Taw qhia:
Flanges ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam, ua raws li cov khoom sib txuas uas ua kom yooj yim sib dhos thiab disassembly ntawm cov kav dej. Txawm hais tias koj yog tus kws tshaj lij engineer lossis tsuas yog xav paub txog cov tshuab flanges, qhov blog no nyob ntawm no los muab kev nkag siab tob rau koj ntawm lawv cov yam ntxwv thiab ntau hom. Yog li cia peb dhia dej!
Cov yam ntxwv ntawm Flanges:
Flanges muaj ntau yam tseem ceeb uas ua rau lawv zoo tagnrho rau lawv cov kev xav tau. Ua ntej, lawv cov ntaub ntawv tsim kho feem ntau yog xaiv rau lawv lub zog siab, xws li carbon steel, stainless hlau, lossis hlau alloy. Qhov no ua kom durability thiab tsis kam mus rau ntau yam corrosive ib puag ncig. Tsis tas li ntawd, flanges yog tsim los tiv thaiv kev kub siab, ua rau lawv cov khoom tseem ceeb hauv kev lag luam cuam tshuam nrog cov kua dej lossis roj. Tsis tas li ntawd, flanges tau paub txog lawv cov khoom sib khi zoo heev, tiv thaiv kev xau thiab ua kom muaj kev ncaj ncees ntawm cov yeeb nkab sib txuas.
Hom Flanges:
1. Integral Flange (IF):
Ib qho flange, tseem hu ua IF, yog ib qho flange uas yog forged los yog nrum nrog cov yeeb nkab. Nws tsis xav tau kev sib txuas ntxiv, ua rau nws yog qhov kev xaiv nrov rau cov kav dej me me lossis cov tshuab tsis tshua muaj siab.
2. Threaded Flange (Th):
Threaded flanges muaj cov xov sab hauv uas tso cai rau lawv tuaj yeem ntsia tau rau hauv cov yeeb nkab threaded kawg. Lawv feem ntau yog siv nyob rau hauv lub tshuab uas tsis tshua muaj siab los yog thaum yuav tsum tau disassembly nquag.
3. Phaj Flat Vuam Flange (PL):
Lub phaj-flat vuam flange, tseem hu ua PL, yog welded ncaj qha mus rau hauv cov yeeb nkab kawg, kom ntseeg tau tias muaj kev ruaj ntseg thiab xau-pov thawj kev sib txuas. Nws yog feem ntau siv hauv kev lag luam uas yooj yim nkag tau rau kev tshuaj xyuas lossis tu.
4. Butt Vuam Flange nrog txoj kab uas hla (WN):
Butt welding flanges nrog ib txoj kab uas hla, sau tias yog WN, yog siv nyob rau hauv high-pressure thiab tseem ceeb daim ntaub ntawv uas lub zog ntawm lub sib koom ua ke yog qhov tseem ceeb. Cov txheej txheem vuam txuas ncaj qha rau vuam cov yeeb nkab thiab flange, muab lub zog zoo kawg nkaus thiab kev ntseeg siab.
5. Flat Vuam Flange nrog caj dab (SO):
Flat welding flanges nrog caj dab, los yog SO flanges, feature lub caj dab tsa uas pab txhim kho lub zog ntawm cov qauv thiab muaj zog tiv thaiv kom khoov zog. Cov flanges no feem ntau siv hauv kev lag luam uas yuav tsum tau muaj kev kub ntxhov.
6. Qhov (socket) Vuam Flange (SW):
Lub qhov (socket) vuam flanges, lossis SW flanges, yog tsim los rau cov kav dej me me thiab cov tshuab ua haujlwm siab. Lawv muaj lub qhov (socket) uas tso cai rau cov yeeb nkab ntxig, muab kev ruaj ntseg thiab ruaj khov.
7. Butt Welding Nplhaib Loose Flange (PJ/SE):
Butt welding nplhaib xoob flanges, feem ntau hu ua PJ / SE flanges, muaj ob yam sib txawv: lub flange xoob thiab lub pob tw weld caj dab stub-kawg. Hom flange no tso cai rau kev sib haum xeeb yooj yim dua thaum lub sij hawm teeb tsa, txo qhov kev pheej hmoo ntawm kev ua yuam kev.
8. Flat Vuam Nplhaib Loose Flange (PJ/RJ):
Flat welding nplhaib xoob flanges, hu ua PJ / RJ flanges, muaj qhov zoo sib xws li PJ / SE flanges, tab sis lawv tsis muaj lub caj dab. Hloov chaw, lawv tau ncaj qha welded rau cov yeeb nkab, ua kom muaj kev sib koom ua ke ruaj khov.
9. Lined Flange Npog (BL(S)):
Lined flange npog, los yog BL(S) flanges, yog tshwj xeeb flanges siv nyob rau hauv corrosive ib puag ncig. Cov flanges no tuaj nrog cov kab tiv thaiv uas tiv thaiv cov xov xwm corrosive los ntawm kev sib cuag ncaj qha nrog cov khoom flange, ncua lawv txoj sia.
10. Flange Cover (BL):
Flange npog, tsuas yog hu ua BL flanges, yog siv los kaw cov yeeb nkab kawg thaum nws tsis siv. Lawv yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj kev cuam tshuam ib ntus, muab kev tiv thaiv kev tiv thaiv ntawm cov av, khib nyiab, thiab lwm yam kab mob.
Xaus:
Hauv kev xaus, flanges yog cov khoom tseem ceeb hauv ntau qhov kev lag luam, muab kev sib txuas txhim khu kev qha ntawm cov kav dej thiab ua kom muaj txiaj ntsig thiab kev nyab xeeb ntawm cov kua dej thiab cov roj. Nkag siab txog cov yam ntxwv thiab ntau hom flanges yog qhov tseem ceeb thaum xaiv cov khoom tsim nyog rau daim ntawv thov. Txhua hom flange muaj qhov tshwj xeeb zoo raws li cov kev cai tshwj xeeb ntawm lub kaw lus. Nrog rau qhov kev paub no, engineers thiab cov tib neeg ib yam nkaus tuaj yeem ntseeg siab xaiv qhov flange rau lawv cov kev xav tau, kom ntseeg tau tias kev ua tau zoo thiab kev sib txuas mus ntev.
