Dab tsi yog hom flanges?
Dab tsi yog flange
Flanges yog qhov chaw uas txuas cov kav dej rau ib leeg thiab siv rau kev sib txuas ntawm cov yeeb nkab kawg; lawv kuj tseem siv los ua flanges ntawm qhov nkag thiab qhov hluav taws xob ntawm cov khoom siv rau kev sib txuas ntawm ob lub cuab yeej, xws li reducer flanges. Flange kev twb kev txuas lossis flange sib koom yog hais txog kev sib txuas uas tsis tuaj yeem sib txuas uas flanges, gaskets thiab bolts txuas rau ib leeg raws li cov txheej txheem sib khi ua ke.
Kev faib tawm ntawm flanges
Feem ntau siv flange hom hauv cov raj xa dej yog caj dab taub qab vuam flanges, lub taub qab ntev vuam flanges, zawv zawg lub tes tsho flanges, lub qhov (socket vuam flanges), ncej puab flanges, threaded flanges thiab dig muag flanges. Ntxiv rau cov qauv flanges no, kuj tseem muaj cov flanges tshwj xeeb hu ua Weldoflange / Nipoflange thiab Elboflange, swivel flanges, loj / txo flanges thiab orifice flanges. cov
Standard hom flange
Hom flange siv rau kev siv cov kav dej yog nyob ntawm qhov xav tau lub zog ntawm flange sib koom ua ke. Siv flanges es tsis txhob siv cov kev sib txuas welded los pab tswj kev ua haujlwm (flange pob qij txha tuaj yeem raug tshem tawm sai thiab yooj yim).
Kab lus no yuav qhia ntau yam siv flanges rau siv
Butt welding flange nrog caj dab
Ib lub taub qabweld flange ("WN")muaj ib tug ntev tapered hub uas yog welded rau cov yeeb nkab. Hom flange no feem ntau yog siv rau hauv high-pressure thiab high / low-temperature applications qhov twg cov kua thauj los ntawm cov kav dej yuav tsum tsis txhob txwv (qhov bore ntawm flange phim lub bore ntawm cov yeeb nkab). Qhov tsis muaj lub siab poob qis tapered hub tso cai rau kev sib faib ntawm cov neeg kho tshuab kev ntxhov siab ntawm cov yeeb nkab thiab lub taub qab vuam flange thiab ua kom yooj yim rau kev tshuaj xyuas hluav taws xob txhawm rau txhawm rau txhawm rau txhawm rau thiab vuam tsis xws luag. Cov teebmeem tsis zoo xws li turbulence thiab yaig / corrosion ntawm cov hlau ze flange pob qij txha tuaj yeem tiv thaiv. Flange loj (NPS thiab cov yeeb nkab loj) yuav tsum phim qhov loj ntawm cov yeeb nkab txuas. Butt weld flanges txuas nrog cov yeeb nkab nrog ib qho kev nkag mus rau V-shaped taub qab vuam.
zawv zawg flange
Ib tug plam-on flange yog txuas nrog cov yeeb nkab los yog haum los ntawm ob lub fillet welds, ib sab hauv thiab ib qho sab nraum lub flange kab noj hniav. Lub bore kab ntawm lub tes tsho flange yog loj dua lub sab nraud txoj kab uas hla ntawm cov yeeb nkab txuas vim hais tias cov yeeb nkab yuav tsum swb nyob rau hauv lub flange yuav tsum tau kev cob cog rua los ntawm kev ua ib tug fillet weld. Slip-on flanges kuj txhais tau tias "hub flanges" thiab yooj yim txheeb xyuas vim lawv cov duab slim, compact.
Qhov sib txawv ntawm pob tw vuam flange thiab zawv zawg flange
Los ntawm kev pom kev siv, flange pob qij txha ua nrog zawv zawg lub tes tsho flanges yog qhov tsis yooj yim dua li kev sib txuas nrog pob tw vuam flanges (nyob rau hauv cov xwm txheej zoo sib xws). Qhov no zoo nkaus li yog vim lub fact tias pob tw weld flanges muaj ib tug tapered hub uas lub qhov (socket) weld flanges tsis muaj, uas ntau tusyees faib cov neeg kho tshuab kev nyuaj siab ntawm cov yeeb nkab thiab flange. Weld caj dab pob qij txha tsuas muaj ib qho chaw vuam xwb tsis yog ob (socket weld flange). Lwm qhov zoo dua ntawm lub pob tw weld flange yog tias nws tuaj yeem txuas nrog cov kav dej thiab fittings, thaum lub qhov (socket weld flange) tsuas yog tsim rau cov kav dej.
Qhov muag tsis pom flange
Contrary rau tag nrho cov flange hom peb tau pom saum toj no, qhov muag tsis pom flanges tsis muaj lub hauv paus qhov thiab yog siv los thaiv los yog kaw cov kav dej, li qub / cov hlab ntsha siab thiab tiv thaiv cov dej ntws.Qhov muag tsis pom flangesyuav tsum tiv taus cov neeg kho tshuab kev ntxhov siab vim qhov system pressures thiab yuav tsum tau bolt rog. Qhov muag tsis pom flanges tso cai yooj yim nkag mus rau cov kav dej vim lawv tso cai yooj yim loosening ntawm bolts kom tso cai rau cov neeg ua haujlwm ua haujlwm nyob rau hauv cov yeeb nkab txiav (qhov no kuj yog vim li cas vim li cas qhov muag tsis pom flange qee zaum siv los ua cov hlab ntsha siab). Qhov kev txhawj xeeb tshaj plaws yog tias txawm hais tias hom flange no yooj yim dua rau kev tsim khoom, lawv muaj tus nqi nruab nrab ntau dua ib kilogram piv rau lwm hom flange.
Xaws flange
Loose sleeve flange yog ib txoj kev siv flange txuas, tseem hu ua "sleeve sleeve coupling". Nws muaj ob lub flanges thiab lub tes tsho, qhov twg txhua lub flange txuas nrog lub flange ntawm cov yeeb nkab lossis cov khoom siv sib txuas, thiab lub tes tsho ruaj ntseg ob lub flanges ua ke los ntawm bolts. Nws yog feem ntau siv nyob rau hauv cov xwm txheej uas qhov nruab nrab kub thiab siab tsis siab tab sis qhov nruab nrab yog heev corrosive. Thaum lub nruab nrab yog corrosive heev, ib feem ntawm lub flange uas hu rau nruab nrab (lub flanged txiv mis) yog ua los ntawm corrosion-resistant high-grade cov ntaub ntawv, xws li stainless hlau, thaum sab nraud yog clamped los ntawm ib tug flange nplhaib ua los ntawm tsawg- cov ntaub ntawv qib xws li carbon steel. Nws ua tiav sealing.
Lub ntsiab nta ntawm xoob flanges yog simplicity, kev ntseeg tau thiab yooj yim ntawm disassembly. Nws yog qhov tsim nyog rau kev sib txuas ntawm ntau lub raj xa dej thiab cov cuab yeej siv, xws li cov kav dej, twj tso kua mis, lub valve, ntim, thiab lwm yam uas thauj cov kua, gases los yog hais.
Thaum lub sij hawm kev sib txuas ntawm lub tes tsho xoob flanges, lub tes tsho yog thawj zaug muab tso rau ntawm ob lub flanges yuav tsum tau txuas nrog, thiab tom qab ntawd lawv tau tsau ua ke los ntawm bolts. Bolts feem ntau yog nyob rau ntawm qhov chaw ntawm lub flange thiab nruj nrog cov txiv ntseej kom ntseeg tau tias kev ruaj ntseg thiab kev sib khi ntawm kev sib txuas. Tsis tas li ntawd, gaskets lossis gaskets tuaj yeem muab ntxiv ntawm flanges kom muab lub foob zoo dua.
Qhov zoo ntawm xoob flange
Ib qho yooj yim installation thiab disassembly: Vim lub xoob flange txuas nrog bolts, nws tuaj yeem ntsia tau sai thiab disassembled, ua kom yooj yim los tswj thiab hloov khoom siv.
Flexibility thiab yoog raws: Lub tes tsho xoob flanges tuaj yeem txuas cov kav dej lossis cov khoom siv ntawm cov kab sib txawv thiab cov ntaub ntawv, thiab muaj ntau yam kev siv.
Kev ruaj ntseg sealing kev ua tau zoo: Los ntawm kev xaiv thiab txhim kho sealing gaskets los yog ntxhua khaub ncaws, kev sib khi zoo tuaj yeem ua tiav thiab tuaj yeem tiv thaiv tau.
Tus nqi qis: Piv nrog rau lwm hom flange kev sib txuas txoj kev, xoob flanges muaj cov nqi tsim khoom qis dua thiab tsim nyog rau qee qhov kev siv nrog kev xav tau nyiaj txiag ntau dua.
Nws yuav tsum tau muab sau tseg tias xoob raj flanges tej zaum yuav muaj tej yam kev txwv nyob rau hauv ib co kub kub, siab kub los yog hnyav ua hauj lwm tej yam kev mob. Yog li ntawd, thaum xaiv ib tug haum flange kev twb kev txuas txoj kev, koj yuav tsum xav txog tej yam engineering yuav tsum tau thiab daim ntawv thov ib puag ncig.
Hauv kev xaus
Los ntawm kev qhia txog cov flanges saum toj no hauv av, peb nkag siab tias cov flanges sib txawv muaj cov haujlwm sib txawv thiab lawv daim ntawv thov scenarios kuj txawv heev. Yog li ntawd, thaum xaiv ib tug flange, peb yuav tsum consider peb daim ntawv thov ib puag ncig, lub hom phiaj, thiab Qhov nruab nrab thiab siab qhov ntsuas tau raug xaiv nyob rau hauv ntau qhov xwm txheej.
