Standard system:

Feem ntau muaj ob lub tshuab ntawm cov yeeb nkab flange hauv ntiaj teb, 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 flange. Tsis tas li ntawd, muaj JIS yeeb nkab flanges hauv Nyij Pooj, tab sis lawv feem ntau tsuas yog siv rau kev siv hluav taws xob hauv cov nroj tsuag petrochemical, thiab muaj kev cuam tshuam me ntsis thoob ntiaj teb. Cov hauv qab no yog cov lus qhia luv luv ntawm cov yeeb nkab flanges hauv ntau lub teb chaws:
1. European system yeeb nkab flanges sawv cev los ntawm lub teb chaws Yelemees thiab qub Soviet Union
2. American system yeeb nkab flange tus qauv, sawv cev los ntawm ANSI B16.5 thiab ANSI B 16.47
3. British thiab Fabkis cov yeeb nkab flange qauv, ob lub casing flange qauv rau txhua lub teb chaws.
Txhawm rau ua kom tiav, cov txheej txheem 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: European yeeb nkab flange system sawv cev los ntawm lub teb chaws Yelemees; Lwm qhov yog American yeeb nkab flange system sawv cev los ntawm Tebchaws Meskas.

Kev faib tawm

1. Kev faib tawm los ntawm cov khoom siv:
Carbon hlau: ASTM / ASME A234 WPB, WPC
Stainless hlau: ASTM / ASME A403 WP 304-304L-304H-304LN-304N
ASTM / ASME A403 WP 316-316L-316H-316LN-316N-316Ti
ASTM / ASME A403 WP 321-321H ASTM / ASME A403 WP 347-347H
2. Raws li txoj kev tsim khoom, nws tuaj yeem muab faib ua kev thawb, nias, forging, casting, thiab lwm yam.
3. Cov qauv tsim khoom tuaj yeem muab faib ua cov qauv hauv tebchaws, cov qauv hluav taws xob, cov qauv nkoj, cov qauv tshuaj, cov qauv dej, cov qauv Asmeskas, cov qauv German, cov qauv Japanese, cov qauv Lavxias, thiab lwm yam.

Distribution yam ntxwv

(1) Lub sijhawm dabtsi yog khoov los ntawm qhov chaw siab sib txawv ntawm qhov loj thiab me kawg ntawm qhov sib txawvreducernyob rau hauv qhov kev txiav txim ntawm sab hauv siab ua rau qhov tshwm sim uas qhov kawg loj qhib kuj thiab qhov kawg me me shrinks kuj;

(2) Nyob rau hauv qhov kev txiav txim ntawm lub siab sab hauv, lub circumferential kev nyuaj siab nyob rau hauv lub puab nto ntawm lub loj kawg ntawm lub eccentric sab thiab sab nrauv ntawm nruab nrab ntawm lub eccentric sab ntawm lubeccentric reduceryog qhov loj tshaj plaws.
