Cov Qauv Txheej Txheem ntawm Cov Raj

Cov yeeb nkab Asmeskas (ANSIB36.10 thiab ANSIB36.19) yog ib qho "loj sab nraud txoj kab uas hla koob", qhov loj me ntawm DN6 ~ DN2000mm.

Ua ntej, cov yeeb nkab sau npe "SCH" uas yog phab ntsa tuab.

① ANSI B36.10 tus qauv suav nrog SCH10, SCH20, SCH30, SCH40, SCH60, SCH80, SCH100, SCH120, SCH140, SCH160 kaum theem.

② ANSI B36.19 tus qauv suav nrog SCH5s, SCH10s, SCH40s, SCH80s plaub qib.

Qhov thib ob, qhov tuab ntawm phab ntsa yeeb nkab yog qhia los ntawm qhov hnyav ntawm yeeb nkab, uas faib qhov tuab ntawm phab ntsa yeeb nkab ua peb hom:

Cov yeeb nkab qhov hnyav txheem, qhia los ntawm STD;

Cov yeeb nkab tuab, qhia los ntawm XS;

Lub raj tuab heev, qhia los ntawm XXS.

Qib Hlau

Cov qauv thiab cov qauv

Muaj ob lub tshuab tseem ceeb ntawm cov qauv flange thoob ntiaj teb, uas yog, lub tshuab flange European uas sawv cev los ntawm German DIN (suav nrog lub tebchaws Soviet yav dhau los) thiab lub tshuab flange American uas sawv cev los ntawm American ANSI pipe flange. Tsis tas li ntawd, muaj lub flange Japanese JIS pipe, tab sis hauv cov nroj tsuag petrochemical feem ntau tsuas yog siv rau kev ua haujlwm rau pej xeem, thiab kev cuam tshuam thoob ntiaj teb me me. Tam sim no cov ntaub ntawv flange ntawm cov teb chaws hauv qab no:

1, Lub teb chaws Yelemees thiab lub teb chaws Soviet Union yav dhau los ua tus sawv cev ntawm European system yeeb nkab flange

2, tus qauv flange ntawm American system yeeb nkab, rau ANSI B16.5 thiab ANSI B 16.47

3, cov qauv flange yeeb nkab Askiv thiab Fabkis, ob lub tebchaws muaj ob pawg ntawm cov qauv flange yeeb nkab.

Hauv kev xaus, tus qauv thoob ntiaj teb ntawm cov yeeb nkab flange tuaj yeem raug sau ua ob qho sib txawv, thiab tsis tuaj yeem hloov pauv tau cov yeeb nkab flange system: lub teb chaws Yelemees ua tus sawv cev ntawm European yeeb nkab flange system; lwm qhov yog Tebchaws Meskas ua tus sawv cev ntawm American yeeb nkab flange system.

IOS7005-1 yog tus qauv uas tau muab los ntawm Lub Koom Haum Thoob Ntiaj Teb rau Kev Txheem Xyoo 1992, uas yog tus qauv flange yeeb nkab uas sib xyaw ob pawg ntawm cov yeeb nkab flanges los ntawm Tebchaws Meskas thiab Lub Tebchaws Yelemees.
