異型無縫鋼管廣泛用于各種結(jie)構(gou)(gou)件(jian)、工具和(he)(he)機械零部件(jian)。和(he)(he)圓管相比，異型管一般都(dou)有(you)較大的(de)慣性矩和(he)(he)截面模數，有(you)較大的(de)抗(kang)彎(wan)抗(kang)扭能力，可以大大減輕(qing)結(jie)構(gou)(gou)重量，節約鋼材。

異(yi)型(xing)管(guan)一(yi)般是根(gen)據斷截面來(lai)區分(fen)的(de)，按(an)材料(liao)來(lai)說又(you)可分(fen)為無縫鋼管(guan)異(yi)型(xing)管(guan)，鋁(lv)合金異(yi)型(xing)管(guan)，塑料(liao)異(yi)型(xing)管(guan)。下面主(zhu)要介紹一(yi)下鋼管(guan)異(yi)型(xing)管(guan)。

鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)異(yi)型(xing)(xing)(xing)管(guan)(guan)(guan)可分為橢圓形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、三角形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、六角形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、菱形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、八角形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、半圓形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)圓，不(bu)等邊六角形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、五瓣(ban)梅花形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、雙凸形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、雙凹(ao)形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、瓜子形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、圓錐形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、波(bo)紋形(xing)(xing)異(yi)型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)、燈籠型(xing)(xing)(xing)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)。
