Rau Chav Kawm 900 Lap Joint Flange raws li ASME B16.5 tus qauv, ntawm no yog qhov kwv yees qhov ntev hauv nti rau ntau qhov ntau thiab tsawg:
Nominal Pipe Size (NPS):Ntau yam ntawm 1/2 nti (DN 15) txog 24 nti (DN 600) thiab loj dua.
Sab nraud txoj kab uas hla (OD):OD sib txawv nrog NPS. Piv txwv li, OD ntawm 1/2-inch flange yog kwv yees li 8.50 ntiv tes, thaum OD ntawm 24-inch flange yog nyob ib ncig ntawm 49.50 ntiv tes.
Txoj kab uas hla (BD):Lub bore txoj kab uas hla ntawm ib tug ncej puab flange phim lub sab hauv txoj kab uas hla (ID) ntawm cov yeeb nkab uas nws txuas. Nws feem ntau yog tib yam li cov yeeb nkab nominal (NPS).
Thickness (T):Lub thickness ntawm lub puab tsaig flange yog sib xws thiab feem ntau sib haum mus rau lub thickness ntawm cov yeeb nkab nws yog siv nrog.
Hub Diameter (HD):Lub hub txoj kab uas hla ntawm ib tug ncej puab flange yog feem ntau loj dua OD kom yooj yim haum rau cov yeeb nkab.
Zuag qhia tag nrho Length los ntawm Hub (LTH):Qhov loj me no, uas yog qhov kev ncua deb ntawm lub ntsej muag ntawm flange mus rau qhov kawg ntawm lub hub, kuj nce nrog qhov loj ntawm flange.
Flange Thickness:Lub thickness ntawm flange sib txawv raws li cov chav kawm siab.
Cov qhov ntev no yog kwv yees thiab yuav txawv me ntsis nyob ntawm cov chaw tsim khoom thiab cov kev xav tau tshwj xeeb. Nws yog ib qho tseem ceeb uas yuav tau tham txog ASME B16.5 tus qauv lossis cov chaw tsim khoom tshwj xeeb rau qhov tseeb qhov ntev rau ib qho kev sib koom tes flange loj.
