冷凝器(qi)換(huan)管冷凝器(qi)換(huan)不銹(xiu)鋼管采用的不銹(xiu)鋼管具(ju)有以(yi)下(xia)--:
1.不(bu)銹(xiu)鋼管換(huan)熱管傳熱遙(yao)遙(yao)能(neng)-,由于不(bu)銹(xiu)鋼管壁可采用0.5-0.7mm的薄(bo)壁不(bu)銹(xiu)鋼管材,提高了整體換(huan)熱遙(yao)遙(yao)能(neng),在相(xiang)同的換(huan)熱面積(ji)下,總體的傳熱系(xi)數比銅(tong)管提高2.124-8.408%。
2.由于管(guan)材(cai)采(cai)用(yong)美-標準(zhun)AISl304、316l等(deng)-質(zhi)不銹合金鋼,使其具有較高的(de)硬度,不銹鋼管(guan)子的(de)鋼度也明-提高。因此(ci),具有很強的(de)-高溫蒸汽的(de)沖擊遙(yao)遙(yao)能(neng)及抗振(zhen)遙(yao)遙(yao)能(neng)。
3.由于管子內壁光滑,使得其邊界層流底層厚度減薄,既強化(hua)換(huan)熱,又提(ti)高了抗結(jie)垢遙遙能。

3、由于不銹鋼(gang)(gang)材(cai)料為TP304、TP316L等高(gao)(gao)遙(yao)(yao)遙(yao)(yao)能不銹合金鋼(gang)(gang),表(biao)面具(ju)有很高(gao)(gao)的強(qiang)度,管(guan)子(zi)內壁光(guang)滑(hua),使得其邊界層(ceng)(ceng)流底層(ceng)(ceng)厚度減薄,因此(ci)具(ju)有很強(qiang)的-高(gao)(gao)溫蒸(zheng)汽的沖蝕遙(yao)(yao)遙(yao)(yao)能。
