)為設(she)定(ding)的(de)(de)異(yi)型(xing)(xing)(xing)(xing)(xing)管(guan)(guan)(guan)(guan)。在(zai)產品(pin)工(gong)(gong)藝(yi)(yi)質(zhi)量(liang)(liang)上(shang)(shang)前(qian)者一般要優于后者，但具(ju)體的(de)(de)質(zhi)量(liang)(liang)和工(gong)(gong)藝(yi)(yi)要求差異(yi)不(bu)會很大，有些(xie)不(bu)銹鋼(gang)異(yi)型(xing)(xing)(xing)(xing)(xing)管(guan)(guan)(guan)(guan)在(zai)截面異(yi)形(xing)復(fu)雜程(cheng)度較大而(er)無法一次(ci)(ci)成(cheng)型(xing)(xing)(xing)(xing)(xing)的(de)(de)情況下(xia)選(xuan)擇(ze)2次(ci)(ci)或者多次(ci)(ci)成(cheng)型(xing)(xing)(xing)(xing)(xing)也是目前(qian)我國(guo) 不(bu)銹鋼(gang)管(guan)(guan)(guan)(guan)加(jia)(jia)(jia)工(gong)(gong)技術和設(she)備還不(bu)能達到更加(jia)(jia)(jia)先進(jin)水(shui)平的(de)(de)恰當選(xuan)擇(ze)。

應用

不銹鋼(gang)異(yi)(yi)型管廣泛(fan)用于各種結(jie)構件、工具和機械(xie)零部件。與不銹鋼(gang)圓(yuan)管相比，不銹鋼(gang)異(yi)(yi)型管一般都有(you)較大的慣性矩和截(jie)面模數，有(you)較大的抗彎(wan)抗扭能力，可以(yi)大大減輕結(jie)構重量(liang)，節約鋼(gang)材(cai)。
