ASME B16.5 thiab ASME B16.47 yog ob qho tib si American qauv rau flanges. Txawm li cas los xij, ntau tus neeg tsis tuaj yeem paub qhov txawv ntawm ob tus qauv, yog li lawv feem ntau siv ob tus qauv tsis raug. Kab lus no yuav ua kom muaj kev sib txawv ntawm ob tus qauv.
Qhov sib txawv tseem ceeb yog qhov flange caliber ntau nrog rau cov qauv sib txawv.
ASME B16.5 suav nrog qhov ntev ntawm NPS1/2 rau NPS24 (piv txwv li 1/2 nti rau 24 nti) hauv chav kawm siab CL150-CL2500;
ASME B16.47 yog tus qauv rau qhov loj-inch flanges, suav nrog qhov ntau thiab tsawg ntawm NPS26 txog NPS60 nyob rau hauv cov chav kawm siab Class75-Class900.
ASME B16.47 tau muab faib ua ob ntu, uas yog series A thiab series B
Hais txog qhov sib txawv ntawm ob series:
ASME B16.47 Series A qhov chaw yog MSS SP-44, thiab Series B qhov chaw yog API 605.
Series A yog qhov loj ntawm flange, thiab Series B yog yeeb nkab flange
A series: loj qhov bolts, me me kom muaj nuj nqis
B series: me me qhov bolts, loj kom muaj nuj nqis
Cov kav dej loj ntawm A series thiab B series yog tib yam, tab sis qhov sib txuas loj sib txawv, uas yuav tsum tau xaiv raws li qhov xwm txheej tiag tiag.
Feem ntau, series B yog siv ntau dua hauv cov kav dej, xws li SH3406 thiab HG20615 hauv Suav teb, uas yog tag nrho los ntawm ASME B16.47 B (AP1 605). Kev xaiv tsuas yog nyob ntawm lawv tus kheej tsim kev xav tau. Yog tsis muaj kev cai tshwj xeeb, me me feem ntau xaiv. Tom qab tag nrho, tus nqi kuj tsawg.
Raws li tus qauv ntawm ASME B16.47, peb pom tias tsuas yog ob hom flanges hauv cov khoom flange siv tau rau tus qauv no:vuam caj dab flangethiabqhov muag tsis pom flange.
Nov yog qee cov duab los qhia txog ASME B16.47 tus qauv hauv kev nthuav dav. Kuv ntseeg tias koj tuaj yeem pom cov lus teb raug ntawm no.
American standard loj flange ASME B16.47 loj txoj kab uas hla yeeb nkab steel flange txheem, American txheem flange yog dav siv nyob rau hauv cov khoom txawv teb chaws los yog txawv teb chaws lag luam. Common American standard flange executive Standards: ANSIB16.5, ASME B16.47, American standard flange caliber is expressed in inches (piv txwv li 1 "1-1/2", 2 "3", ", 8", 10,12 ", 1416", 18 ", 20" 24 "28", thiab lwm yam.) Lub American standard flange siab ntsuas yog cim nrog 6 qib siab, uas yog Class 150; Chav Kawm 300; Qib 600; Chav Kawm 900; Chav Kawm 1500; Chav Kawm 2500 Asmeskas tus qauv flange yog ib feem txuas cov kav dej thiab cov kav dej, uas txuas nrog cov yeeb nkab kawg. Flange kev twb kev txuas los yog flange sib koom yog hais txog lub detachable kev twb kev txuas mechanism uas yog kev cob cog rua ntawm flange, gasket thiab ntsia liaj qhov rooj raws li ib tug pab pawg neeg ntawm sealing qauv. Lub American standard loj flange ASME B16.47 loj txoj kab uas hla yeeb nkab steel flange txheem yog tsim thiab muab los ntawm Ningbo Xinggang Pipeline Equipment Co., Ltd. flange (WNF), threaded flange NPT), American standard flange npog qhov muag tsis pom flange, Class series carbon steel thiab stainless hlau American standard flange.
