                                        管道壓力試驗機的試驗過程及標準

                                        2012-07-25 0

                                        管道壓力試驗可分為氣壓試驗及液壓試驗,今天小編就各大家簡單了解一下管道壓力試驗機在這兩方面試驗中的應用。

                                        氣壓試驗的過程和標準:

                                        氣壓試驗時,應逐步緩慢增加壓力。當壓力升至試驗壓力的50%時,穩壓30分鐘,如果未發現管道出現異常或泄漏,可繼續按試驗壓力的0%逐級升壓,每級穩壓30分鐘,直至升到試驗壓力,在試驗壓力下穩壓0分鐘,再將壓力降至設計壓力,然后用中性發泡劑對試驗系統仔細巡回檢查,以無泄漏為合格。

                                        液壓試驗的過程及標準:

                                        液壓試驗時,應緩慢升壓,待達到試驗壓力后,穩壓0分鐘,再將試驗壓力降壓至設計壓力,停壓30分鐘,以試驗系統壓力不降低、管道無滲漏為合格。

                                        上面就是關于“管道壓力試驗機的試驗過程及標準”的內容,希望對大家有幫助!另外大家也可以關注“億威仕”微信公眾號,獲取我們的最新資訊!
