Rau ASME B16.5 Threaded Flanges, qhov ntev tuaj yeem sib txawv raws li cov yeeb nkab nominal loj (NPS) thiab chav kawm siab. Nov yog qhov kwv yees qhov ntev rau Chav Kawm 2500 Threaded Flanges hauv nti:
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 10.75 ntiv tes, thaum OD ntawm 24-inch flange yog nyob ib ncig ntawm 53.50 ntiv tes.
Bolt Circle Diameter (BCD):Qhov loj me no nce nrog qhov loj ntawm flange. Piv txwv li, BCD ntawm 1/2-inch flange yog kwv yees li 9.50 ntiv tes, thaum BCD ntawm 24-inch flange yog nyob ib ncig ntawm 49.50 ntiv tes.
Number of Bolt Qhov:Tus naj npawb ntawm lub qhov ntsia hlau sib txawv nyob ntawm NPS. Cov qhov me me tuaj yeem muaj qhov bolts tsawg dua (piv txwv li, 4), thaum qhov loj dua tuaj yeem muaj ntau dua (piv txwv li, 20).
Bolt Qhov Diameter:Txoj kab uas hla ntawm lub qhov ntsia hlau sib txawv nrog NPS. Piv txwv li, lub qhov taub qhov taub rau 1/2-inch flange yog kwv yees li 1.13 ntiv tes.
Hub Diameter:Txoj kab uas hla ntawm lub ntsej muag tsa ntawm lub hauv paus ntawm flange nce nrog qhov loj ntawm flange.
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 qhov ntev tshwj xeeb yuav txawv raws li cov chaw tsim khoom thiab cov qauv ua raws. Rau qhov tseeb thiab cov ncauj lus kom ntxaws, nws raug nquahu kom xa mus rau ASME B16.5 tus qauv lossis sab laj cov chaw tsim khoom tshwj xeeb rau qhov tshwj xeeb flange loj thiab chav kawm.
