I-ASTM A193
Ububanzi
Yavunywa ekuqaleni ngo-1936, le ncazelo isetshenziswa kakhulu ekufakweni kwezicelo zokwakhiwa kwe-petroleum namakhemikhali. Izinga le-ASTM lihlanganisa insimbi ye-alloy kanye nezinto zokubhowula zensimbi engagqwali zesevisi yokushisa okuphezulu. Lokhu kucaciswa kufaka phakathi izinsimbi ezihloselwe ukusetshenziswa emikhunjini yokucindezela, ama-valve, ama-flange, nokufakwa. Nakuba, le nto ivamise ukutholakala ku-National coarse (UNC) intambo, uma isetshenziswa ezinhlelweni zendabuko, imicu icaciswa imicu engu-8 iyintshi ngayinye (i-tpi) yamadayamitha angaphezu kweyintshi eyodwa.
Ngezansi isifinyezo esiyisisekelo samabanga ambalwa avamile. I-ASTM A193 ihlanganisa inombolo yezinye izincazelo ezijwayelekile ezingafakwanga kule ncazelo okuhlanganisa i-B5, B6, ne-B16.
