異型無縫鋼管(guan)廣泛用于各種(zhong)結構件、工(gong)具和(he)(he)機械零部件。和(he)(he)圓管(guan)相比，異型管(guan)一般都有(you)較(jiao)大(da)(da)的慣性矩(ju)和(he)(he)截(jie)面模(mo)數，有(you)較(jiao)大(da)(da)的抗彎(wan)抗扭能(neng)力，可以大(da)(da)大(da)(da)減(jian)輕結構重量，節約鋼材。

異型(xing)(xing)管(guan)(guan)一(yi)般是根(gen)據斷截面來區分(fen)的，按材(cai)料來說又可分(fen)為無縫鋼(gang)管(guan)(guan)異型(xing)(xing)管(guan)(guan)，鋁合金異型(xing)(xing)管(guan)(guan)，塑料異型(xing)(xing)管(guan)(guan)。下(xia)面主要介紹一(yi)下(xia)鋼(gang)管(guan)(guan)異型(xing)(xing)管(guan)(guan)。

鋼(gang)(gang)管(guan)(guan)(guan)(guan)異(yi)型(xing)(xing)管(guan)(guan)(guan)(guan)可分為橢(tuo)圓(yuan)形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、三角形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、六(liu)角形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、菱形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、八角形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、半圓(yuan)形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)圓(yuan)，不等邊六(liu)角形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、五瓣梅花形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、雙凸形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、雙凹形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、瓜子(zi)形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、圓(yuan)錐形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、波(bo)紋形(xing)(xing)(xing)(xing)(xing)異(yi)型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、燈籠型(xing)(xing)鋼(gang)(gang)管(guan)(guan)(guan)(guan)。
