Stainless hlau luj tshib
Cov txheej txheem thoob ntiaj teb cov yeeb nkab flange feem ntau muaj ob lub tshuab, uas yog European yeeb nkab flange system sawv cev los ntawm German DIN (xws li qub Soviet Union) thiab American yeeb nkab flange system sawv cev los ntawm American ANSI yeeb nkab flanges. Tsis tas li ntawd, muaj Japanese JIS yeeb nkab flanges, tab sis lawv feem ntau tsuas yog siv rau pej xeem ua haujlwm hauv cov nroj tsuag petrochemical, thiab lawv muaj kev cuam tshuam me ntsis thoob ntiaj teb. Tam sim no cov kev taw qhia ntawm cov yeeb nkab flanges nyob rau hauv ntau lub teb chaws yog raws li nram no:
1. European system yeeb nkab flanges sawv cev los ntawm lub teb chaws Yelemees thiab qub Soviet Union
2. American system yeeb nkab flange qauv, sawv cev los ntawm ANSI B16.5 thiab ANSI B 16.47
3. British thiab Fabkis cov yeeb nkab flange qauv, txhua lub teb chaws muaj ob lub flange qauv.
Hauv cov ntsiab lus, cov txheej txheem thoob ntiaj teb thoob ntiaj teb cov yeeb nkab flange tuaj yeem ua tiav raws li ob qhov sib txawv thiab tsis hloov pauv cov yeeb nkab flange: ib qho yog European yeeb nkab flange system sawv cev los ntawm lub teb chaws Yelemees; lwm qhov yog sawv cev los ntawm Teb Chaws Asmeskas American yeeb nkab flange system.
IOS7005-1 yog tus qauv tshaj tawm los ntawm Lub Koom Haum Thoob Ntiaj Teb rau Standardization hauv xyoo 1992. Cov qauv no yog qhov tseeb cov yeeb nkab flange tus qauv uas sib txuas ob lub yeeb nkab flanges los ntawm Tebchaws Meskas thiab Lub Tebchaws Yelemees.
