Tube Series Standards

US yeeb nkab series (ANSIB36.10 thiab ANSIB36.19) yog ib qho "loj sab nraud txoj kab uas hla", qhov nominal loj ntau ntawm DN6 ~ DN2000mm.

Ua ntej, cov yeeb nkab labeling "SCH" tias phab ntsa thickness.

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

Cov qauv thiab cov qauv

Muaj ob lub hauv paus tseem ceeb ntawm cov qauv thoob ntiaj teb flange, 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 Japanese JIS yeeb nkab flange, tab sis nyob rau hauv petrochemical cog feem ntau tsuas yog siv rau pej xeem ua hauj lwm, thiab nyob rau hauv lub thoob ntiaj teb lub hwj chim yog me me.Tam sim no lub teb chaws yeeb nkab flange profile hauv qab no:

1, Lub teb chaws Yelemees thiab qub Soviet Union ua tus sawv cev ntawm European system yeeb nkab flange

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

3, British thiab Fabkis cov yeeb nkab flange qauv, ob lub teb chaws muaj ob txheej txheej yeeb nkab flange qauv.

Hauv cov ntsiab lus, cov txheej txheem thoob ntiaj teb cov yeeb nkab flange tuaj yeem muab sau ua ob qhov sib txawv, thiab tsis tuaj yeem hloov pauv 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 Asmeskas cov yeeb nkab flange system.

IOS7005-1 yog tus qauv tsim los ntawm International Organization for Standardization nyob rau hauv 1992, uas yog tiag tiag ib tug yeeb nkab flange txheem uas combines ob txheej ntawm cov yeeb nkab flanges los ntawm lub tebchaws United States thiab lub teb chaws Yelemees.
