螺栓球(qiu)網架(jia)配件鋼管的介(jie)紹
具有空(kong)心截面,其(qi)長度遠大于直徑或周長的鋼(gang)(gang)(gang)材。按(an)(an)(an)截面形(xing)(xing)狀分(fen)為圓形(xing)(xing)、方(fang)形(xing)(xing)、矩形(xing)(xing)和異形(xing)(xing)鋼(gang)(gang)(gang)管(guan)(guan);按(an)(an)(an)材質(zhi)(zhi)分(fen)為碳素結構鋼(gang)(gang)(gang)鋼(gang)(gang)(gang)管(guan)(guan)、低合(he)(he)金結構鋼(gang)(gang)(gang)鋼(gang)(gang)(gang)管(guan)(guan)、合(he)(he)金鋼(gang)(gang)(gang)鋼(gang)(gang)(gang)管(guan)(guan)和復合(he)(he)鋼(gang)(gang)(gang)管(guan)(guan);按(an)(an)(an)用(yong)(yong)途分(fen)為輸送管(guan)(guan)道(dao)用(yong)(yong)、工程結構用(yong)(yong)、熱工設備(bei)用(yong)(yong)、石油化工工業用(yong)(yong)、機械制造用(yong)(yong)、地質(zhi)(zhi)鉆探(tan)用(yong)(yong)、高壓設備(bei)用(yong)(yong)鋼(gang)(gang)(gang)管(guan)(guan)等;按(an)(an)(an)生(sheng)產工藝(yi)分(fen)為無縫鋼(gang)(gang)(gang)管(guan)(guan)和焊接鋼(gang)(gang)(gang)管(guan)(guan),其(qi)中無縫鋼(gang)(gang)(gang)管(guan)(guan)又分(fen)熱軋和冷軋(拔(ba))兩種,焊接鋼(gang)(gang)(gang)管(guan)(guan)又分(fen)直縫焊接鋼(gang)(gang)(gang)管(guan)(guan)和螺旋(xuan)縫焊接鋼(gang)(gang)(gang)管(guan)(guan)。
鋼管不僅用于輸送流體和(he)粉狀固體、交換(huan)熱能、制(zhi)造(zao)機械(xie)(xie)零件和(he)容器,它還是一(yi)種經(jing)濟鋼材。用鋼管制(zhi)造(zao)建筑結(jie)構網架、支柱和(he)機械(xie)(xie)支架,可(ke)以減 輕重(zhong)量,節省(sheng)金屬20~40%,而且(qie)可(ke)實現工廠(chang)化(hua)機械(xie)(xie)化(hua)施(shi)工。用鋼管制(zhi)造(zao)公路橋梁(liang)不但可(ke)節省(sheng)鋼材、簡化(hua)施(shi)工,而且(qie)可(ke)大大減少涂(tu)保護層(ceng)的(de)面積,節約投資和(he)維護費(fei)用。
