                                        安全閥校驗臺的主要目的及總則

                                        2015-08-24 0

                                        安全閥檢驗臺的目的:

                                        所有安全閥成品應進行出廠試驗。試驗的目的在于確保每臺安全閥都滿足其設計要求,其承壓部件或連接部位不為發生任何形式滲漏,并調整到適合其指定的運行條件。

                                        安全閥檢驗臺的總則:

                                        所有臨時用于試驗的管道、連接件以及封閉裝置應能足夠承受試驗壓力。

                                        試驗后,應仔細地除去所有臨時焊接上的附件,并將留下的焊疤磨到基體齊平,然后用液體滲透或磁粉等無損傷方法進行檢查。

                                        試驗設備上的所有壓力測量裝置應按照相應國家標準規定定期進行校準,以保證精度。
