Nyob rau hauv flange casting, kua hlau yog ntim rau hauv pwm thaum tig thiab solidifying. Flange casting muaj cov yam ntxwv hauv qab no: cov hlau ua kua tuaj yeem tsim tau qhov chaw ywj pheej xaiv hollow cylindrical nto hauv cov pwm, tso cai rau cov khoom siv hollow yam tsis muaj lub hauv paus, uas ua kom yooj yim rau kev tsim thiab tswj cov txheej txheem ntawm lub tes tsho thiab cov yeeb nkab fittings. Qhov no ua rau cov txheej txheem casting, txhim kho kev tsim khoom, thiab txo cov nqi. Vim yog qhov kev txiav txim ntawm lub zog centrifugal, cov khoom ntim tau zoo tuaj, thiab cov pa roj carbon monoxide thiab cov khoom tsis yog xim hlau tau yooj yim tshem tawm ntawm cov kua hlau. Flange castings muaj cov qauv tuab thiab cov kws kho mob zoo, tshem tawm cov khoom siv nchuav thiab hlau, ua kom muaj kev siv cov khoom siv hlau. Lub zog centrifugal tsim los ntawm cov kua hlau thaum lub sij hawm sib txawv ntawm kev sib hloov ua kom zoo dua lub peev xwm ntawm cov hlau. Yog li ntawd, txoj kev flange casting tuaj yeem siv los tsim cov alloys thiab nyias-walled castings nrog cov dej tsis zoo.
Yog tias qhov teeb meem ntawm flange to tsis daws tam sim ntawd, qhov xau yuav nthuav dav sai nyob rau hauv qhov kev txiav txim siab ntawm qhov nruab nrab, ua rau cov khoom poob, kev puas tsuaj rau qhov chaw tsim khoom, nres ntau lawm, thiab ua rau muaj kev puas tsuaj loj. Yog tias qhov nruab nrab xau yog tshuaj lom, tawg, lossis tawg, nws tuaj yeem ua rau muaj tshuaj lom, hluav taws kub, lossis tawg. Corrosion yog ib qho kev sib tw tsis tu ncua hauv kev lag luam niaj hnub no, raws li cov yam ntxwv xws li corrosive media, kub, siab, thiab kev co inevitably ua rau xau. Flange to tuaj yeem tshwm sim vim qhov kev sib khi ntawm qhov loj me yuam kev, kev laus sealing Cheebtsam, lossis kev teeb tsa tsis raug thiab fastening.
Hauv qee qhov kev lag luam ib txwm muaj, qhov kev daws teeb meem rau flange to yog hloov cov khoom sib khi thiab siv cov sealant, lossis hloov cov flange thiab cov yeeb nkab. Txawm li cas los xij, txoj kev no muaj cov kev txwv tseem ceeb. Qee qhov dej xau raug txwv los ntawm kev nyab xeeb ntawm kev ua haujlwm thiab nyob ib puag ncig. Txhawm rau tshem tawm cov teeb meem kev nyab xeeb thiab txuag nqi txij nkawm, tam sim no peb tuaj yeem siv cov kev daws teeb meem polymer sib xyaw. Txoj kev no yog qhov zoo tagnrho, tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas muaj hluav taws kub thiab tawg, qhov uas nws qhia tau qhov zoo. Polymer composite technology muab cov txiaj ntsig ntawm kev tsim kho yooj yim, kev nyab xeeb, thiab tus nqi qis.
Qhov tseem ceeb ntawm kev siv flanges yog nyob rau hauv lawv cov kev ua tau zoo sealing, uas ua kom muaj txiaj ntsig zoo ntawm kev ua haujlwm ntawm tag nrho cov kav dej. Lawv tsis tsuas yog txhim kho kev sib khi zoo ntawm lub cev tab sis kuj tso cai rau kev ua haujlwm zoo. Flanges yog cov khoom tshwj xeeb nrog cov kev ntsuas sib txawv. Pipeline siab sib txawv, thiab yog li ua cov khoom sib txuam, ntim, thiab cov khoom siv. Txawm li cas los xij, flanges yog cov khoom tseem ceeb hauv engineering, ua lub luag haujlwm tshwj xeeb.
