DIN EN 1092-1 yog dab tsi?
DIN EN 1092-1 yog tus qauv European uas qhia txog qhov yuav tsum tau muaj rau cov flanges ncig rau cov kav dej, li qub, fittings, thiab accessories. Nws yog lub npe "Flanges thiab lawv cov pob qij txha - Lub voj voog flanges rau cov kav dej, li qub, fittings thiab accessories, PN xaiv - Ntu 1: Hlau flanges."
Cov txheej txheem no txhais tau ntau hom flanges, xws li lub caj dab weld, plam-on, threaded, thiab dig muag flanges, thiab lawv qhov ntev, cov ntaub ntawv, thiab kev ntsuas siab. Nws muab cov lus qhia rau kev tsim, qhov ntev, thiab kos npe ntawm flanges siv hauv cov kav dej thoob plaws teb chaws Europe.
Lub npe "PN" nyob rau hauv lub npe yog hais txog lub siab ntsuas ntawm lub flanges, uas sawv cev rau "Pressure Nominal." DIN EN 1092-1 tsim kom muaj kev sib koom ua ke rau kev qhia cov flanges hauv European Union, txhawb kev sib xws thiab kev sib koom tes hauv kev tsim thiab kev teeb tsa ntawm cov kav dej.

DIN EN 1092-1 vs. Yav dhau los DIN Norm: Nkag siab qhov txawv ntawm Flange Standards
Flange Hom thiab Markings:
Yav dhau los DIN Norm: Flanges tau muab cais siv DIN cov qauv xws li DIN 2635 thiab DIN 2633, txhua tus muaj nws tus kheej hom thiab cim qhov system.
DIN EN 1092-1: Txais yuav ib qho kev sib koom ua ke uas flange hom raug xaiv nrog cov lej, xws li Hom 11 rau vuam caj dab flanges thiab Hom 05 rau qhov muag tsis pom flanges.
Kev ntsuas siab:
Yav dhau los DIN Norm: Flanges tau tsim raws li qhov kev ntsuas siab xws li PN6 thiab PN40.
DIN EN 1092-1: Siv qhov zoo sib xws nominal siab (PN) system tab sis standardizes nws thoob plaws teb chaws Europe, kom ntseeg tau tias sib xws nyob rau hauv lub siab ratings rau flanges.
Qhov loj thiab cov khoom sib xws:
Yav dhau los DIN Norm: Qee qhov flange qhov ntau thiab tsawg los ntawm cov qauv DIN yav dhau los tseem yuav siv nrog DIN EN 1092-1 qhov ntau thiab tsawg.
DIN EN 1092-1: Qhia qhov loj me flange tshiab uas tej zaum yuav tsis muaj nyob rau hauv cov qauv DIN dhau los, muab ntau yam kev xaiv rau cov neeg siv.
Lub Sijhawm Hloov Pauv thiab Coexistence:
Lub Sijhawm Hloov Pauv: Txawm hais tias qee cov qauv DIN flange tau hloov pauv los ntawm DIN EN 1092-1, lwm tus tseem nyob nrog vim muaj kev sib tw ntawm kev hloov cov qauv khoom siv ntev.
Kev sib koom ua ke: Flanges tuaj yeem ua raws li cov qauv DIN qub, DIN EN 1092-1 tus qauv tshiab, lossis ob qho tib si, nyob ntawm cov chaw tsim khoom thiab cov kev cai hauv cheeb tsam.
