厚壁無縫鋼管分類：
熱軋厚壁無縫鋼管、冷軋厚(hou)(hou)壁無縫(feng)鋼管(guan)、冷拔厚(hou)(hou)壁無縫(feng)鋼管(guan)、擠壓厚(hou)(hou)壁無縫(feng)鋼管(guan)、頂管(guan)
結構(gou)用(yong)不銹(xiu)鋼無(wu)縫鋼管(guan)(guan)(guan)(GB/T14975-2002)是用(yong)于一(yi)般(ban)結構(gou)和(he)機(ji)械結構(gou)的無(wu)縫鋼管(guan)(guan)(guan)，廣泛用(yong)于化工、 石油、輕(qing)紡、 醫療、食品(pin)、 機(ji)械等工業的耐腐蝕(shi)管(guan)(guan)(guan)道和(he)結構(gou)件(jian)及零件(jian)的不銹(xiu)鋼制成的熱軋(擠、擴)和(he)冷拔(軋)無(wu)縫鋼管(guan)(guan)(guan)。
異(yi)型(xing)(xing)無(wu)(wu)縫(feng)(feng)(feng)鋼管是除了圓管以(yi)外的其(qi)他截(jie)面形狀(zhuang)的無(wu)(wu)縫(feng)(feng)(feng)鋼管的總(zong)稱。按鋼管截(jie)面形狀(zhuang)尺寸的不同又可分(fen)為(wei)等壁厚異(yi)型(xing)(xing)無(wu)(wu)縫(feng)(feng)(feng)鋼管(代(dai)號為(wei)D)、不等壁厚異(yi)型(xing)(xing)無(wu)(wu)縫(feng)(feng)(feng)鋼管(代(dai)號為(wei)BD)、變直徑異(yi)型(xing)(xing)無(wu)(wu)縫(feng)(feng)(feng)鋼管(代(dai)號為(wei)BJ)。異(yi)型(xing)(xing)無(wu)(wu)縫(feng)(feng)(feng)鋼管廣泛(fan)用于(yu)各(ge)種(zhong)結(jie)構件、工具和機(ji)械(xie)零(ling)部件。和圓管相比，異(yi)型(xing)(xing)管一般都有較大(da)的慣性矩和截(jie)面模數(shu)，有較大(da)的抗(kang)彎抗(kang)扭能(neng)力，可以(yi)大(da)大(da)減輕結(jie)構重量，節約鋼材。
厚壁無縫鋼(gang)管按(an)材質分類：
鋼管的材(cai)質為(wei)(wei)10#、20#、35#、45#、16Mn、27SiMn、40Cr、12Cr1MoV、10CrMo910、15CrMo、35CrMo、45Mn2等，稱為(wei)(wei)普通厚壁無縫(feng)鋼管和(he)合金鋼管。
