Nco tseg: Cov luj no yog qhov tseem ceeb theoretical thiab tej zaum yuav txawv me ntsis nyob ntawm kev tsim khoom, tig hom (RF / FF / RTJ), thiab cov kev coj ua tshwj xeeb.
316H Flange QhovStandards thiab Pressure Classes
Flange luj tsis yog arbitrary; lawv tau hais los ntawm cov qauv thoob ntiaj teb, feem ntau ASME B16.5 (rau NPS ½ "mus rau 24") thiab ASME B16.47 (rau cov kab loj dua). Qhov hnyav ntawm 316H flange feem ntau yog tsav los ntawm ob qhov sib txawv: Nominal Pipe Size (NPS) thiab Qib Siab.
Cov chav kawm siab feem ntau suav nrog 150, 300, 600, 900, 1500, thiab 2500. Raws li cov chav kawm siab nce, lub flange thickness thiab hub txoj kab uas hla nce kom muaj kev siab dua sab hauv, ua rau tsis muaj - linear nce hauv qhov hnyav. Piv txwv li, Chav Kawm 600 flange hnyav dua li ob npaug ntawm Chav Kawm 150 flange ntawm tib txoj kab uas hla vim qhov nce ntxiv ntawm cov khoom ntim uas xav tau rau kev nyab xeeb margins.
Tsis tas li ntawd, hom flange cuam tshuam loj. Ib qho Weld Neck flange feem ntau hnyav dua li Slip-Ntawm flange ntawm tib chav kawm vim qhov txuas txuas thiab caj dab geometry. Hloov pauv, qhov muag tsis pom flange, tsis muaj bore, yuav muaj qhov loj tshaj plaws rau NPS thiab chav kawm.
316H Flange QhovNtsuas qhov hnyav
Rau lub hom phiaj engineering, kev cia siab ib leeg ntawm cov kab kos tuaj yeem muaj kev pheej hmoo yog tias qhov kev cai loj lossis tsis yog - tus qauv kam rau ua koom nrog. Raws li cov chaw tsim khoom, peb pom zoo kom txheeb xyuas qhov hnyav uas siv cov qauv ntawm qhov ntom ntom. Qhov no ua kom nruj rau koj qhov kev yuav khoom tshwj xeeb.
Qhov hnyav theoretical (WW) yog xam raws li:
W=V×ρW=V×ρ
Qhov twg:
VV=Volume ntawm flange (in³ lossis cm³)
ρρ=Qhov ceev ntawm 316H Stainless Hlau (0.289 lb/in³ lossis 8.0 g/cm³)
Kev xam qhov ntim ntawm cov duab kos duab zoo li Weld Neck flange yuav tsum tau rhuav tshem cov khoom ua kom yooj yim geometric duab: lub nplhaib, hub, thiab lub caj dab. Txawm li cas los xij, rau kev kwv yees yooj yim ntawm Slip-On lossis Plate flange, cov qauv hauv qab no feem ntau siv hauv kev lag luam:
W=π 4 × (OD2−ID2) × T × ρW=4π × (OD2−ID2) × T × ρ
Qhov twg:
OD=Sab nraud ntawm lub flange
ID=Inner Diameter (Bore)
T=Thickness ntawm flange
ρ= Qhov ceev tsis tu ncua
Piv txwv xam: Xav txog 6-inch NPS Chav Kawm 150 Slip-On Flange.
OD=11.00 ntiv tes
ID=6.62 ntiv tes (kwv yees bore)
Thickness=0.88 ntiv tes
Qhov ceev=0.289 lb/in³
Volume≈0.7854 ×(121−43.8) × 0.88≈53.3 in3Volume≈0.7854 ×(121−43.8) × 0.88≈53.3 in3 Nyhav≈53.3 × 0.289≈15.4 Qhov hnyav ≈ 53.3 × 0.289≈ 15.4 lbs
Kho: Cov qauv yooj yim no suav cov nplhaib nkaus xwb. Ib qho yuav tsum ntxiv qhov hnyav ntawm lub hub thiab lub ntsej muag tsa. Hauv kev xyaum, 6 "Class 150 flange hnyav dua li ntawm 26 lbs raws li ASME lub rooj.
Tej yam cuam tshuam rau qhov tseeb vs. Theoretical Nyhav
Ob peb yam tuaj yeem ua rau muaj kev sib txawv ntawm cov ntsuas theoretical thiab qhov hnyav tsim tawm:
Manufacturing Tolerances: ASME B16.5 tso cai rau qee qhov ntev ntev uas cuam tshuam qhov hnyav kawg
Forging Practice: Cov txheej txheem forging sib txawv tuaj yeem ua rau cov khoom siv sib txawv me ntsis
Surface Finish: Machined nto tshem cov khoom, txo qhov hnyav kawg
Hom ntsej muag: tsa lub ntsej muag, lub ntsej muag tiaj tus, thiab RTJ teeb tsa muaj cov khoom sib txawv
Cov khoom sib xyaw: me ntsis kev hloov pauv hauv cov ntsiab lus alloying cuam tshuam qhov ntom ntom
Rau cov ntawv thov tseem ceeb uas xav tau cov ntaub ntawv hnyav, peb pom zoo kom tau txais qhov ntsuas qhov hnyav los ntawm cov ntawv pov thawj zeb xeem (EN 10204 Hom 3.1 lossis 3.2).
