給實(shí)驗室反應釜建議

通過(guò)此次實(shí)驗室反應釜 半管的泄漏修補,我們深刻感受到設備材料和設備制造質(zhì)保文件健康運行的重要性。材料的控制很容易做到,可以通過(guò)嚴格檢查,關(guān)鍵元件選用上等材質(zhì),不合格的材料堅決不予使用等方法。
通過(guò)此次實(shí)驗室反應釜 半管的泄漏修補,我們深刻感受到設備材料和設備制造質(zhì)保文件健康運行的重要性。材料的控制很容易做到,可以通過(guò)嚴格檢查,關(guān)鍵元件選用上等材質(zhì),不合格的材料堅決不予使用等方法。而半管的制造規范目前在國內還是空白,也沒(méi)有詳細的技術(shù)規定。因此希望國家主管部門(mén)能夠盡快制定和完善相關(guān)的標準和技術(shù)規范,以保證化工設備制造的質(zhì)址和水平,提高競爭力。
建議今后在設計和制造螺旋半管夾套實(shí)驗室反應釜半管時(shí),注意以下幾個(gè)方面:
(1)適當增大半管直徑。有利于減少半管之間對接焊縫的個(gè)數和與釜體連接的角焊縫的長(cháng)度,以減少產(chǎn)生焊縫泄漏的兒率。
(2)制造過(guò)程中,要減小裝配應力。半管的直徑公差和橢回度要有限制,減少對接錯邊量,半管的對接焊縫必須全焊透,認真進(jìn)行無(wú)損探傷檢查。
(3)改進(jìn)半管制造工藝。按照圖紙尺寸要求,將半管用板材沖壓成形,這樣既沒(méi)有材料的浪費,而且可以用模具成批制造,節省加工費。
(4)考慮到不同材料的線(xiàn)膨脹系數、導熱系數的差異,半管的材料選用盡量與釜體材料相同,避免因材質(zhì)間的差異增大熱應力而使半管的焊縫受到破壞。
