Sealing kev twb kev txuas thiab siv txoj kev siab flange

Flange Supplier-GNEE

Muaj peb hom high-pressure flange sealing nto: tiaj sealing nto, haum rau cov xwm txheej uas lub siab tsis siab thiab nruab nrab yog huv si; concave thiab convex sealing nto, haum rau cov xwm txheej uas lub siab yog me ntsis siab dua; nplaig-thiab-groove sealing nto, haum rau flammable, lom, xwm txheej nrog siab nruab nrab thiab siab. Kev sib cuag dav ntawm lub siab-siab flange gasket thiab sealing nto yog nqaim heev (kab tiv tauj), thiab kev ua tiav ntawm sealing nto thiab gasket yog siab. Feem ntau cov flanges muaj xws li tiaj vuam flanges thiab taub qab vuam flanges. Cov roj hmab zoo tib yam yog tsim rau lub sijhawm uas qhov kub thiab txias qis dua 120 degree; Asbestos roj hmab gaskets haum rau cov xwm txheej uas cov dej vapor kub qis dua 450 degree, cov roj kub qis dua 350 degree, thiab lub siab qis dua 5MPa. Rau kev corrosiveness nruab nrab, feem ntau siv acid-resistant asbestos board.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

High-pressure flange kev twb kev txuas yog ib tug detachable kev twb kev txuas. Raws li cov khoom sib txuas, nws tuaj yeem muab faib ua lub thawv flange thiab cov yeeb nkab flange. Raws li cov qauv txheej txheem, muaj ib qho flanges, voj flanges thiab threaded flanges. Hauv cov cuab yeej siv hluav taws xob thiab cov kav dej, lub lens-puab lossis lwm yam zoo li cov hlau gaskets ua los ntawm tooj liab, aluminium, No. 10 steel, thiab stainless hlau yog siv. Lub siab-siab flange muaj qhov tsis zoo rigidity thiab haum rau cov xwm txheej uas lub siab p Tsawg dua los yog sib npaug rau 4MPa; lub siab-siab flange, tseem hu ua high-caj dab flange, muaj ntau dua rigidity thiab haum rau cov xwm txheej uas lub siab thiab kub siab dua. High-pressure flange gasket yog lub nplhaib ua los ntawm cov khoom siv uas tuaj yeem tsim cov yas deformation thiab muaj zog sib xws.

Thaum ua cov flanges, peb yuav tsum xub to taub tias xws li ib feem ntawm nws tus kheej tej zaum yuav muaj xws li tsis xws luag thaum lub sij hawm vuam txheej txheem. Yog hais tias qhov vuam tsis xws luag ntawm stainless hlau flanges yog qhov hnyav, lawv tau ua tiav los ntawm tes. Mechanically polished, txoj kev polishing no yog siv los them nyiaj. Hais txog kev hais lus, nws tuaj yeem tsim cov cim polishing, uas yuav ua rau ntau dua lossis tsawg dua qhov tsis sib xws, yog li cuam tshuam ncaj qha rau cov tsos ntawm tag nrho cov khoom siv.

Kev sib tsoo thiab polishing ntawm flange yuav tsis sib npaug thaum ua haujlwm. Nyob rau hauv no txoj kev, thaum lub sij hawm ib tug series ntawm pickling thiab passivation txheej txheem, nws yog ib qhov nyuaj rau ua tau ib tug ntau yam kev kho mob nyhuv rau workpieces nrog ib tug kuj loj cheeb tsam. Yog li ntawd, yog tias nws tsis tuaj yeem Yog tias qhov txiaj ntsig no ua tiav, nws yuav siv sijhawm ntau lub sijhawm thaum ua haujlwm. Hais txog kev hais lus, cov khoom siv rau qee cov khoom siv pabcuam kuj yog siab heev.

Kuj tseem muaj teeb meem ntsib thaum lub sijhawm ua haujlwm. Tej zaum yuav muaj qee qhov khawb ntawm lub flange. Cov khawb no nyuaj heev kom tshem tawm. Yog li ntawd, thaum lub sij hawm tag nrho passivation, nyob rau hauv tej yam kev mob ntawm corrosive media, feem ntau yuav muaj ib tug series ntawm tshuaj corrosion tshwm sim, uas ua rau ib co xeb.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Yog li, thaum cov teeb meem no tshwm sim thaum lub sij hawm ua flange, peb yuav tsum daws lawv li cas? Ua ntej tshaj plaws, peb yuav tsum xyuam xim thaum xaiv cov khoom. Peb yuav tsum xaiv cov khoom sib txawv raws li cov xwm txheej sib txawv, thiab tom qab ntawd ua cov txheej txheem kom raug.

Tsuav peb nkag siab ntau yam kev lag luam niaj hnub no, tib neeg yuav pom tias nyob rau hauv cov kev lag luam zoo li no, peb tseem yuav tsum tau siv qee yam khoom siv, tshwj xeeb tshaj yog kev sib txuas ntawm cov shafts. , tab sis yuav ua li cas ua kom tiav qhov kev sib txuas, koj yuav tsum siv qhov chaw xws li flanges nyob rau lub sijhawm no, kom qhov kev sib txuas tam sim no ntawm cov yeeb nkab kawg tuaj yeem ua tiav.

Nws tuaj yeem hais tias cov khoom zoo li no tuaj yeem siv tau zoo rau kev sib txuas ntawm qee cov yeeb nkab kawg, lossis rau kev sib txuas ntawm ob lub cuab yeej, thiab tau dhau los ua qhov sib txuas siv hauv ntau qhov kev lag luam. Nws yog qhov tseeb vim tias qhov tshwm sim ntawm cov khoom seem uas tam sim no cov neeg tsis tas yuav txhawj xeeb txog cov teeb meem kev sib txuas thaum txuas cov khoom siv.

Kev sib txuas ntawm high-pressure flange thiab cov raj xa dej yog thawj zaug ntxig cov yeeb nkab rau hauv lub qhov ntawm lub flange mus rau qhov tsim nyog, thiab tom qab ntawd lap weld. Stainless hlau flange yog ib hom ca vuam flange. Yog li, peb yuav tsum xyuam xim rau dab tsi thaum siv stainless hlau flange? Cov neeg ua haujlwm ntawm cov chaw tsim khoom flange yuav qhia rau koj txog kev ceev faj rau kev siv flanges.

1. Lub hardened American standard flange ntawm chromium stainless hlau ca vuam flange yeeb nkab fittings tom qab vuam yog loj dua thiab nquag tawg. Yog tias tib hom chromium stainless hlau electrode (G202, G207) yog siv rau vuam, preheating saum 300 degree thiab qeeb txias ntawm txog 700 degree tom qab vuam yuav tsum tau. Yog tias qhov vuam tsis tuaj yeem raug kho tom qab vuam kub, stainless hlau tiaj vuam flange yeeb nkab haum electrodes (A107, A207) yuav tsum tau siv.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. Thaum vuam stainless hlau tiaj vuam flange yeeb nkab fittings, carbides yuav precipitate vim rov ua cua sov, txo cov durability thiab txhua yam khoom.

3. Txhawm rau tiv thaiv qhov muag ntawm qhov muag vim qhov cua sov ntawm lub flange npog, qhov vuam tam sim no yuav tsum tsis txhob loj dhau, uas yog li ntawm 20% tsawg dua li cov pa roj carbon steel electrodes. Lub arc yuav tsum tsis txhob ntev dhau, thiab cov interlayers yuav txias sai sai. Ib qho nqaim weld hlaws yog nyiam.

4. Lub vuam pas nrig yuav tsum khaws cia kom qhuav thaum siv. Hom titanium-calcium yuav tsum tau qhuav ntawm 150 degree rau 1 teev, thiab qis-hydrogen hom yuav tsum tau qhuav ntawm 200-250 degree rau 1 teev (tsis tuaj yeem qhuav ntau zaus, txwv tsis pub cov txheej yuav yooj yim tawg thiab tev. ) txhawm rau tiv thaiv cov txheej txheem ntawm vuam pas nrig yog daig nrog cov roj thiab lwm yam av, thiaj li tsis ua kom cov pa roj carbon ntau ntawm cov vuam thiab cuam tshuam rau qhov zoo ntawm cov vuam.
