Cov kav dej hlau uas muaj qhov sib xyaw ua ke flanges yog ib hom yeeb nkab uas siv rau hauv ntau yam kev siv, suav nrog cov khoom siv dej, cov kav dej phwj tuaj, thiab cov kav dej.Cov kav dej no yog tsim los ntawm cov hlau nplaum, uas yog ib hom cam khwb cia hlau uas tau txhim kho lub zog thiab ductility.
Integrally cam khwb cia flange yog ib feem ntawm cov yeeb nkab uas yog cam khwb cia li ib thooj nrog cov yeeb nkab lub cev.Qhov no txhais tau hais tias lub flange tsis yog ib qho kev sib cais uas yog welded los yog bolted rau cov yeeb nkab, tab sis yog ib qho tseem ceeb ntawm cov yeeb nkab nws tus kheej.Qhov kev tsim no muab ntau qhov zoo, suav nrog:
1. Txhim kho lub zog: Qhov sib xyaw ua ke flange muab kev sib txuas ntawm cov yeeb nkab thiab flange, vim tias tsis muaj cov ntsiab lus tsis muaj zog lossis muaj peev xwm xau.
2. Txo lub sijhawm teeb tsa: Lub flange integrally tshem tawm qhov xav tau ntawm cov flange cais, uas tuaj yeem txuag lub sijhawm thaum lub sijhawm teeb tsa.
3. Kev saib xyuas qis dua: Lub flange integrally cam khwb cia txo qhov kev pheej hmoo ntawm kev xau thiab lwm yam teeb meem txij nkawm, uas tuaj yeem txuag nyiaj ntau dhau lub neej ntawm cov yeeb nkab.
Cov kav dej hlau uas muaj qhov sib xyaw ua ke flanges muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab kev ntsuas siab, ua rau lawv haum rau ntau yam kev siv.Lawv kuj sib xws nrog ntau yam kev sib koom ua ke, suav nrog kev thawb-rau, mechanical, thiab flanged pob qij txha.
Ductile hlau (DI) cov kav dej nrog cov flanges sab hauv yog ib hom yeeb nkab uas feem ntau siv rau hauv cov dej thiab cov kav dej phwj tuaj.Cov kav dej no yog tsim los ntawm cov hlau nplaum, uas yog ib hom hlau uas tau kho nrog cov magnesium me me kom nws hloov tau yooj yim thiab ruaj khov dua li cov hlau cam khwb cia.
Internally cam khwb cia flanges yog ib qho tseem ceeb ntawm cov kav dej no, vim lawv tso cai rau kev sib txuas yooj yim rau lwm cov kav dej thiab fittings.Cov flanges raug nrum ncaj qha rau hauv cov yeeb nkab thaum lub sijhawm tsim khoom, uas ua kom muaj kev sib txuas nruj thiab ruaj ntseg uas tiv taus cov xau thiab lwm yam kev puas tsuaj.
DI cov kav dej nrog cov flanges sab hauv kuj paub txog lawv lub zog siab thiab ua haujlwm ntev, uas ua rau lawv zoo tagnrho rau kev siv nyob rau hauv ib puag ncig hnyav thiab kev siv qhov twg cov kav dej yuav raug hnyav los yog muaj kev kub ntxhov.Lawv kuj muaj peev xwm tiv taus corrosion thiab lwm yam kev puas tsuaj, uas yuav pab kom ntev lawv lub neej thiab txo cov nqi kho lub sijhawm.
Zuag qhia tag nrho, DI cov kav dej nrog cov flanges sab hauv yog ib qho kev txhim khu kev qha thiab cov nqi tsim nyog rau kev siv dej ntau thiab dej phwj tuaj.Lawv muab ntau cov txiaj ntsig zoo dua li lwm cov kav dej, suav nrog kev ua kom muaj zog, ua haujlwm ntev, thiab tiv thaiv kev puas tsuaj thiab corrosion.
