Cov tsos xim thiab tso cai sib txawv ntawm Loj-inch Flanges
Loj-inch flanges yog dav siv nyob rau hauv ntau yam lag luam xws li tshuab, tshuaj, cua zog, thiab kev kho dej khib nyiab. Lawv nrov heev ntawm cov neeg siv. Loj-inch flanges yog tsim los siv ob txoj kev tsim khoom loj: dov thiab forging. Cov flanges loj heev feem ntau yog tsim los ntawm dov. Cov ntaub ntawv siv rau qhov loj-inch flanges suav nrog carbon steel, stainless hlau, thiab hlau alloy.
Cov xim ntawm qhov loj-inch flanges tsis cuam tshuam rau lawv qhov zoo; nws tsuas yog cov xim ntawm cov roj tiv thaiv xeb siv rau ntawm lawv qhov chaw, tsis yog xim ntawm cov khoom siv nws tus kheej. Txawm li cas los xij, cov khoom tsim khoom hnub tuaj yeem txiav txim siab los ntawm cov xim ntawm flange nto. Yog tias cov khoom tau khaws cia ntev ntev, cov roj tiv thaiv xeb tuaj yeem nkag mus rau hauv cov khoom, ua rau nws muaj hnub nyoog nrog cov xim qub. Txawm li cas los xij, qhov no tsis txhais tau tias cov khoom lag luam tsis zoo. Qhov tseeb, qee cov khoom qub uas tau tsim yav dhau los yuav muaj qhov zoo dua li qee yam khoom siv tam sim no. Raws li nrog ntau lwm cov lag luam, qhov zoo ntawm cov khoom tam sim no feem ntau tsis zoo li yav dhau los vim tias cov txiaj ntsig tam sim no yog qhov tseem ceeb, ua rau muaj kev cuam tshuam hauv cov khoom zoo. Nws cia siab tias cov tuam ntxhab thiab cov neeg siv khoom hauv kev lag luam flange yuav koom tes los txhim kho qhov teeb meem tsis txaus ntseeg no.
Hais txog qhov tso cai qhov sib txawv ntawm qhov ntsia hlau qhov hauv qhov loj-inch flanges, muaj qhov ntsuas ntawm qhov siab ntev. Txawm hais tias muaj qee qhov sib txawv, nws yuav tsum tsis txhob cuam tshuam rau kev teeb tsa thiab siv cov khoom. Hauv kev tsim khoom, cov flanges me me muaj qhov sib txawv me me nyob rau hauv txoj hauj lwm ntawm lub qhov ntsia hlau, thaum cov flanges loj dua yuav muaj qhov sib txawv loj dua. Yog vim li cas rau cov kev sib txawv no tshaj tus qauv yog tias, nyob rau hauv tej yam xwm txheej tshwj xeeb nrog rau lub sij hawm nruj, ntau flanges feem ntau stacked ua ke kom drilled ib txhij. Hauv cov xwm txheej zoo li no, cov cuab yeej laum feem ntau yuav nco lawv cov cim. Nws yog lub npe hu hais tias yog hais tias lub qhov yog drilled ib tug los ntawm ib tug, lub deviation yuav tsis tshaj tus qauv. Txawm li cas los xij, thaum ob peb lub flanges tau muab tso ua ke, qhov chaw ntawm lub qhov tuaj yeem hloov tau yooj yim.
Feem ntau hom flanges loj-ntev yog plam-ntawm flanges thiab weld caj dab flanges. Threaded flanges feem ntau tsis suav hais tias loj-inch flanges. Hauv kev tsim khoom thiab kev muag khoom, slip-on flanges account rau ib qho tseem ceeb. Slip-on loj-inch flanges thiab weld caj dab loj-inch flanges muaj cov qauv sib txawv thiab daim ntawv thov ntau yam, txhua tus muaj cov yam ntxwv thiab qhov zoo. Yog li ntawd, nws yog ib qho tsim nyog los xyuas kom meej tias flanges ua haujlwm tseem ceeb raws li lawv qhov kev siv. Loj-inch slip-on flanges muaj qhov tsis zoo rigidity thiab haum rau cov ntawv thov uas tsis tshua muaj siab (P Tsawg dua lossis sib npaug li 4 MPa). Weld caj dab flanges, tseem hu ua high-caj dab flanges, muaj rigidity zoo thiab haum rau high-pressure thiab high-temperature.
Flanges tuaj yeem muab faib ua peb hom kev sib khi: tiaj tus sealing nto (tsim rau qis-siab, tsis muaj tshuaj lom neeg tawm), tsa ntsej muag sealing nto (tsim rau qis rau nruab nrab siab), thiab groove sealing nto (tsim rau cov nplaim taws, tawg, tshuaj lom neeg tawm xov xwm, thiab kev siv hluav taws xob siab).
SINO SPECIAL METAL muab ntau hom thiab cov ntaub ntawv ntawm cov yeeb nkab fittings, flanges, thiab cov kav dej. Peb yog cov chaw muag khoom ntseeg siab, thiab peb txais tos cov lus nug thiab kev yuav khoom.
