Valve Tsim thiab Engineering
Siab ciam teb thiab lub cev Plhaub
Lub cev thiab lub kaus mom ua lub siab tseem ceeb- khaws cov qauv. Phab ntsa tuab nruj me ntsis ua raws li API 600 thiab ASME B16.34 cov kev cai, muab kev tiv thaiv corrosion txaus thiab cov qauv kev ruaj ntseg tiv thaiv kab mob.
Sealing System thiab Hardfacing
Lub npoo hloov tau them nyiaj rau lub rooj zaum -fim distortion los ntawm thermal expansion lossis piping stress. Lub rooj zaum yog qhov tseeb- tshuab thiab hardfaced nrog Stellite alloys los tiv thaiv galling, yaig, thiab hnav nyob rau hauv kev sib txawv tsis tu ncua.
Stem Seal thiab Packing
Lub nce qia nta ib qho kev sib koom ua ke rov qab uas tso cai rau lub nplhaib hloov kho nyob rau hauv kab siab thaum qhib tag nrho. Tsawg-emission graphite packing nrog anti-corrosion inhibitors tiv thaiv kev khiav tawm ntawm cov pa phem, ua raws li cov qauv kev tswj hwm ib puag ncig.
Kev Ua Haujlwm
Kev tuav tes tuav yog tus qauv rau kev siv qis -torque. Rau loj -dhau los yog siab- cov kab sib txawv, bevel iav tswv lossis actuators (pneumatic lossis hluav taws xob) yog qhov loj me raws li qhov siab tshaj plaws kev khiav hauj lwm sib txawv torque es tsis yog valve txoj kab uas hla ib leeg.

FAQ
Q: Dab tsi yog lub luag haujlwm tseem ceeb ntawm kev kub siab cais lub rooj vag valve?
A: Nws yog siv los ua kom tiav kev kaw ntawm cov kav dej, cov khoom siv, lossis cov kav dej. Nws cov qauv tsim sab hauv yog ua kom zoo rau tag nrho - qhib lossis tag nrho - kaw kev sib cais es tsis yog ntws throttling lossis kev cai.
Q: Vim li cas API 600 rooj vag li qub nyiam siv rau kev siv petrochemical?
A: API 600 qhia txog qhov hnyav dua lub cev phab ntsa thickness piv rau cov qauv li qub. Cov phab ntsa ntxiv no muab cov cuab yeej zoo tshaj plaws, kev tiv thaiv corrosion zoo dua, thiab txhim kho kev nyab xeeb nyob rau hauv siab thiab thermal shock.
Q: Qhov txawv ntawm API 600 thiab API 603 lub rooj vag valve yog dab tsi?
A: API 600 li qub muaj qhov muaj zog, hnyav- phab ntsa tsim tsim nyog rau kev siv siab ua haujlwm siab -. API 603 li qub yog lub teeb-walled stainless hlau li qub tsim los rau qis dua -siab corrosion kuj qhov twg qhov hnyav optimization yuav tsum tau.
Q: Thaum twg yuav tsum tau teev cov rooj zaum hlau nrog Stellite hardfacing?
A: Stellite hardfacing yog pom zoo rau kev khiav hauj lwm kub siab tshaj 260 degree, siab sib txawv siab, los yog abrasive xov xwm los tiv thaiv lub rooj zaum galling, nto yaig, thiab ua tsis taus pa sealing ntxov.
Q: Cov valve no puas tuaj yeem muab rau cov kev pabcuam roj qaub raws li NACE cov qauv?
A: Yog. Cov pa roj carbon steel thiab alloy rooj vag li qub tuaj yeem tsim tau nrog kev tswj hwm qib hardness, ua raws bolting, thiab tshwj xeeb corrosion-cov khoom siv tiv thaiv nyob rau hauv tag nrho raws li NACE MR0175 / ISO 15156.
