Kev tsim steel yeeb nkab nrog Flange
Kev tsim steel yeeb nkab nrog Flangeyog ib qho tshwj xeeb cov qauv thiab cov kua dej- tuav cov khoom muaj xws li carbon, stainless, los yog galvanized steel raj nrog ncig steel rims (flanges) mus tas li welded rau ib los yog ob qho tag nrho. Cov flanges no yog precision-drilled nrog standardized bolt qhov (raws liASME B16.5, EN 1092-1, lossis DINcov qauv) tso cai rau kev ruaj ntseg, ntsia liaj qhov rooj - thiab - cov neeg kho tshuab kev sib txuas ntawm cov yeeb nkab, li qub, lossis cov khoom siv.
Tsis zoo li cov pob qij txha txuas mus tas li, cov kav dej flanged muab cov txheej txheem siab nruj thaum tso cai rau kev sib dhos sai thiab tsis yog - rhuav tshem, ua rau lawv tsis muaj qhov tseem ceeb rau kev siab - cov kav dej siab, HVAC systems nyob rau hauv siab - nce vaj tsev, thiab hnyav - lub luag haujlwm ntawm kev tsim kho vaj tse.

Txoj kev sib txuas ntawm Flange Pipe
Cov kav dej flange siv cov khoom siv "sandwich" kev sib txuas uas tsis xav tau ntawm - qhov chaw vuam:
Kev sib tw:Ob lub flanged yeeb nkab kawg raug coj los ua ke, kom ntseeg tau tias lub qhov ntsia hlau tau zoo sib xws.
Sealing (ntaub qhwv):Lub gasket (ua los ntawm roj hmab, EPDM, PTFE, los yog kauv lub qhov txhab hlau) yog muab tso rau ntawm ob lub flange ntsej muag los tsim ib tug leak- pov thawj foob.
Bolting:Siab - lub zog bolts tau dhau los ntawm lub qhov thiab nruj nrog cov txiv ntseej hauv lub hnub qub qauv kom ntseeg tau tias txawm tias muaj kev sib faib siab.
Disassembly:Kev sib txuas tuaj yeem tawg yooj yim los ntawm kev tshem cov bolts, tso cai rau kev saib xyuas lossis kho dua tshiab ntawm kev tsim kho.
Cov ntaub ntawv ntawm Flange Pipe
Tube Substrate:
Carbon Steel:ASTM A106 Gr. B, ASTM A53 Gr. B, Q235B, Q355B (feem ntau yog siv rau kev tsim qauv).
Stainless hlau:SS304/304L, SS316/316L (rau corrosive ib puag ncig).
Galvanized hlau:Ua ntej-galvanized lossis Kub-dip galvanized rau kev tiv thaiv xeb.
Flange Khoom siv:
Forged hlau:ASTM A105 (Standard for carbon steel siab systems).
Stainless hlau:ASTM A182 F304 / F316 / ASTM A182 / ASTM A182 F304 thiab F316
Hlau phaj:Cov pa roj carbon steel phaj rau qis - kev siv cov qauv siv.
Daim ntawv thov
High-Rise Building Infrastructure:Kev tua hluav taws tua hluav taws, cov kab dej txias rau HVAC, thiab cov kav dej ntsug.
Structure Support & Piling:Siv raws li cov qauv kab lossis kev txhawb nqa ib ntus hauv kev tsim kho choj thiab subway qhov twg cov ntu yuav tsum tau bolted ua ke.
Municipal Water Systems:Loj txoj kab uas hla dej xa mus thiab cov chaw kho dej phwj tuaj.
Kev tsim kho ib ntus Piping:Cov kab dej thiab cua tshuab ntawm cov loj - qhov chaw tsim kho uas yuav tsum tau tsiv los yog rov siv dua.
Muaj cua txias:Piping tes hauj lwm rau factories thiab fais fab nroj tsuag.
Nta
Kev kho yooj yim:Tso cai rau kev tshem tawm cov yeeb nkab tshwj xeeb rau kev ntxuav lossis tshuaj xyuas yam tsis tau txiav cov yeeb nkab.
High Structural Rigidity:Lub flange ua raws li lub tsho muaj zog, muab lub zog ntxiv ntawm kev sib koom ua ke tiv thaiv kev khoov thiab kev co.
Tsis Nyob ntawm -Vuam qhov chaw:Qhov zoo tshaj plaws rau "kub- ua haujlwm txwv tsis pub ua haujlwm" thaj chaw lossis qhov chaw uas cov kws txawj welder tsis muaj, ua rau kev txhim kho sai.
Kev Tiv Thaiv Leak Zoo:Thaum ua ke nrog cov roj gasket thiab lub zog kom raug, kev sib txuas flanged yog qhov kev ntseeg siab rau siab -cov kua xa tawm.
Corrosion Resistance:Feem ntau cov kav dej flange yog kub-dip galvanized (HDG), muab kev tiv thaiv zoo tshaj plaws tiv thaiv av thiab huab cua noo.

FAQ
Cov kav dej flange puas tuaj yeem siv hauv av?
Yog lawm, cov kav dej flange tuaj yeem siv hauv av, tab sis lawv yuav tsum tau ceev faj tshwj xeeb:
Kev tiv thaiv corrosion:Vim hais tias bolts thiab txiv ntseej muaj qhov cuam tshuam rau cov av corrosion, qhov sib koom ua ke yuav tsum tau tiv thaiv sivPetrolatum daim kab xev (Denso daim kab xev), epoxy coatings, los yog hnyav -lub luag hauj lwm kub-shrink tes tsho.
Maintenance Access:Lawv feem ntau yog siv rau hauvvalve pits los yog manholesqhov twg qhov sib koom ua ke tseem siv tau rau kev tshuaj xyuas thiab nruj.
Av Stability:Tsis zoo li cov welded los yog hloov tau yooj yim, flange pob qij txha yog nruj. Lawv yog qhov zoo tshaj plaws rau cov av ruaj khov, vim tias cov av tseem ceeb tuaj yeem ua rau muaj kev ntxhov siab heev ntawm cov bolts thiab ua rau cov xau.
