Dab tsi yog ibAluminium Flange?
Aluminium flange yog forged, machined, los yog fabricated txhuas tivthaiv uas tsim ib tug bolted kev twb kev txuas ntawm piping los yog khoom.
Lub flanged sib koom ua ke muaj xws li:
Yeeb → Flange → Gasket → Mating Flange → Bolts
Thaum cov bolts tau nruj, lub gasket compresses ntawm ob lub flange ntsej muag thiab muab khi rau qhov sib koom ua ke.
Flange feem ntau muaj:
Ib qho chaw nruab nrab (tshwj tsis yog qhov muag tsis pom flanges)
Lub ntsej muag sib khi (lub ntsej muag tiaj tus lossis tsa ntsej muag)
Bolt qhov tau teem rau ntawm lub voj voog bolt
Ib qho tshwj xeeb thickness
Ib qho kev sib txuas qauv txuam nrog flange hom
Vim li cas thiaj siv Aluminium Hloov Hlau?
Aluminium flanges raug xaiv thaum qhov hnyav, kev tiv thaiv corrosion, thiab cov khoom sib raug zoo tseem ceeb tshaj qhov siab tshaj plaws.
Qhov hnyav: Aluminium ntom yog li ntawm 2.70 g / cm³ - kwv yees li ib -thib peb ntawm steel (7.85 g / cm³). Rau cov tshuab uas muaj ntau lub flanged pob qij txha, qhov sib txawv ntawm qhov hnyav no ntxiv: kev tuav tau yooj yim dua, kev txhawb nqa sib dua, thiab cov nqi xa khoom qis dua.
Corrosion kuj: Feem ntau cov aluminium alloys tsim ib txheej oxide nyias (li 4 nm) ntawm qhov chaw uas rov tsim dua yog khawb. Qhov no ua rau muaj kev tiv thaiv zoo nyob rau hauv atmospheric thiab ntau qhov chaw dej tshiab. Tab sis txhuas tsis yog universally corrosion- pov thawj - seawater, tshuaj muaj zog, thiab galvanic kev sib cuag nrog hlau lossis tooj liab tuaj yeem ua rau muaj teeb meem loj. Alloy xaiv thiab ib puag ncig yuav tsum raug kuaj xyuas los ntawm rooj plaub.
Galvanic corrosion ceeb toom: Thaum ib qho txhuas flange hu rau lub flange steel, steel bolts, los yog tooj liab Cheebtsam nyob rau hauv lub xub ntiag ntawm noo noo, aluminium ua raws li lub anode thiab corrodes sai. Qhov no yog qhov txaus ntshai tiag tiag hauv kev sib xyaw- hlau tshuab. Siv cov insulating gaskets, lub tes tsho bolt, thiab cov ntxhua khaub ncaws kom tawg lub galvanic Circuit Court yog tias sib xyaw hlau tsis tuaj yeem zam tau.
Machineability: Aluminium machines huv si - bolt qhov, bores, kev cai PCDs, thiab tshwj xeeb thicknesses yog tswv yim los tsim.

Yog tias tus neeg siv khoom hais tias "Kuv yuav tsum kaw qhov kawg ntawm cov yeeb nkab," lub qhov muag tsis pom flange yog qhov pib.
Flange Type vs Flange Facing - Ob yam sib txawv
Flange hompiav qhia txog cov qauv kev sib txuas ntawm cov yeeb nkab (Slip-On, Weld Neck, Dig muag, thiab lwm yam).
Flange tigpiav txog qhov sealing nto:
Lub ntsej muag tiaj tus (FF)
Raised ntsej muag (RF)
Lwm yam kev taw qhia ntsej muag
Piv txwv li: "6061 Aluminium Slip- Ntawm Flange, DN150, Class 150, RF"
Slip- Ntawm=hom flange
RF=flange tig
Cov no yog ob qho kev qhia tshwj xeeb. Ob leeg yuav tsum tau hais thaum txiav txim los ntawm tus neeg muag khoom aluminium flange.
Yuav Ua Li Cas Xaiv Txoj Cai Aluminium Flange
Kauj Ruam 1: Cov yeeb nkab loj- Muab DN, NPS, lossis cov yeeb nkab OD thiab phab ntsa tuab. Rau cov kav dej tsis yog - qauv, cov yeeb nkab OD yog qhov tseem ceeb.
Kauj Ruam 2: Nruab nrab- Qhia tus neeg muag khoom seb lub flange yuav nqa li cas (dej, huab cua, dej txias, dej hiav txwv, cov dej ua haujlwm, thiab lwm yam). Tshuaj compatibility ntawm txhuas nyob ntawm qhov nruab nrab hnyav.
Kauj Ruam 3: Kub- Kub muaj feem xyuam rau cov khoom siv zog, tso cai siab, xaiv gasket, thiab bolting. Aluminium alloys poob lub zog siab tshaj li ntawm 150℃- paub meej tias qhov ntsuas ntawm koj qhov kev ua haujlwm kub.
Kauj Ruam 4: Siab- Qhia qhov tsim lossis kev ua haujlwm siab thiab chav kawm siab (Class 150, Class 300, PN10, PN16, thiab lwm yam). Tsis txhob xav tias chav kawm nominal sib npaug ntawm qhov tso cai siab hauv psi. Aluminium flanges muaj qhov siab qis dua - qhov ntsuas kub dua li cov flanges steel ntawm tib chav kawm - xa mus rau cov qauv siv tau rau qhov ntsuas qhov tseeb.
Kauj ruam 5: Flange hom- Siv cov kev cai sib txuas kom txo qis:
| Yog koj xav tau... | Xav txog... |
|---|---|
| General welded kev twb kev txuas | Nyem -On |
| Butt-weld / xav tau tsim | Weld caj dab |
| Cov yeeb nkab kaw | dig muag |
| Threaded yeeb nkab | Xov |
| Compact me me - tho welded kev twb kev txuas | Qhov (socket) Weld |
| Nruam dismantling / Stub End system | Lap Joint |
| Tank los yog kev cai fabrication | Phaj |
Qhov no yog ib lub moj khaum dav dav, tsis yog hloov pauv rau kev tsim engineering.

FAQ
Qhov twg aluminium flange yog qhov yooj yim tshaj rau nruab?
Slip- Ntawm flanges feem ntau yog qhov yooj yim tshaj - cov yeeb nkab hla ntawm flange, ces nws yog positioned thiab welded. Tab sis kev yooj yim installation nyob ntawm cov txheej txheem vuam thiab qhov yuav tsum tau ua, tsis yog hom flange xwb.
Qhov txawv ntawm Slip-On thiab Socket Weld flanges yog dab tsi?
Slip-Ntawm flange cia cov yeeb nkab hla tag nrho. Lub qhov (socket Weld flange) muaj lub qhov (socket) rov qab uas cov yeeb nkab haum rau hauv - cov yeeb nkab tsis dhau. Ob leeg yog welded, tab sis qhov sib koom geometry txawv.
Dab tsi yog qhov txawv ntawm Slip-On thiab Lap Joint flanges?
Slip-Ntawm flange yog welded ncaj qha rau cov yeeb nkab. Lub Lap Joint flange swb hla Stub End uas yog welded rau cov yeeb nkab, tso cai rau lub flange tig kom yooj yim ntsia liaj qhov rooj - qhov sib npaug thiab tshem tawm.
Qhov twg flange kaw lub yeeb nkab kawg?
Ib qhov muag tsis pom Flange. Nws tsis muaj qhov nruab nrab bore thiab bolts rau mating flange kom kaw qhov qhib.
Puas yog aluminium flanges haum rau seawater?
Qee cov alloys - tshwj xeeb tshaj yog 5083 - yog siv nyob rau hauv marine ib puag ncig. Tab sis kev pabcuam dej hiav txwv yuav tsum tau ua tib zoo xaiv cov alloy, kev tshuaj xyuas tsim, thiab kev ntsuam xyuas corrosion. Muab qhov nruab nrab, kub, thiab siab ua ntej xaiv cov khoom. Tsis yog txhua qhov txhuas alloys yog marine-qib.
Aluminium flanges puas tuaj yeem kho tau?
Yog lawm. Kev cai qhov ntev xws li txoj kab uas hla, qhov tob, qhov tuab, lub voj voog lub voj voog, ntsia liaj qhov rooj - qhov ntau thiab qhov loj, thiab lub ntsej muag tuaj yeem tsim, raws li kev tsim khoom. Daim duab kos duab yog qhov zoo tshaj plaws kom tsis txhob muaj qhov yuam kev.
Tus qauv loj tshaj plaws GNEE tuaj yeem muab tau li cas?
Standard aluminium flange qhov ntau thiab tsawg yog muaj txog DN350. Qhov ntau thiab tsawg tuaj yeem raug kho raws li cov duab kos thiab qhov yuav tsum tau ua.
Puas yog aluminium hnyav hnyav rau flanges?
Yog lawm. Aluminium hnyav txog 2.70 g / cm³, kwv yees li ib -feem peb ntawm steel (7.85 g / cm³). Rau cov tshuab uas muaj ntau lub flanged pob qij txha - xws li loj - txoj kab uas hla piping lossis marine installations - qhov hnyav hauv kev tuav, kev txhawb nqa, thiab kev xa khoom tuaj yeem yog qhov tseem ceeb.
Yuav ua li cas yog galvanic corrosion?
Thaum lub aluminium flange tiv tauj cov hlau los yog tooj liab nyob rau hauv lub xub ntiag ntawm noo noo, txhuas ua raws li cov anode thiab corrodes sai. Qhov no yog qhov txaus ntshai tiag tiag hauv kev sib xyaw- hlau tshuab. Siv cov insulating gaskets, lub tes tsho bolt, thiab cov ntxhua khaub ncaws kom tawg lub galvanic Circuit Court yog tias sib xyaw hlau tsis tuaj yeem zam tau.
