換熱器(qi)中(zhong),內嵌管板(ban)是一(yi)種(zhong)重要的組成部件,現有的管板(ban)兼做法蘭的鈦換熱器(qi)存在以下(xia)不(bu)足:

　　一(yi)、由(you)于鈦(tai)(tai)材(cai)與其他材(cai)質無法(fa)焊接的(de)特性,法(fa)蘭和管板都需要(yao)鈦(tai)(tai)材(cai),因此,較(jiao)大的(de)增(zeng)加了鈦(tai)(tai)材(cai)使用(yong)量。

　　二、由于(yu)鈦材(cai)厚度對設(she)計壓力(li)影(ying)響(xiang)較大,因此,當設(she)計壓力(li)增加(jia)時,法蘭和管板(ban)厚度將(jiang)同步增加(jia)。

　　為(wei)此研(yan)究人員(yuan)研(yan)究出(chu)了(le)一種適應(ying)不同(tong)設計壓力,同(tong)時可以采用襯環活套法蘭結構的(de)內嵌管鈦換熱器。
