Ubukhulu obujayelekileko bamavalvu wokuhlola we-ANSI-Standard

Iivalvu yokuhlolaeyakhiwe, yakhiqizwa, yakhiqizwa begodu yahlolwa ngokuya ngezinga le-Amerikha ibizwa ngezinga le-Amerikhaivalvu yokuhlola, njeke ngibuphi ubukhulu obujayelekileko bezinga le-Americaivalvu yokuhlola? Uyini umehluko phakathi kwayo ne-valve yokuhlola ejwayelekileko kazwelonke? Njenganje, ubukhulu obujayelekileko bezinga le-Amerikhaamavalvu wokuhlolaithandwa khulu bona iklanyelwe begodu ikhiqizwe ngokuya ngamazinga we-API ne-ASME, begodu amazinga amanengi we-valve we-America ajayelekile ephasini. Ubukhulu obujayelekileko bamavalvu wokuhlola we-American Standard bulandelako: Amazinga womklamo: API 6D, ASME B16.34, API 594, BS 1868, GB/T 12235, GB/T 12236, JB/T 8937 Ubude besakhiwo: ASME B16.10, APID16.23, amazinga wokuhlanganisa: I-ASME B16.5, i-ASME B16.47, i-ASME B16.25, i-GB/T 9113, i-JB/T 79, i-HG/T 20592 Ukuhlolwa komfutho: API 598, API 6D, GB/T 13927, GB/T 26480 Izinga lokugandeleleka nezinga lokutjhisa: I-ASME B/T ukusetjenziswa kwamavalvu we-Globe ajwayelekileko we-America eendaweni ezinomfutho omkhulu Umehluko omkhulu hlangana nezinga le-Americaamavalvu wokuhlolakanye nezinga lezwe lokeamavalvu wokuhlolazilandelako: 1. Iyunithi yobubanzi obubizwako ihlukile; 2. Itshwayo le-flange lihlukile; 3. Ubude besakhiwo buhlukile; 4. Iimfuneko zokuhlola zihlukile.
