Phau ntawv qhia no yuav qhia koj txog qhov sib txawv ntawm cov qauv, cov xwm txheej ua haujlwm ib txwm muaj, thiab cov txiaj ntsig thiab qhov tsis zoo ntawm txhua tus qauv. Thaum kawg, koj yuav paub meej tias yuav tsum teev sijhawm twgAPI 600 rooj vag valvethiab thaum ibASME B16.34 lub qhov rooj vag valveyog qhov kev xaiv ntse dua.
API 600 Rooj Vag Valve yog dab tsi?
API 600 yog tus qauv khoom lag luam luam tawm los ntawm American Petroleum Institute. Nws lub npe tag nrho yog *Cov Hlau Rooj Vag Valves - Flanged thiab Butt-welding Ends, Bolted Bonnets*. Thawj zaug luam tawm xyoo 1949, nws tau tsim tshwj xeeb rau kev pabcuam hnyav hauv kev ua roj thiab cov chaw tsim roj av.
Tus qauv no suav nrog cov chav kawm siab txij li Chav Kawm 150 txog Chav Kawm 2500 thiab qhov loj txij li NPS 2 txog NPS 48. Nws txhais ntau dua 20 qhov yuav tsum tau ua, suav nrog cov khoom siv, phab ntsa tuab, txoj kab uas hla ntawm lub qia, kev ua haujlwm sealing, kev tawv tsis kub, thiab kev nyab xeeb hluav taws. Tsab tshiab tshaj plaws (API STD 600: 2021) txhawb nqa qhov xav tau kev tsim qauv puv ntoob, phab ntsa tuab, thiab cov qia loj.
Lub Rooj Vag ASME B16.34 Yog Dab Tsi?
ASME B16.34 yog tus qauv valve yooj yim uas tsim los ntawm American Society of Mechanical Engineers. Nws siv rau flanged, threaded, thiab welding end valves ntawm txhua hom - gate, globe, check, ball, thiab butterfly valves.
Tsis zoo li API 600, uas tsuas yog npog cov qhov rooj vag xwb, ASME B16.34 muab cov ntsuas siab-kub, cov khoom siv (tag nrho 49), cov qauv tuab ntawm phab ntsa, cov cai cim, thiab cov kev cai sim. Nws yog txij li Chav Kawm 150 txog Chav Kawm 4500, thiab ua haujlwm rau qhov kub ntawm -29 ° C txog ntau tshaj 500 ° C, nyob ntawm cov khoom siv.
Cov Qauv Sib Txawv Ntawm API 600 thiab ASME B16.34 Rooj Vag Valves
Ob tug qauv zoo li zoo sib xws thaum xub thawj siab, tab sis lawv cov qauv sab hauv txawv ntau heev.
Phab ntsa tuab
ASME B16.34 qhia meej txogtsawg kawg nkausphab ntsa tuab xav tau rau kev tswj hwm qhov siab kom zoo. Qhov no ua rau cov li qub sib dua thiab tsis kim.
API 600 qhov xav tauphab ntsa ntxiv tuab- feem ntau yog li ntawm 20% ntxiv - uas ua haujlwm ua ib qho kev tso cai xeb uas tau tsim. Cov hlau ntxiv ntawd ua rau lub neej ua haujlwm ntev dua hauv cov chaw ua roj av uas muaj kev xeb.
Tsim qia
API 600 xav tau ib qhotawv, tawv tawvnrog lub cheeb loj dua li cov qauv dav dav. Qhov no tiv thaiv kev khoov thaum muaj kev kub siab lossis thaum lub wedge lo vim yog kev nthuav dav thermal lossis cov khib nyiab.
ASME B16.34 tsis yuam kom lub qia khov kho; cov chaw tsim khoom tuaj yeem xaiv cov qauv tsim uas yoog tau ntau dua yog tias daim ntawv thov tso cai.
Kev Sib Txuas Ntawm Lub Qhov Rooj
Cov li qub API 600 feem ntau siv lub hau ntswj lossis lub hau ntswj uas muaj lub zog siab. Hom lub hau ntswj uas muaj zog siab yuav nruj dua thaum lub zog sab hauv nce siab - zoo tagnrho rau qhov kub thiab txias thiab lub zog siab.
ASME B16.34 tso lub hau qhib, muab kev ywj pheej ntau dua rau cov neeg tsim qauv.
Hom Sealing
API 600 xav tau ib qhokev sib khi hlau-rau-hlaunrog rau kev ua kom tawv (piv txwv li, Stellite) ntawm lub rooj zaum thiab wedge. Qhov no tswj tau qhov kub siab thiab cov khoom me me uas muaj cov khoom me me.
ASME B16.34 tso cai rau cov foob mos lossis cov foob hlau, nyob ntawm tus tsim khoom.
Hom Ntxig thiab Qhov Loj ntawm Qhov
API 600 lub qhov rooj vag valve yuav luag txhua lub sijhawmpuv nkaus(qhov chaw puv nkaus) kom txo qhov tsis kam ntws thiab tiv thaiv cov khib nyiab sib sau ua ke. Cov wedge feem ntau yog cov wedge khov kho lossis yoog tau.
ASME B16.34 tso cai rau cov qauv tsim kom tsawg dua tsuav yog qhov chaw ntws tsawg kawg nkaus ua tau raws li cov kev cai nyab xeeb.
Qhov Hnyav Tag Nrho
Vim yog phab ntsa hnyav dua, lub qia loj dua, thiab lub hau khov dua, ibAPI 600 rooj vag valvehnyav li ntawm 20% ntau dua li ib qhoASME B16.34 lub qhov rooj vag valventawm tib qhov loj thiab chav kawm siab. Qhov hnyav sib txawv ntawd yog qhov tshwm sim ncaj qha ntawm cov qauv tsim sib txawv.
Cov Xwm Txheej Ua Haujlwm - Qhov Twg Txhua Tus Qauv Zoo Tshaj Plaws
Kev Pabcuam Ib Txwm Muaj Rau API 600 Rooj Vag Valves
Koj yuav pom API 600 lub qhov rooj vag hauv cov kev pabcuam kev lag luam nyuaj tshaj plaws:

Yuav Xaiv Li Cas Ntawm API 600 thiab ASME B16.34 Rooj Vag Li Cas
Qhov tseem ceeb yog kom nkag siab txog qhov ntawdAPI 600 tsim raws li ASME B16.34Ib lub qhov rooj vag API 600 kuj yuav tsum ua tau raws li qhov ntsuas kub thiab siab ntawm ASME B16.34. Hauv lwm lo lus, API 600 yog **version uas muaj zog dua** rau kev ua haujlwm hnyav.
Xaiv API 600 thaum:
- Cov xov xwm muaj cov sulfur, hydrogen, cov catalyst fines, lossis cov coke me me.
- Lub zog ntawm cov pa dej siab tshaj 5 MPa (≈725 psi).
- Lub valve nyob rau hauv thaj chaw muaj kev pheej hmoo hluav taws thiab koj xav tau kev nyab xeeb hluav taws.
- Cov kav dej muaj cov voj voog kub lossis kev co ntau zaus - lub qia khov kho thiab phab ntsa hnyav tiv taus kev qaug zog.
Xaiv ASME B16.34 thaum:
- Cov xov xwm yog dej huv, cua, roj inert, lossis roj teeb.
- Chav kawm siab yog Chav Kawm 150 lossis Chav Kawm 300 hauv kev pabcuam tsis xeb.
- Lub kaw lus yog HVAC, dej siv hluav taws xob, lossis dej tua hluav taws.
- Koj xav tau lub qhov rooj tsis yog lub qhov rooj (lub ntiaj teb, daim tshev, pob) - ces ASME B16.34 yog koj tus qauv pib.
Cov xwm txheej tshwj xeeb - kev lag luam fais fab:Cov twj tso kua dej muaj zog siab feem ntau xav tau ob qho tib si API 600 thiab ASME B16.34, ntxiv rau cov qauv ntxiv xws li ASME B16.34 Class 4500 lossis MSS SP‑144 rau kev pabcuam siab thiab kub.
Cov Kev Xav Kawg
API 600thiabASME B16.34tsis yog cov neeg sib tw - lawv ua haujlwm sib txawv. ASME B16.34 muab covpem tebrau kev tsim lub valve kom muaj kev nyab xeeb thoob plaws txhua qhov kev lag luam. API 600 ntxiv ib qholub qab nthab hnyavrau cov roj, roj av, thiab petrochemical sectors.
Yog tias koj teev ib lub qhov rooj vag txheem rau lub tshuab ua roj av lossis cov kav dej loj, mus nrog API 600. Qhov hnyav ntxiv thiab tus nqi them rov qab rau kev ntseeg tau thiab kev nyab xeeb.
Yog tias koj xav tau lub qhov rooj vag dav dav rau cov kav dej txias lossis cov pa dej qis, ASME B16.34 yog qhov txaus thiab pheej yig dua.
Kev nkag siab txog qhov kev sib raug zoo no yuav pab koj kom tsis txhob teev ntau dhau (pov tseg nyiaj) lossis teev tsawg dhau (kev pheej hmoo ua tsis tiav).
