British Standard BS 3293: 1960-Carbon Steel Pipe Flanges (dhau 24 nti nominal loj) rau Petroleum Kev Lag Luam, npog Chav Kawm 150lb txog 600lbweld caj dab flangesthiabplam ntawm flanges.
Cov hauv qab no yuav qhia txog qhov ntev thiab kam rau ua ntawm lubvuam caj dab flange thiab lub caj dab tiaj vuam flangeua BS3293.
BS3293 weld caj dab thiab plam ntawm flange belongs rau American standard flange standard system.Nws yog ib qho kev tshwm sim ntawm American standard flange (tseem hu ua ANSI txoj kev) thiab ib qho ntawm feem ntau siv flanges ntawm cov khoom siv lossis cov kav dej.
BS 3293: 1960 yog cov khoom siv thiab loj.Cov qauv no tsuas yog siv tau rau forged carbon steelSlip-on flange thiab welded caj dab flange ntawm nominal txoj kab uas hla26 nti thiab loj dua rau roj avMuaj drilling, bolting, xov thiab thickness
Dimensions kuj tseem siv tau rau qhov kawg.
Flanges rau valve thiab fittings.Plaub hom flanges yog muab, uas yog class150, 300, 400 thiab 600. BS 3293: 1960 tsis suav nrog: kev ntsuas siab / kub;Lub npe ntawm flange siv yog siv rau kev txheeb xyuas lub hom phiaj
Daim ntawv pov thawj: BS 1503, BS 1560, BS 1750, BS 3351, ANSI B16.20, ASTM A 105
Qhov sib txawv ntawm Weld Neck Flanges thiab Slip On Flanges
1. Cov ntaub ntawv sib txawv weld:
Kev tshuaj xyuas hluav taws xob tuaj yeem ua rau cov welds ntawm lub caj dab pob tw vuam flange, tab sis tsis yog rau lub caj dab ca vuam flange.Lub vuam daim ntawv ntawm lub caj dab taub qab-vuam flange thiab yeeb nkab yog ncig weld, thaum vuam daim ntawv ntawm tiaj vuam flange thiab yeeb nkab yog fillet weld.Butt welding yog lub pob tw ncig, thiab cov vuam tiaj tiaj yog ob lub fillet circumferential welds.Qhov sib txawv ntawm ob yog qhov sib txuas ntawm lub caj dab taub qab-vuam flange thiab lub nozzle belongs rau Class B seam, thaum lub vuam txuas lub caj dab pob tw-welding flange thiab lub nozzle belongs rau Class C seam.
2. Cov khoom sib txawv:
Cov khoom ntawm lub caj dab taub qab vuam flange feem ntau yog ua los ntawm forged steel qhov chaw los ntawm machining.Cov khoom siv ntawm plam-on vuam flange nrog lub caj dab yog ua los ntawm cov hlau zoo tib yam nrog cov thickness uas yuav tsum tau ua los ntawm kev ua haujlwm.
3. Txawv nominal pressures:
Lub nominal siab ntawm lub caj dab pob tw-welding flange yog 1-25MPa, uas yog siab dua.Lub nominal siab ntawm lub caj dab ca vuam flange yog 0.6-4MPa.Piv nrog rau lub caj dab ca vuam flange, nws qib siab yog qis dua thiab nws lub peev xwm hloov mus rau qhov siab kuj qis dua.
