如何提升管殼式換熱器的使用壽命？

管殼式換熱器是工業(yè)生產(chǎn)中重要的熱交換設(shè)備，其使用壽命直接影響生產(chǎn)效率和成本。以下是延長其壽命的關(guān)鍵措施：

一是控制介質(zhì)質(zhì)量。確保進入管殼式換熱器的流體純凈無雜質(zhì)，安裝高精度過濾器去除懸浮顆粒，避免堵塞管道或磨損密封面；對于腐蝕性介質(zhì)，選擇耐蝕材料（如不銹鋼、鈦合金）制作管束與殼體，并添加緩蝕劑降低化學侵蝕風險。

二是優(yōu)化運行參數(shù)。嚴格遵循設(shè)計壓力、溫度范圍操作，避免頻繁啟停造成的熱應(yīng)力沖擊；合理調(diào)節(jié)流速使湍流充分但不過度，減少振動引發(fā)的疲勞損傷。定期監(jiān)測進出口溫差及壓降變化，及時調(diào)整工況異常。

三是加強維護保養(yǎng)。制定周期性清洗計劃，采用化學清洗溶解污垢或機械疏通堵塞通道；檢查法蘭連接處密封墊片老化情況，拆換失效部件以免泄漏；停機時排空內(nèi)部殘留液體并充氮保護，減緩氧化腐蝕進程。

通過科學選材、規(guī)范操作與精細維護相結(jié)合，可以很好的延長管殼式換熱器的使用壽命，保障系統(tǒng)安全穩(wěn)定運行。
