Qib IVAR (Ultra - high-}} Valve txhawb nqa cov ntawv thov qib siab)
1. Cov ntsiab lus
Qib IV Rebarsawv cev rau lwm tiam ntawm kev txhawb nqa steel - ibUltra - high - lub zog, ribbed (deformed) qhov cuab lub zog tsim rauHnyav - Desise pob zeb ua qauv, siab vaj tse, tus choj, thiabcov txheej txheem hauv qhov nruab nrab hauv high - seismic lossis siab {1} {luas aones.
Piv rau cov qhab nia qis (I-III), qib IR cov kev them rov qab thiab xa rov qab ntau duaYield lub zog (txog 600 MPA thiab saum toj), tshwj xeebLub zog tensile, thiab txhim khoQaug zog thiab corrosion tsis kamCov. Cov kab no tso cai rau cov engineers rauTxo kev siv hlau noj, Teeb tsim kev hnyav, thiabtxhim kho tsim kev ua haujlwm, thaum tseem tswj kev ua qauv tau txaus thiab kev ua tau zoo nrog pob zeb.
Hauv cov qauv niaj hnub, qib IV yog kwv yees sib npaug rau:
