Yeeb Flange System
Piping flange yog hais txog cov flange siv rau cov kav dej hauv kev teeb tsa cov kav dej, thiab hais txog qhov nkag thiab qhov hluav taws xob flanges ntawm cov khoom siv thaum siv cov khoom siv.Muaj qhov ntawm lub flanges, thiab bolts ua rau ob lub flanges nruj nreem txuas.Cov flanges yog kaw nrog gaskets.Lub flange muab faib ua threaded kev twb kev txuas (threaded kev twb kev txuas) flange, vuam flange thiab clamp flange.Flanges yog siv los ua khub, hlau flanges tuaj yeem siv rau cov kav dej uas tsis tshua muaj siab, thiab welded flanges rau qhov siab ntawm ntau tshaj plaub kilograms.Lub gasket yog ntxiv ntawm ob lub flanges thiab tom qab ntawd nruj nrog bolts.Lub thickness ntawm flanges nrog sib txawv pressures yog txawv, thiab bolts lawv siv kuj txawv.Thaum cov twj tso kua dej thiab cov li qub txuas nrog cov kav dej, qhov chaw ntawm cov khoom siv thiab cov khoom siv no kuj tau ua rau cov duab flange sib raug, uas tseem hu ua flange kev sib txuas.Txhua qhov txuas txuas uas txuas nrog bolts nyob rau sab nraud ntawm ob lub dav hlau thiab raug kaw tib lub sijhawm feem ntau hu ua "flanges", xws li kev sib txuas ntawm cov kav dej cua.Cov khoom no tuaj yeem hu ua "flange parts".Txawm li cas los xij, qhov kev sib txuas no tsuas yog ib feem ntawm cov khoom siv, xws li kev sib txuas ntawm flange thiab lub twj tso kua dej, nws tsis zoo hu rau lub twj tso kua dej "flange parts".Cov me me, xws li li qub, tuaj yeem hu ua "flange parts".

3. Raws li machinery (JB) cov qauv kev lag luam: integral flange, taub qab vuam flange, phaj tiaj vuam flange, taub qab vuam nplhaib phaj xoob flange, tiaj vuam nplhaib phaj xoob flange, flanged nplhaib phaj xoob flange, flange npog.
4. Raws li lub teb chaws (GB) cov qauv: ib qho flanges, threaded flanges, taub qab vuam flanges, caj dab ca vuam flanges, caj dab socket vuam flanges, taub qab vuam nplhaib caj dab xoob flanges, phaj tiaj flanges Vuam flanges, taub qab vuam nplhaib phaj xoob flanges , tiaj vuam nplhaib phaj xoob flanges, flanged nplhaib phaj xoob flanges, flange npog.
WCB (carbon steel), LCB (tsis kub carbon steel), LC3 (3.5% nickel steel), WC5 (1.25% chromium 0.5% molybdenum steel), WC9 (2.25% chromium), C5 (5% chromium 0.5% molybdenum), C12 (9% chromium thiab 1% molybdenum), CA6NM (4 (12% chromium hlau), CA15 (4) (12% chromium), CF8M (316 stainless hlau), CF8C (347 stainless hlau), CF8 (304 stainless hlau) , CF3 (304L) Stainless hlau), CF3M (316L stainless hlau), CN7M (alloy steel), M35-1 (Monel), N7M (Haast Nickel Alloy B), CW6M (Hasta Nickel Alloy C), CY40 (Inconel) Tos.
Cov txheej txheem ntau lawm yog muab faib ua plaub hom: forging, casting, txiav thiab dov.
(1) Cam khwb cia flange thiab forged flange
Cov flange cam khwb cia muaj qhov zoo thiab qhov loj me, qhov ntim me me thiab tus nqi qis, tab sis muaj qhov tsis xws luag (pores, tawg, suav nrog);cov txheej txheem sab hauv ntawm lub casting yog tsis zoo nyob rau hauv streamline (yog hais tias nws yog ib feem, lub streamline yog phem);
Forged flanges feem ntau muaj cov ntsiab lus qis dua li cov flanges cam khwb cia thiab tsis yooj yim rau xeb.Forgings yog streamlined, muaj ib tug denser qauv, thiab muaj zoo mechanical zog dua cam khwb cia flanges;
Cov txheej txheem forging tsis raug kuj tseem yuav ua rau cov pob zeb loj lossis tsis sib xws, cov kab nrib pleb tawv tawv, thiab cov nqi forging siab dua cam khwb cia flanges.
Forgings tuaj yeem tiv taus siab dua shear thiab tensile zog dua li castings.
Qhov zoo ntawm castings yog tias lawv tuaj yeem tsim cov duab ntau dua thiab cov nqi qis dua;
Qhov kom zoo dua ntawm forgings yog tias cov qauv sab hauv yog sib xws, thiab tsis muaj teeb meem tsis xws luag xws li pores thiab inclusions hauv casting;
Los ntawm cov txheej txheem ntau lawm, qhov sib txawv ntawm cam khwb cia flange thiab forged flange yog txawv.Piv txwv li, centrifugal flange yog ib hom cam khwb cia flange.
Centrifugal flanges muaj nyob rau hauv precision casting txoj kev los tsim flanges.Piv nrog rau cov xuab zeb zoo tib yam casting, cov qauv ntawm no hom ntawm casting yog ntau finer, thiab zoo yog zoo dua qub.Nws tsis yooj yim rau cov teeb meem xws li cov qauv xoob, pores, thiab trachoma.
Ua ntej ntawm tag nrho cov, peb yuav tsum to taub yuav ua li cas lub centrifugal flange yog tsim, cov txheej txheem txheej txheem thiab cov khoom ntawm lub centrifugal casting los ua lub tiaj vuam flange, uas yog yus muaj los ntawm cov khoom yog ua los ntawm cov nram qab no cov txheej txheem:
① Muab cov khoom siv raw khoom xaiv rau hauv qhov nruab nrab zaus hluav taws xob qhov cub rau smelting, kom qhov kub ntawm cov hlau molten ncav cuag 1600-1700 ℃;
② Preheat cov pwm hlau rau 800-900 ℃ kom tswj tau qhov kub thiab txias;
③ Pib lub centrifuge, thiab ncuav cov hlau molten hauv kauj ruam ① rau hauv cov pwm hlau tom qab preheating hauv kauj ruam ②;
④ Lub casting yog ib txwm txias rau 800-900 ℃ thiab khaws cia rau 1-10 feeb;
⑤ Txias nrog dej kom ze rau qhov kub thiab txias, demould thiab tshem tawm cov casting.
