冷拔六角鋼管是無縫管的一種，其特性要比一般的無縫管高許多，由于這類無縫鋼管里邊含Cr比較多，其耐熱、耐寒、抗腐蝕的特性是別的無縫管不如的，因此 合金鋼管在原油、化工廠、電力工程、加熱爐等領域的主要用途較為普遍。~冷拔六角鋼管包括原素有硅、錳、鉻、鎳、鉬、鎢、釩、鈦、鈮、鋯、鈷、鋁、銅、硼、希土等。冷拔六角鋼管(SeamlessSteelTube)具備空心橫(heng)(heng)截(jie)面(mian)(mian)、附近沒有接縫(feng)處的條形不(bu)(bu)銹鋼(gang)(gang)板(ban)材(cai)。無(wu)縫(feng)鋼(gang)(gang)管(guan)(guan)具備空心橫(heng)(heng)截(jie)面(mian)(mian)，很多作為運(yun)(yun)輸(shu)液(ye)體的管(guan)(guan)路，如(ru)運(yun)(yun)輸(shu)原油、燃氣、液(ye)化氣、水及一(yi)些固態(tai)原材(cai)料的管(guan)(guan)路等。鋁合金無(wu)縫(feng)管(guan)(guan)與園鋼(gang)(gang)等實(shi)芯不(bu)(bu)銹鋼(gang)(gang)板(ban)材(cai)對比，在(zai)抗彎強度抗扭抗壓強度同樣時，凈重比較(jiao)輕，是(shi)一(yi)種經濟發展(zhan)橫(heng)(heng)截(jie)面(mian)(mian)不(bu)(bu)銹鋼(gang)(gang)板(ban)材(cai)，普遍用以(yi)加工(gong)制造(zao)零部(bu)件(jian)和機械零件(jian)，如(ru)原油運(yun)(yun)輸(shu)、樓梯護(hu)欄(lan)、自行車車架及其建(jian)筑工(gong)程施工(gong)選用的鋼(gang)(gang)鋼(gang)(gang)管(guan)(guan)腳手架等。
