碳化復(fu)合管(guan)換熱(re)器泄漏檢(jian)(jian)(jian)驗(yan)(yan)的(de)(de)基本原理是識別泄漏點(dian)和定位泄漏點(dian)，或(huo)者測量通過泄漏點(dian)流體(ti)的(de)(de)流量或(huo)試驗(yan)(yan)介(jie)質(zhi)的(de)(de)流量，這些可以反(fan)映出(chu)流量、壓力(li)降或(huo)真(zhen)空(kong)度的(de)(de)降低。碳化復(fu)合管(guan)換熱(re)器主要的(de)(de)泄漏檢(jian)(jian)(jian)驗(yan)(yan)的(de)(de)方法(fa)有超聲波檢(jian)(jian)(jian)驗(yan)(yan)、氣(qi)泡檢(jian)(jian)(jian)驗(yan)(yan)（直接壓力(li)技(ji)(ji)術或(huo)浸漬技(ji)(ji)術，或(huo)真(zhen)空(kong)容器方法(fa)）、氣(qi)體(ti)泄漏試驗(yan)(yan)、壓力(li)變(bian)化檢(jian)(jian)(jian)驗(yan)(yan)、鹵素真(zhen)空(kong)管(guan)檢(jian)(jian)(jian)測儀探測檢(jian)(jian)(jian)驗(yan)(yan)、氦質(zhi)譜儀（檢(jian)(jian)(jian)漏頭）探測技(ji)(ji)術等。

碳化(hua)復合管換(huan)熱器的換(huan)墊(dian)和清垢操作(zuo)

1、換(huan)(huan)墊(dian)(dian)(dian) ?檢查換(huan)(huan)熱(re)機(ji)組管箱(xiang)絲堵(du)墊(dian)(dian)(dian)片泄(xie)(xie)漏情(qing)況，泄(xie)(xie)漏時(shi)刻采(cai)用把緊(jin)絲堵(du)或更換(huan)(huan)墊(dian)(dian)(dian)片消漏。墊(dian)(dian)(dian)片更換(huan)(huan)，應根(gen)據介質(zhi)選(xuan)用合適的墊(dian)(dian)(dian)片，碳化復合管換(huan)(huan)熱(re)器(qi)生產，一般選(xuan)用08鋼墊(dian)(dian)(dian)、紫銅墊(dian)(dian)(dian)或不(bu)銹(xiu)鋼墊(dian)(dian)(dian)。更換(huan)(huan)時(shi)，應清除(chu)換(huan)(huan)熱(re)機(ji)組墊(dian)(dian)(dian)片槽中(zhong)的雜物和消除(chu)墊(dian)(dian)(dian)片槽缺陷。

2、清(qing)(qing)垢 ?換(huan)(huan)熱(re)機(ji)(ji)組(zu)經(jing)過使用(yong)后，碳化(hua)復合管(guan)換(huan)(huan)熱(re)器，會在(zai)干式(shi)(shi)換(huan)(huan)熱(re)機(ji)(ji)組(zu)翅管(guan)表面積(ji)垢或在(zai)濕式(shi)(shi)換(huan)(huan)熱(re)機(ji)(ji)組(zu)翅管(guan)表面生長綠(lv)藻，影響冷卻效(xiao)果(guo)，應清(qing)(qing)除干凈(jing)。清(qing)(qing)垢可采用(yong)人(ren)工機(ji)(ji)械除垢、壓力水除垢和化(hua)學除垢。當(dang)采用(yong)壓力水除垢時(shi)，用(yong)防(fang)止換(huan)(huan)熱(re)機(ji)(ji)組(zu)翅片倒伏。

碳(tan)(tan)化復合(he)(he)管(guan)換熱器(qi)(qi)換熱端部盲板采(cai)用大(da)螺(luo)(luo)紋(wen)結(jie)構(gou)。通過與管(guan)箱部螺(luo)(luo)紋(wen)連接(jie)，碳(tan)(tan)化復合(he)(he)管(guan)換熱器(qi)(qi)采(cai)購，將巨大(da)的(de)(de)(de)介質(zhi)壓(ya)力(li)傳(chuan)遞至管(guan)箱，碳(tan)(tan)化復合(he)(he)管(guan)換熱器(qi)(qi)價格低，避免了(le)(le)傳(chuan)統(tong)法蘭連接(jie)結(jie)構(gou)中高(gao)溫、高(gao)壓(ya)工況(kuang)需采(cai)用法蘭、大(da)螺(luo)(luo)柱的(de)(de)(de)問(wen)題(ti)，大(da)大(da)減低了(le)(le)材料使用量；且(qie)因采(cai)用承受(shou)介質(zhi)壓(ya)力(li)部件與提供密封所需要(yao)壓(ya)緊力(li)的(de)(de)(de)部件相分離的(de)(de)(de)設計結(jie)構(gou)，使得管(guan)程(cheng)密封可靠性大(da)大(da)提高(gao)，大(da)螺(luo)(luo)紋(wen)連接(jie)結(jie)構(gou)是(shi)其(qi)(qi)區別于其(qi)(qi)他類型熱交(jiao)(jiao)換器(qi)(qi)明顯的(de)(de)(de)標(biao)志(zhi)。但是(shi)，熱交(jiao)(jiao)換器(qi)(qi)大(da)螺(luo)(luo)紋(wen)拆(chai)裝也是(shi)煉油(you)廠檢修(xiu)過程(cheng)中遇到的(de)(de)(de)一個(ge)非常(chang)棘手的(de)(de)(de)問(wen)題(ti)，常(chang)有大(da)螺(luo)(luo)紋(wen)拆(chai)裝過程(cheng)中發生螺(luo)(luo)紋(wen)損傷及咬死的(de)(de)(de)現象(xiang)。目前熱交(jiao)(jiao)換器(qi)(qi)使用的(de)(de)(de)裝拆(chai)螺(luo)(luo)紋(wen)工裝有杠桿(gan)式、平衡梁式兩種類型。
