Flange

Ib lub flange yog lub disk lossis phaj uas txuas nrog ib qho khoom, xws li cov yeeb nkab, valve, lossis tso kua mis, los muab cov khoom tiaj uas tuaj yeem siv los txuas cov khoom rau lwm feem. Flanges feem ntau yog siv nyob rau hauv cov yeeb nkab seem rau cov yeeb nkab ua ke lossis txuas cov kav dej mus rau lwm cov khoom siv. Lawv tuaj yeem raug nyab xeeb nrog bolts, screws, lossis feem ntau yog tsim los ntawm cov ntaub ntawv xws li hlau, lossis yas kom phim cov khoom siv ntawm cov yeeb nkab lossis khoom siv uas lawv sib txuas. Flanges tuaj nyob rau ntau qhov ntau thiab tsawg thiab cov kev ntsuas siab, tso cai rau lawv siv ntau ntawm cov kev siv los ntawm cov txheej txheem siab muaj siab.

Qhov tseem ceeb tshaj plaws,Qhov ntev ntawm flanges suav nrog cov hauv qab no tseem ceeb:

• Nominal yeeb nkab loj (nps): Qhov no yog qhov qauv tsim qauv rau cov flanges, uas yog cuam tshuam nrog cov kabinal hla (DN) hauv cov qauv thoob ntiaj teb. Piv txwv li, NPS 1/2 raug rau DN 15, thiab NPS 1 raug rau DN 25.
• Flange txoj kab: Cov inter sab nraud (OD) thiab sab hauv lub taub (ID) ntawm Flange sib txawv raws li chav kawm Nps thiab siab.
• Bolt Vvende Diam: Qhov no yog txoj kab uas hla ntawm lub voj voog tsim los ntawm cov chaw zov me nyuam ntawm cov qhov ntsia liaj qhov rooj. Tus lej thiab lub cheeb ntawm lub bolts tseem nyob ntawm cov flange loj thiab siab ntaus nqi.
• Flange tuab: Cov tuab tuab ntawm cov flange nce nrog qhov loj thiab cov chav kawm siab kom ntseeg tau txoj kev ncaj ncees.

Cov Chav Kawm Siab:

Flanges muaj nyob hauv cov chav kawm siab sib txawv, xws li 150 #, 300 #, 600 #, 900 #, thiab 2500 #. Cov tub kawm ntawv siab dua, muaj ntau dua lub siab cov flange tuaj yeem tiv thaiv tau.

Flange Qhov ntev yog ib txwm qauv los ntawm cov koom haum xws liASME(American Society of cov neeg kho tshuab engineers),Mss(Cov Cuab Yeej Tsim Kho Cov Txheej Txheem), thiabAPI(American Petroleum lub koom haum). Tus qauv siv dav tshaj plaws yogASME B16.5, uas npog cov yeeb nkab flanges thiab flanged fittings los ntawm NPS 1/2 rau Nps 24 hauv ntau chav kawm siab.En 1092-1, DIN 2501, 

ISO 7005, Jis B2220, yog siv dav.

Kev xaiv ntawm qib STEED rau ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov, xws li siab, kub, thiab corrosion tsis kam. Ntawm no yog qee cov qauv siv hlau siv hauv Flanges:
Carbon Steel:

• ASTM A105: Qhov no yog cov qib steel hlau rau qib vim nws lub zog zoo thiab muaj zog. Nws yog qhov haum rau cov ntawv thov kev lag luam dav dav.
• BS en {1092-1}: Cov qauv no npog cov hlau hlau flanges nrog ntau qhov kev ntsuas siab (PN 6 mus rau DN 100000).

Alloy Steel:

• ASTM A182 F11 thiab F22: Cov no yog cov qib steel tsawg paub txog lawv lub zog txhim kho thiab muaj peev xwm tiv thaiv tau ntau dua thiab kub.
• DIN 17175: Tus qauv German tus qauv no siv rau cov kev siv steel hlau siv cov kev siv hluav taws xob siab thiab ntsuas kub.

Tus Hlau Stainless:

• ASTM A182 F304 thiab F316: Cov qhab nia no tau nrov rau lawv cov khoom lag luam corrosion tsis kam, ua rau lawv ua lag luam ua khoom noj.
• JIS G4303: Tus qauv Japanese no suav nrog cov hlau stainless flanges nrog cov qib nyiam sus 304 thiab siv nyob rau hauv cov chaw siab corrosion.

Weld Neck Flange: Paub txog lub zog siab, siv rau cov tshuab siab siab. Nws muaj caj dab ntev uas yog welded rau yeeb nkab.

NplUAV-RAU FOOGLE: Yooj yim rau nruab raws li nws swb rau cov yeeb nkab thiab yog welded nyob rau hauv qhov chaw. Haum rau cov ntawv thov tsawg-.

Qhov muag tsis pom Flange: Siv los kaw qhov xaus ntawm cov twj piping lossis siab siab siab.

Xov flange: Tsim los ntsia hlau mus rau cov yeeb nkab tsis muaj vuam, haum rau cov tshuab qes.

Qhov (socket) weld flange: Tso cai rau cov yeeb nkab tau muab tso rau hauv lub qhov (socket) thiab welded nyob rau hauv qhov chaw, siv rau cov xov tooj cua siab.

Muab cov hlua khi ua ke: Muaj ib tug stub kawg thiab flange flange, tso cai rau kev sib dhos yooj yim thiab sib dhos.

Forging yog ib txheej txheem tsim khoom uas hlau yog puab los ntawm kev thov cont compressive. Muaj ob hom kev sau fillinging siv rau flanges:

Qhib Tuag Felding: Cov qauv no tsawg hauv kev ua haujlwm tau zoo thiab yuav tsum muaj ntau yam hnyav, tab sis nws yog verloload, tab sis nws yog ntau yam thiab haum rau cov khoom siv yooj yim thiab me-ntau ntau lawm.

Kaw Tuag Forging (kev ua kom haum rau Forging): Cov txheej txheem no yog siab nyob rau hauv kev ua tau zoo, yooj yim rau kev khiav lag luam, thiab tuaj yeem ua mechanized lossis automated. Nws ua tau nyob rau hauv siab qhov tseeb yog thiab ib tug ntxiv cov khoom lag luam lis cov hlau tsim nyog, uas tuaj yeem txhim kho kev pabcuam lub neej ntawm Flange ntu.

Plaub txoj kev tsim khoom tseem ceeb rau cov flanges yog forging, casting, txiav, thiab dov:

Chaw ua casuming: Cuam tshuam poping molting hlau mus rau hauv cov kab tsuag casing uas conforms rau cov duab ntawm flange. Txoj kev no tuaj yeem ua rau muaj kev tsis xws luag thiab cov kab nrib pleb.

Kev zam: Feem ntau tshwm sim nyob rau hauv qis dua cov ntsiab lus roj teeb thiab muaj xeb zoo dua xeb, nrog rau cov qauv sib xyaw ntau dua thiab muaj peev xwm ntau dua piv rau cov flanges.

Txiav: Cuam tshuam nrog kev txiav cov sab hauv thiab txheej txheej ntawm cov taub thiab cov thickness ncaj qha tawm ntawm cov hlau phaj, tom qab ntawd ua tus ntsia liaj qhov rooj lub qhov thiab dej.

Dov: Ua los ntawm txiav cov nruab nrab phaj rau hauv ib daim hlab, ces dov nws rau hauv cov khoom siv welded thiab plev nws.

Flanges tau siv thoob plaws kev lag luam, txhua tus nrog cov kev xav tau tshwj xeeb:

Roj thiab Roj Kev Lag Luam: Flanges yog qhov tseem ceeb rau kev txuas kav dej, li qub, thiab lwm yam khoom siv, kom muaj kev nyab xeeb thauj cov kua thiab roj av.

Tshuaj Nroj Tsuag: Kev siv hluav taws xob siab thiab ntsuas kub siab xws li Weld Neck Flanges muaj ntau.

Dej Kho Nroj Tsuag: Cov ntawv thov qis-siab zoo li khau khiab-ntawm flanges yog siv vim lawv qhov yooj yim ntawm kev teeb tsa thiab tus nqi-ua hauj lwm zoo.

Cov tshuab hydraulic: Qhov (cov pob tw weld

Kav dej: Threaded flanges yog qhov zoo tshaj rau cov qes, cov tshuab ntsuas qis uas vuam tsis muaj peev xwm ua tau.

Txhua hom flange thiab tsim cov txheej txheem tsim muaj cov tshwj xeeb thiab cov txiaj ntsig, catering rau cov ntawv thov sib txawv. Nkag siab txog cov kev sib txawv no yog qhov tseem ceeb rau cov kws tsim khoom siv rau cov yeeb nkab rau cov yeeb nkab thiab ua kom muaj kev sib raug zoo nrog kev ua haujlwm.
