FLANGE INTRODUCTION

Lub cev Specifications
Ua ntej thiab qhov tseem ceeb, lub flange yuav tsum haum rau cov yeeb nkab lossis cov khoom siv uas nws tsim.Lub cev tshwj xeeb rau cov yeeb nkab flanges suav nrog qhov ntev thiab cov duab tsim.

Flange Dimensions
Lub cev qhov ntev yuav tsum tau teev nyob rau hauv thiaj li yuav loj flanges kom raug.

Sab nraud txoj kab uas hla (OD) yog qhov kev ncua deb ntawm ob qhov sib txawv ntawm qhov flange lub ntsej muag.
Thickness yog hais txog qhov tuab ntawm cov hlua txuas sab nraud, thiab tsis suav nrog qhov flange uas tuav cov yeeb nkab.
Bolt lub voj voog txoj kab uas hla yog qhov ntev ntawm qhov nruab nrab ntawm lub qhov ntsia liaj qhov rooj mus rau qhov chaw ntawm lub qhov tawm tsam.
Cov yeeb nkab loj yog cov yeeb nkab flange cov yeeb nkab sib txuas, feem ntau ua raws li cov qauv lees paub.Nws yog feem ntau teev los ntawm ob tus lej tsis-dimensional, nominal pipe size (NPS) thiab lub sijhawm (SCH).
Nominal bore loj yog lub puab kab uas hla ntawm lub flange connector.Thaum tsim khoom thiab xaj txhua yam ntawm cov yeeb nkab txuas, nws yog ib qho tseem ceeb kom phim lub bore loj ntawm daim nrog lub bore loj ntawm mating yeeb nkab.
Flange Lub ntsej muag
Flange ntsej muag tuaj yeem tsim tau rau ntau tus qauv kev cai raws li kev tsim qauv.Qee qhov piv txwv suav nrog:

Pav ca
Raised ntsej muag (RF)
Lub nplhaib hom sib koom (RTJ)
O-ring zawj
Hom yeeb nkab Flanges
Cov yeeb nkab flanges tuaj yeem muab faib ua yim hom raws li kev tsim.Cov hom no yog qhov muag tsis pom kev, lub puab tsaig sib koom tes, orifice, txo qis, plam-rau, qhov (socket-weld), threaded, thiab weld caj dab.

Qhov muag tsis pom flanges yog daim hlau puag ncig uas tsis muaj qhov chaw tuav siv los kaw qhov kawg ntawm cov kav dej, li qub, lossis cov khoom siv.Lawv pab kom yooj yim nkag mus rau ib txoj kab thaum nws tau raug kaw lawm.Lawv kuj tuaj yeem siv rau kev ntsuas siab ntws.Qhov muag tsis pom flanges yog tsim kom haum cov kav dej hauv txhua qhov ntau thiab tsawg ntawm kev ntsuas siab dua li lwm hom flange.

Lap Joint flanges yog siv rau ntawm cov kav dej haum nrog lapped yeeb nkab los yog nrog lub puab tsaig sib koom ua ke.Lawv tuaj yeem tig ib ncig ntawm cov yeeb nkab kom tso cai rau kev sib dhos yooj yim thiab sib dhos ntawm cov ntsia hlau qhov txawm tias tom qab cov welds tiav lawm.Vim qhov txiaj ntsig no, lap joint flanges yog siv rau hauv cov tshuab uas yuav tsum tau nquag disassembly ntawm flanges thiab yeeb nkab.Lawv zoo ib yam li plam-on flanges, tab sis muaj lub vojvoog nkhaus ntawm lub bore thiab lub ntsej muag kom haum rau lub puab tsaig sib koom ua ke kawg.Cov kev ntsuas siab rau lub puab tsaig flanges yog qhov tsawg, tab sis siab dua rau plam-on flanges.

Slip-on flanges yog tsim los xaub hla qhov kawg ntawm cov kav dej thiab tom qab ntawd muab welded rau hauv qhov chaw.Lawv muab kev yooj yim thiab tus nqi qis thiab yog qhov zoo tagnrho rau kev siv qis dua.

Qhov (socket) weld flanges yog qhov zoo tagnrho rau cov kav dej me me, muaj zog siab.Lawv fabrication yog zoo ib yam li cov plam-on flanges, tab sis lub hnab tshos sab hauv tsim tso cai rau ib tug du bore thiab cov kua dej zoo dua.Thaum welded sab hauv, cov flanges no kuj muaj zog qaug zog 50% ntau dua ob npaug welded slip-on flanges.

Threaded flanges yog hom tshwj xeeb ntawm cov yeeb nkab flange uas tuaj yeem txuas rau cov yeeb nkab yam tsis muaj vuam.Lawv yog threaded nyob rau hauv lub bore kom phim lwm threading ntawm ib tug yeeb nkab thiab yog tapered los tsim ib lub foob ntawm lub flange thiab cov yeeb nkab.Foob welds kuj tseem siv tau nrog rau kev sib txuas nrog rau kev ntxiv dag zog thiab sealing.Lawv yog qhov zoo tshaj plaws siv rau cov kav dej me me thiab tsis tshua muaj siab, thiab yuav tsum tau zam hauv kev siv nrog cov khoom loj thiab lub zog siab.

Vuam caj dab flanges muaj qhov ntev tapered hub thiab siv rau kev siv siab.Lub hub tapered hloov kev ntxhov siab los ntawm flange mus rau cov yeeb nkab nws tus kheej thiab muab lub zog txhawb zog uas tiv thaiv kev tawg.
