異(yi)型(xing)無縫鋼管廣(guang)泛用(yong)于各種結構件(jian)、工(gong)具和(he)機(ji)械(xie)零部件(jian)。和(he)圓管相(xiang)比，異(yi)型(xing)管一(yi)般都有(you)較大的(de)(de)慣性矩和(he)截面模數，有(you)較大的(de)(de)抗(kang)彎抗(kang)扭能力，可以大大減輕結構重量，節約鋼材。

異(yi)型(xing)管(guan)(guan)(guan)一般是根據斷截面來區(qu)分(fen)(fen)的，按材(cai)料(liao)來說又可分(fen)(fen)為無縫鋼管(guan)(guan)(guan)異(yi)型(xing)管(guan)(guan)(guan)，鋁(lv)合金異(yi)型(xing)管(guan)(guan)(guan)，塑料(liao)異(yi)型(xing)管(guan)(guan)(guan)。下(xia)面主要介紹一下(xia)鋼管(guan)(guan)(guan)異(yi)型(xing)管(guan)(guan)(guan)。

鋼(gang)(gang)管(guan)(guan)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)管(guan)(guan)可(ke)分為橢(tuo)圓形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、三角形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、六角形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、菱形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、八(ba)角形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、半圓形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)圓，不等(deng)邊(bian)六角形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、五瓣梅花形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、雙(shuang)凸形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、雙(shuang)凹形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、瓜(gua)子形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、圓錐形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、波(bo)紋形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、燈籠型(xing)(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)。
