無縫鋼管

無(wu)(wu)縫鋼(gang)(gang)管(guan)用(yong)(yong)(yong)(yong)途很廣泛。一般用(yong)(yong)(yong)(yong)途的(de)(de)無(wu)(wu)縫鋼(gang)(gang)管(guan)由普通的(de)(de)碳素結(jie)構(gou)鋼(gang)(gang)、低合金(jin)結(jie)構(gou)鋼(gang)(gang)或合金(jin)結(jie)構(gou)鋼(gang)(gang)軋(ya)制，產量(liang)最多(duo)，主要(yao)用(yong)(yong)(yong)(yong)作輸(shu)送(song)流(liu)體(ti)(ti)的(de)(de)管(guan)道(dao)或結(jie)構(gou)零件(jian)。.2、根據用(yong)(yong)(yong)(yong)途不同分(fen)三類(lei)供(gong)(gong)應(ying)：a、按化學成分(fen)和機(ji)械性(xing)能供(gong)(gong)應(ying)；b、按機(ji)械性(xing)能供(gong)(gong)應(ying)；c、按水(shui)(shui)壓試驗(yan)供(gong)(gong)應(ying)。按a、b類(lei)供(gong)(gong)應(ying)的(de)(de)鋼(gang)(gang)管(guan)，如(ru)用(yong)(yong)(yong)(yong)于承受液體(ti)(ti)壓力，也要(yao)進行水(shui)(shui)壓試驗(yan)。3、專門用(yong)(yong)(yong)(yong)途的(de)(de)無(wu)(wu)縫管(guan)有鍋(guo)爐(lu)用(yong)(yong)(yong)(yong)無(wu)(wu)縫管(guan)、化工電力用(yong)(yong)(yong)(yong)，地質用(yong)(yong)(yong)(yong)無(wu)(wu)縫鋼(gang)(gang)管(guan)及石油(you)用(yong)(yong)(yong)(yong)無(wu)(wu)縫管(guan)等多(duo)種。

無(wu)縫(feng)鋼(gang)管(guan)(guan)具(ju)有中空(kong)截(jie)面(mian)(mian)，大量用(yong)作輸(shu)送流體(ti)的(de)管(guan)(guan)道(dao)，如輸(shu)送石油、天然氣(qi)、煤氣(qi)、水及(ji)某些固體(ti)物料的(de)管(guan)(guan)道(dao)等(deng)。鋼(gang)管(guan)(guan)與圓鋼(gang)等(deng)實心鋼(gang)材(cai)相比，在抗彎抗扭(niu)強度相同(tong)時，重量較輕(qing)，是一種經濟截(jie)面(mian)(mian)鋼(gang)材(cai)。

廣泛用(yong)于制造(zao)結構件(jian)(jian)和(he)機械零件(jian)(jian)，如(ru)石油鉆桿、汽車傳動(dong)軸、自行車架以(yi)及建(jian)筑施工(gong)中用(yong)的鋼腳手(shou)架等用(yong)鋼管制造(zao)環形(xing)零件(jian)(jian)，可提高(gao)材(cai)料利(li)用(yong)率，簡化(hua)制造(zao)工(gong)序，節(jie)約(yue)材(cai)料和(he)加(jia)工(gong)工(gong)時(shi)，已(yi)廣泛用(yong)鋼管來制造(zao)。
