Taw qhia rau kev siv ntawmflange kev paub
Cov yeeb nkab flangesthiab lawv cov gaskets thiab fasteners yog collectively hu uaflangepob qij txha. Flange sib koom ua ke yog dav siv hauv engineering tsim, nrog rau ntau yam ntawm cov khoom. Nws yog ib qho tseem ceeb ntawm kev tsim cov kav dej, cov yeeb nkab haum valve, thiab tseem yog ib qho tseem ceeb ntawm cov khoom siv, cov khoom siv (xws li manhole, iav qib ntsuas, thiab lwm yam).
Tsis tas li ntawd, lwm cov kws tshaj lij xws li kev lag luam rauv, thermal engineering, dej thiab dej ntws, cua sov thiab qhov cua, kev tswj tsis siv neeg, thiab lwm yam, kuj feem ntau siv flange pob qij txha. Cov khoom siv raw: forged steel, WCB carbon steel, stainless hlau, 316L, 316, 304L, 304, 321, chromium molybdenum steel, chromium molybdenum vanadium steel, molybdenum titanium, hauv ob sab phlu roj hmab, hauv ob sab phlu fluorine raw khoom.
Hom:tiaj welding flange, caj dab flange, taub qab vuam flange, nplhaib kev twb kev txuas flange, qhov (socket) flange, thiab qhov muag tsis pom phaj, thiab lwm yam. Cov kev ua tau zoo yog GB series (tus qauv hauv tebchaws), JB series (chaw kho tshuab), HG series (Chemical Department), ASME B16.5 (American standard), BS4504 (British standard), DIN (German) standard), JIS (Japanese standard).
ntiaj teb lub cevflangespecification system: Muaj ob lub ntsiab yeeb nkab flange specification systems nyob rau hauv lub ntiaj teb no, uas yog cov European yeeb nkab flange system sawv cev los ntawm German DIN (xws li lub qub Soviet Union) thiab American yeeb flange system sawv cev los ntawm American ANSI yeeb flange. Tsis tas li ntawd, muaj Japanese JIS yeeb nkab flanges, tab sis nyob rau hauv cov khoom siv petrochemical feem ntau tsuas yog siv rau pej xeem kev ua haujlwm, thiab qhov cuam tshuam hauv ntiaj teb yog me me.
