Ukukhiqiza, Ukuhlola, kanye Nesitifiketi
Ngemva kokuklama, abakhiqizi bakhiqiza amavalvu. Bafaka ivalvu ngayinye eyenziwe ngokwezifiso ekuhlolweni okuqinile. Lokhu kuqinisekisa ukuthi ihlangabezana nezindinganiso zokusebenza kanye nezindinganiso zokuphepha. Izitifiketi zibalulekile ekusetshenzisweni okubalulekile kwezimboni. Izinhlangano ezifana ne-American Petroleum Institute (API) kanye ne-International Organisation for Standardization (ISO) zinikeza lokhu. I-API ithuthukisa amazinga obuchwepheshe ezimbonini zikawoyela, igesi, kanye nezihlobene. I-ISO ihlanganisa okulindelwe kwekhwalithi emhlabeni jikelele. I-ASME iphinde inikeze amazinga ezicelo zobunjiniyela bemishini ezibanzi. Lezi zitifiketi ziqinisekisa ukuthi amavalvu aphephile, ahlala isikhathi eside, futhi asebenza kahle.
Ukufakwa Nokusekelwa Okuqhubekayo
Ukufakwa okufanele kubalulekile ukuze kusebenze kahle kakhulu ivalvu. Abakhiqizi banikeza iziqondiso zalokhu. Beluleka ukuvikela umzimba womlawuli nokufaka amavalvu okuzihlukanisa. Bancoma nokufakwa okuqondile kwamavalvu okulawula umzimba wonke. Lokhu kuvimbela ukuguguleka kwangaphambi kwesikhathi. Ama-regulator awawona amadivayisi avaliwe; akufanele asetshenziselwe ukulawula ukugeleza kwamanzi. Abakhiqizi banikeza nokusekelwa okuqhubekayo. Lokhu kufaka phakathi ukulungiswa, ukugcinwa, kanye nezixazululo zokuqalisa ezenziwe ngokwezifiso. Banikeza ukuphathwa okuphelele komjikelezo wokuphila, kusukela ekusethweni okusha kwevalvu kuya ekunakekelweni kokuvimbela. Izinsizakalo zifaka phakathi ukwesekwa okuphuthumayo amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto kanye namayunithi okulungisa ahambayo.
Amavalvu okulawula ingcindezi enziwe ngokwezifiso abalulekile emkhakheni we-Oyili neGesi, i-Semiconductor, kanye nowokwakha. Abakhiqizi beValvu Yokulawula Ingcindezi baqinisekisa ukuphepha, ukusebenza kahle, kanye nokuhambisana ngokubhekana ngqo nezinselele zokusebenza ezihlukile. Umklamo okhethekile, ukukhethwa kwezinto, kanye nobunjiniyela obuthuthukisiwe kubalulekile kulezi zimboni ezahlukahlukene. Lezi zixazululo ezilungiselelwe ngokwezifiso zithuthukisa ukuthembeka kohlelo, zandisa impilo yesevisi, futhi zinciphise izindleko zokusebenza, zinikeza izinzuzo ezibalulekile zesikhathi eside. Izitayela zesikhathi esizayo, kufaka phakathi i-virtual prototyping kanye nokukhiqizwa okungeziwe, zizothuthukisa kakhulu lezi zixazululo ezenziwe ngokwezifiso.
