API 598 thiab API 609 yog ob tus yuam sij tab sis cov qauv sib txawv ntawm cov roj av hauv kev lag luam roj av. Lub ntsiab sib txawv yog raws li hauv qab no:
1. Txheem Xwm thiab
API 598 yog qhov ntsuas ntsuas qhov hluav taws xob dav dav, uas muaj feem xyuam rau kev tshuaj xyuas thiab ntsuas qhov siab ntawm ntau yam li qub, kos li qub, Npauj Npaim Li Qub, thiab lwm yam.
Cov ntsiab lus tseem ceeb: Nws qhia txog cov hau kev thiab kev lees paub rau valve lub zog kuaj, kev xeem ntawv siab (tsis tshua muaj siab), sab saud sealing kuaj, thiab lwm yam.
API 609 yog tus npauj npaim valve tshwj xeeb tsim qauv thiab cov qauv tsim qauv, cov ntaub ntawv thiab kev ua tau zoo ntawm ob flange, wafefer thiab log thiab cov npauj npaim li qub.
Cov ntsiab lus tseem ceeb: Nws npog cov ntsiab lus tseem ceeb xws li cov qauv npauj npaim li qub (xws li ob npaug eccentricity), torque yam tsim nyog, thiab kev ua haujlwm tsim qauv.
2. Cov ntsiab lus sib txawv
API 598 Muaj nuj nqi
Txheeb xyuas lub pob hluav taws xob khi kev ua tau zoo (xws li lub rooj kev lim dej) thiab cov qauv txheej txheem kev ntseeg (xws li plhaub siab coj tus nqi).
Leakage levels are classified according to API 598 (such as Class IV/V/VI), which is the mandatory inspection basis for valves to leave the factory or be accepted.
API 609 lub luag haujlwm
Qhia meej cov qauv tsim (xws li ntws channel loj, ncej xaiv (qhib lub zog (qhib thiab kaw cov khoom siv ntawm npauj npaim li qub.
Qhia txog kev ntseeg tau ntawm Npauj npaim li qub mob (xws li cov ntsaws ruaj ruaj uas yuav tsum ua tiav cov qib v lossis qib v lossis siab dua).
3. Daim Ntawv Thov Kev Sau Npe
API 598:
Muaj feem xyuam rau qhov kawg ua tau zoo kawg nkaus ntawm txhua tus qauv API (xws li API 600 lub rooj vag li qub, api 608 pob li qub).
Qhov kev soj ntsuam thib peb thaum cov neeg siv khoom yuav li qub kom paub meej tias cov khoom raws li cov kev ua haujlwm sib dhos.
API 609:
Phau Ntawv Qhia Cov Chaw Tsim Tshuaj Los tsim cov khoom lag luam npauj npaim li qub
Tsim qauv rau Npauj npaim Valve xaiv nyob rau hauv cov khoos kas tshwj xeeb (xws li kev nyab xeeb nrog kev nyab xeeb kaw).
4. Cov qauv ntsuas
Tom qab kev tsim khoom, API 609 npauj npaim li cas yuav tsum dhau api 598 xeem thiab ntawv pov thawj ua ntej lawv tuaj yeem muab tso rau hauv kev siv.
Piv txwv li: Kev sib khi ua tau zoo ntawm API 609 npauj npaim yuav tsum yog tus qauv raws li v lossis chav VI of API 598.
