Flangetseem hu ua flange convex disk lossis convex phaj.Raws li rau cov neeg koom nrog kev siv tshuab lossis engineering installation ntawm cov koom tes me me, lawv yuav tsum paub zoo heevflange.Nws yog ib qho disk-puab qhov chaw, feem ntau yog siv los ua khub.Nws yog siv los ntawm cov yeeb nkab thiab lub valve, nruab nrab ntawm cov yeeb nkab thiab cov yeeb nkab thiab nruab nrab ntawm cov yeeb nkab thiab cov khoom siv, thiab lwm yam. Nws yog cov khoom sib txuas nrog cov nyhuv sealing.Muaj ntau daim ntawv thov ntawm cov khoom siv thiab cov kav dej, yog li ob lub dav hlau txuas nrog bolts, thiab cov khoom sib txuas nrog cov nyhuv sealing yog hu uaflange.
Feem ntau, muaj qhov puag ncig ntawm lubflangemus ua lub luag haujlwm ruaj.Piv txwv li, thaum siv ntawm cov yeeb nkab sib txuas, lub nplhaib sib khi yog ntxiv ntawm obflange phaj.Thiab tom qab ntawd qhov kev sib txuas yog nruj nrog bolts.Lub flange nrog lub siab sib txawv muaj qhov sib txawv thickness thiab txawv bolts.Cov ntaub ntawv tseem ceeb siv rau flange yog carbon steel, stainless hlau thiab hlau alloy, thiab lwm yam.
Vim nws lub luag haujlwm tseem ceeb thiab kev ua haujlwm zoo,flangeyog dav siv nyob rau hauv chemical, petrochemical, hluav taws kub thiab dej industries.
Raws li ib yam ntawm connector,flangeyog dav siv nyob rau hauv lub ntiaj teb no, uas yuav tsum tau ib tug unified standard.Piv txwv li, muaj ob tug txheej txheem raucev flange.
Lawv yog European pipeline flange system, uas yog European pipeline flange system sawv cev los ntawm German DIN (xws li Russia), thiab American pipeline flange system sawv cev los ntawm American ANSI yeeb nkab flange.
Tsis tas li ntawd, muaj JIS pipeline flange system nyob rau hauv Nyiv thiab steel yeeb nkab flange system GB nyob rau hauv Tuam Tshoj, tab sis lub ntsiab qhov ntev yog raws li nyob rau hauv European system thiab American system.
Hom flange
Cov qauv ntawm covflangeyog qhov yooj yim.Nws yog tsim los ntawm sab sauv thiab qis flange daim hlau, nruab nrab gasket thiab ob peb bolts thiab ceev.
Los ntawm kev txhais ntawmflange, peb tuaj yeem paub tias muaj ntau yamflange, thiab nws qhov kev faib tawm yuav tsum txawv ntawm qhov sib txawv.Piv txwv li, raws li kev sib txuas hom, flange tuaj yeem muab faib uaib flange,tiaj welding flange,taub qab vuam flange,lub tes tsho xoob flangethiab thlau flange, uas kuj yog flange.
Integral flange (IF)feem ntau yog siv rau hauv cov raj xa dej nrog kev kub siab.Nws yog ib hom flange kev twb kev txuas hom, thiab muaj lub caj dab ntev.Nws feem ntau yog tsim los ntawm ib lub sij hawm ib qho casting, thiab cov ntaub ntawv siv feem ntau yog carbon steel, stainless hlau, thiab lwm yam.
Flat vuam flangetseem hu ua ntauwd vuam flange.Nws yog ua tiav los ntawm kev vuam thaum txuas nrog lub nkoj lossis cov kav dej.Qhov zoo ntawm cov vuam flange no muaj cov yam ntxwv ntawm kev sib dhos yooj yim thiab tus nqi qis.Nws yog tsuas yog siv nyob rau hauv cov kav dej nrog tsawg dua siab thiab kev co.
Lub taub qab vuam flangetseem hu ua siab caj dab flange.Qhov sib txawv loj tshaj plaws ntawm lub pob tw vuam flange thiab lwm yam flanges yog tias nws muaj lub caj dab siab protruding.Cov phab ntsa tuab ntawm lub caj dab siab protruding yuav maj mam zoo ib yam li lub thickness thiab txoj kab uas hla ntawm cov yeeb nkab phab ntsa yuav tsum tau butted nrog qhov siab, uas yuav ua rau kom lub zog ntawm flange.Butt welded flange feem ntau yog siv rau hauv qhov chaw uas muaj kev hloov pauv loj hauv ib puag ncig, xws li qhov kub thiab txias, kev kub siab thiab qis qis.
Xaws flangetseem hu ua looper flange.Hom flange no feem ntau yog siv rau qee cov hlau tsis-ferrous thiab stainless hlau kav, thiab kev sib txuas yog pom tau los ntawm vuam.Nws tuaj yeem tig tau.Thiab nws yog ib qho yooj yim los kho qhov ntsia hlau qhov, yog li nws feem ntau yog siv rau hauv kev sib txuas ntawm txoj kab uas hla loj thiab feem ntau yuav tsum tau disassembled.Txawm li cas los xij, lub siab tsis kam ntawm xoob flange tsis siab.Yog li nws tsuas yog siv tau rau kev sib txuas ntawm cov kav dej uas tsis tshua muaj siab.
Muaj threads nyob rau hauvflange phajntawmthreaded flange, uas yuav tsum tau hais tias cov yeeb nkab sab hauv kuj muaj cov xov sab nraud kom paub txog kev sib txuas.Nws yog ib qho uas tsis yog vuam flange, yog li nws muaj qhov zoo ntawm kev yooj yim installation thiab disassembly piv nrog rau lwm yam vuam flange.Nyob rau hauv ib puag ncig ntawm qhov kub thiab txias, lub threaded flange tsis haum rau kev siv, vim hais tias cov xov yog ib qho yooj yim kom xau tom qab thermal expansion thiab txias contraction.
