異型(xing)(xing)無縫鋼(gang)管(guan)廣泛用于各種(zhong)結構(gou)件(jian)、工具和機械零部件(jian)。和圓(yuan)管(guan)相比，異型(xing)(xing)管(guan)一(yi)般都有(you)(you)較(jiao)大的慣性矩和截面模數，有(you)(you)較(jiao)大的抗彎抗扭能力，可以大大減輕結構(gou)重量，節約(yue)鋼(gang)材。

異(yi)型(xing)管(guan)(guan)(guan)一(yi)般是根據斷截面來區分(fen)的，按材料(liao)來說(shuo)又可(ke)分(fen)為無縫鋼(gang)管(guan)(guan)(guan)異(yi)型(xing)管(guan)(guan)(guan)，鋁(lv)合金(jin)異(yi)型(xing)管(guan)(guan)(guan)，塑料(liao)異(yi)型(xing)管(guan)(guan)(guan)。下(xia)面主(zhu)要介紹一(yi)下(xia)鋼(gang)管(guan)(guan)(guan)異(yi)型(xing)管(guan)(guan)(guan)。

鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)異(yi)(yi)型(xing)(xing)管(guan)(guan)(guan)(guan)(guan)可分(fen)為橢圓(yuan)形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、三角(jiao)(jiao)形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、六角(jiao)(jiao)形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、菱(ling)形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、八角(jiao)(jiao)形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、半圓(yuan)形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)圓(yuan)，不等邊六角(jiao)(jiao)形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、五瓣梅花形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、雙(shuang)凸形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、雙(shuang)凹形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、瓜子形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、圓(yuan)錐形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、波紋形(xing)(xing)異(yi)(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)、燈籠型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)。
