　　熱軋(ya)厚壁(bi)無(wu)縫鋼管、冷軋(ya)厚壁(bi)無(wu)縫鋼管、冷拔(ba)厚壁(bi)無(wu)縫鋼管、擠(ji)壓厚壁(bi)無(wu)縫鋼管、頂(ding)管

　　結(jie)構用不銹(xiu)鋼(gang)無(wu)縫(feng)鋼(gang)管(guan)(GB/T14975-2002)是用于一般(ban)結(jie)構和機械結(jie)構的(de)無(wu)縫(feng)鋼(gang)管(guan)，廣泛(fan)用于化(hua)工、石油、輕紡、醫療、食品、機械等工業的(de)耐腐蝕管(guan)道和結(jie)構件及零件的(de)不銹(xiu)鋼(gang)制成的(de)熱軋(擠、擴)和冷拔(ba)(軋)無(wu)縫(feng)鋼(gang)管(guan)。

　　流(liu)體輸送用(yong)(yong)不(bu)銹(xiu)鋼無縫鋼管(guan)(GB/T14976-2002)是(shi)用(yong)(yong)于輸送水、油、氣等流(liu)體的一般無縫鋼管(guan)，通常是(shi)用(yong)(yong)不(bu)銹(xiu)鋼制成的熱(re)軋(擠、擴)和冷拔(軋)無縫鋼管(guan)。

　　異(yi)(yi)(yi)(yi)型(xing)無(wu)縫鋼管(guan)(guan)(guan)是除了(le)圓(yuan)管(guan)(guan)(guan)以外(wai)的(de)其他截面形(xing)狀的(de)無(wu)縫鋼管(guan)(guan)(guan)的(de)總稱(cheng)。按(an)鋼管(guan)(guan)(guan)截面形(xing)狀尺寸的(de)不同(tong)又可分為等壁(bi)厚異(yi)(yi)(yi)(yi)型(xing)無(wu)縫鋼管(guan)(guan)(guan)(代(dai)號為D)、不等壁(bi)厚異(yi)(yi)(yi)(yi)型(xing)無(wu)縫鋼管(guan)(guan)(guan)(代(dai)號為BD)、變直徑(jing)異(yi)(yi)(yi)(yi)型(xing)無(wu)縫鋼管(guan)(guan)(guan)(代(dai)號為BJ)。異(yi)(yi)(yi)(yi)型(xing)無(wu)縫鋼管(guan)(guan)(guan)廣(guang)泛用于各(ge)種(zhong)結構件(jian)、工(gong)具和(he)(he)機械(xie)零部件(jian)。和(he)(he)圓(yuan)管(guan)(guan)(guan)相比，異(yi)(yi)(yi)(yi)型(xing)管(guan)(guan)(guan)一(yi)般都有(you)較大(da)(da)的(de)慣性(xing)矩和(he)(he)截面模數，有(you)較大(da)(da)的(de)抗(kang)彎抗(kang)扭(niu)能力，可以大(da)(da)大(da)(da)減輕(qing)結構重量，節約鋼材。
