                                        高壓閥門檢驗需知

                                        2012-10-12 0

                                        高壓閥門制造過程中的檢驗與普通閥門基本相同,如檢驗程序、檢驗依據、檢驗內容、檢驗方法等。但由于高壓閥門的工作條件比普通閥門苛刻,因此會有更多的要求,如無損探傷等。那么高壓閥門的檢驗我們需要知道什么呢?

                                        首先,需知道高壓閥門檢驗依據,高壓閥門檢驗依據下列文件:

                                        (1)以產品圖紙為主的設計文件;

                                        (2)工藝文件;

                                        (3)相關標準(包括產品設計、制造標準、材料標準、產品檢驗和試驗標準等);

                                        (4)與用戶簽訂的合同和技術協議等。

                                        其次,需知道高壓閥門檢驗內容,主要包括:

                                        (1)材料檢驗

                                        (2)無損探傷

                                        (3)尺寸檢驗

                                        (4)裝配檢驗

                                        (5)試壓(殼體強度和密封)

                                        (6)最終檢驗等。
