我公司生產的簿壁304/316l不(bu)銹鋼光(guang)管具(ju)有以下：

1.凝(ning)汽(qi)器(qi)-汽(qi)輪機凝(ning)汽(qi)器(qi)304/316l不銹鋼(gang)管(guan)換(huan)熱(re)管(guan)熱(re)能，由于(yu)不銹鋼(gang)管(guan)壁可采用0.5-0.7mm的薄壁不銹鋼(gang)管(guan)材，提了整體(ti)換(huan)熱(re)能，在相(xiang)同的換(huan)熱(re)面積下，總體(ti)的304/316l不銹鋼(gang)管(guan)換(huan)熱(re)管(guan)熱(re)系數(shu)比銅(tong)管(guan)提2.124-8.408％。

2.由于304/316l不(bu)(bu)銹鋼管(guan)換熱管(guan)材質采用美標準AISl304、316l等不(bu)(bu)銹合金鋼，使其具有較的硬度，不(bu)(bu)銹鋼管(guan)子的鋼度也明提。因(yin)此，具有很強的溫蒸汽的沖(chong)擊能及抗(kang)振能。

3.由于304/316不銹鋼管子內壁光滑，使得(de)其邊界層流底層厚度(du)減(jian)薄，既強化換(huan)熱，又提了抗結垢能(neng)。

4.裝凝(ning)汽(qi)器-汽(qi)輪機凝(ning)汽(qi)器304/316l不(bu)銹(xiu)鋼管(guan)(guan)換(huan)熱管(guan)(guan)工藝能，采用的(de)(de)脹管(guan)(guan)工藝，304/316l不(bu)銹(xiu)鋼管(guan)(guan)換(huan)熱管(guan)(guan)外徑公差(cha)與銅管(guan)(guan)致，不(bu)需改變(bian)管(guan)(guan)板孔的(de)(de)加(jia)工公差(cha)，利于現(xian)場直(zhi)接選用，別方便(bian)機的(de)(de)304/316l不(bu)銹(xiu)鋼管(guan)(guan)換(huan)熱管(guan)(guan)換(huan)管(guan)(guan)束改造。

5.304/316l不(bu)銹鋼管換熱管經濟，在同等(deng)換熱面(mian)積下(xia)，不(bu)銹鋼管的本(ben)約為銅管本(ben)的80％左右，并可直接進行換管束(shu)改造(zao)。

6.為了消(xiao)除304/316l不銹鋼管(guan)換熱管(guan)遙應(ying)力，在保護氣體以1050℃溫進行熱處理。

7.所有304/316l不銹鋼管換熱管鋼管均采用壓差法進行泄查，氣壓試驗至1.0Mpa，5分鐘壓降。
