異型無縫鋼管廣泛用于各(ge)種結構(gou)件、工具和(he)機械零部件。和(he)圓管相比(bi)，異型管一(yi)般都有較大的(de)慣性矩(ju)和(he)截(jie)面模數，有較大的(de)抗(kang)彎抗(kang)扭能力，可以大大減輕結構(gou)重量，節約鋼材。

異(yi)(yi)型管(guan)(guan)(guan)(guan)一般是根據斷截面(mian)(mian)來區分的，按材(cai)料來說又(you)可分為無縫鋼(gang)管(guan)(guan)(guan)(guan)異(yi)(yi)型管(guan)(guan)(guan)(guan)，鋁合金異(yi)(yi)型管(guan)(guan)(guan)(guan)，塑料異(yi)(yi)型管(guan)(guan)(guan)(guan)。下面(mian)(mian)主要(yao)介紹一下鋼(gang)管(guan)(guan)(guan)(guan)異(yi)(yi)型管(guan)(guan)(guan)(guan)。

鋼(gang)(gang)管(guan)(guan)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)管(guan)(guan)可分為(wei)橢(tuo)圓(yuan)形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、三角(jiao)形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、六角(jiao)形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、菱形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、八(ba)角(jiao)形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、半圓(yuan)形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)圓(yuan)，不等邊六角(jiao)形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、五(wu)瓣梅(mei)花形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、雙凸(tu)形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、雙凹形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、瓜子形(xing)(xing)異(yi)(yi)(yi)(yi)型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)、圓(yuan)錐形(xing)(xing)異(yi)(yi)(yi)(yi)型(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)鋼(gang)(gang)管(guan)(guan)、燈籠型(xing)(xing)(xing)(xing)鋼(gang)(gang)管(guan)(guan)。
