Disadvantages ntawm xoob flange nrog tiaj vuam nplhaib:
Tsawg siab.
2. Tsawg zog ntawm lub nplhaib vuam (tshwj xeeb tshaj yog thaum lub thickness tsawg dua 3 hli)
Nws yog los txuas ob lub raj xa dej, fittings lossis cov khoom siv, thiab forging flange kev twb kev txuas yog ib txoj hauv kev tseem ceeb rau kev tsim cov kav dej. Forged flange kev twb kev txuas yog ib qho yooj yim mus use thiab muaj peev xwm tiv taus siab dua. Nyob rau hauv industrial pipelines, forged flange kev twb kev txuas yog dav siv. Hauv tsev, cov yeeb nkab txoj kab uas hla yog me me thiab tsis tshua muaj siab, thiab kev sib txuas ntawm flange stamping luj tshib yog pom tsis tau. Yog tias nws nyob hauv chav boiler lossis qhov chaw tsim khoom, cov kav dej flanged thiab cov khoom siv nyob txhua qhov chaw. Cov ntsiab lus chromium yog {{0}}.1 feem pua -0.5 feem pua (forged flanges feem ntau tsis muaj chromium), cov ntsiab lus carbon yog qis dua 1.0 feem pua thiab forged flanges yog tsim los ntawm high- kub forging, txawm hais tias qee qhov forged flanges muaj qhov tawv tawv (HRC) Nws tuaj yeem ncav cuag ntau dua 56 (txheej txheej hardening tsuas yog li 15 hli). Vim tias qhov tsis zoo ntawm lub forged flange, qhov hardness ntawm cov tub ntxhais feem ntau tsuas yog ntau tshaj 30 degrees. Raws li ib txwm muaj, lub forged flange feem ntau yog dej quenched.
Qhov zoo ntawm lub tiaj vuam nplhaib xoob flange
Kev txuag nqi. Thaum cov khoom siv yeeb nkab yog tshwj xeeb thiab kim, nws yog kim heev rau vuam flanges ntawm tib cov khoom.
2. Nws tsis yooj yim rau kev vuam lossis kev ua haujlwm lossis xav tau lub zog siab. Xws li cov yeeb nkab yas, iav steel yeeb nkab thiab lwm yam.
3. Yooj yim tsim. Piv txwv li, nws tsis yog ib qho yooj yim los kho qhov flange bolt qhov thaum lub sij hawm kev sib txuas los yog tiv thaiv flange bolt qhov ntawm cov cuab yeej los ntawm kev hloov mus rau yav tom ntej.
Nws yog ib qho flange txav tau, uas feem ntau yog txuam nrog cov khoom siv dej thiab cov kav dej fittings (feem ntau ntawm cov pob qij txha expansion). Thaum lub Hoobkas tawm ntawm lub Hoobkas, muaj ib lub flange ntawm txhua qhov kawg ntawm kev sib koom ua ke, uas yog ncaj qha mus rau cov kav dej thiab cov khoom siv hauv qhov project nrog bolts. Lub hom phiaj ntawm kev siv lub tiaj tiaj vuam nplhaib xoob flanges feem ntau yog kom txuag tau cov ntaub ntawv. Nws cov qauv muab faib ua ob ntu. Ib qho kawg ntawm cov yeeb nkab txuas nrog cov yeeb nkab, lwm qhov yog ua los ntawm flange, thiab flange ib feem yog lub tes tsho ntawm flanging. Lub flange yog ua los ntawm cov khoom siv qis, thaum cov yeeb nkab siv cov khoom siv tib yam li cov yeeb nkab kom txuag tau cov khoom.
