                                        5個氣密性試驗的要求

                                        2012-08-07 0

                                        氣密性試驗主要是檢驗容器的各聯接部位是否有泄漏現象。介質毒性程度為極度、高度危害或設計上不允許有微量泄漏的壓力容器,必須進行氣密性試驗。那么進行氣密性試驗有什么要求呢?今天小編就來帶大家學習一下。

                                        首先,氣密性試驗應在液壓試驗合格后進行。對設計要求作氣壓試驗的壓力容器,氣密性試驗可與氣壓試驗同時進行,試驗壓力應為氣壓試驗的壓力;

                                        其次,碳素鋼和低合金鋼制成的壓力容器,其試驗用氣體的溫度應不低于5℃,其它材料制成的壓力容器按設計圖樣規定;

                                        再次,氣密性試驗所用氣體,應為干燥、清潔的空氣、氮氣或其他惰性氣體;

                                        然后,進行氣密性試驗時,安全附件應安裝齊全;

                                        最后,試驗時壓力應緩慢上升,達到規定試驗壓力后保壓不少于30分鐘,然后降至設計壓力,對所有焊縫和連接部位涂刷肥皂水進行檢查,以無泄漏為合格。如有泄漏,修補后重新進行液壓試驗和氣密性試驗。

                                        上面就是關于氣密性試驗的5個要求的內容,我司專業生產氣密性試驗設備,歡迎詢價!
