Cov kab lus no muab cov ntaub ntawv nruj, muaj cai siv rauC276 Alloy qhov muag tsis pom FlangeDimensions raws li ASME B16.5 tus qauv. Txhua qhov loj me uas nthuav tawm yog zoo ib yam rau cov khoom siv raws li B16.5; Txawm li cas los xij, cov khoom siv zoo tshaj plaws thiab kev tiv thaiv corrosion ntawm forged ASTM B564 UNS N10276 nce kev ua tau zoo tshaj qhov dav dav flanges.
Qhov tsawg kawg nkaus lub zog tawm los ntawm C276 yog 41 ksi (283 MPa) nyob rau hauv cov txheej txheem annealed, nrog cov nqi raug mus txog 50-60 ksi, ua kom muaj siab dua - qhov ntsuas kub thiab qhov tshwj xeeb tsis kam rau crevice corrosion, pitting, thiab kev ntxhov siab- corrosion cracking.
Hastelloy C276 Qhov muag tsis pom Flanges
Qhov muag tsis pom flanges, tseem hu ua blanking flanges, yog cov khoom siv uas siv los cais cov kav dej, txiav cov kab, lossis muab kev nthuav dav rau yav tom ntej. Hauv siab - kev pabcuam corrosion, qhov muag tsis pom flange dhau los ua qhov tsis muaj zog tshaj plaws yog tias tsis yog tsim los ntawm cov alloy tiag tiag.
Peb lub Hoobkas forges txhua C276 qhov muag tsis pom flange los ntawm cov ntawv pov thawj daim ntawv pov thawj, kom ntseeg tau tias cov qauv microstructure tsis muaj kev sib cais. Txhua daim ua tiav 100% kev kuaj xyuas ultrasonic, kev txheeb xyuas cov khoom zoo (PMI), thiab kuaj hydrostatic qhov xav tau. Nto tiav raws li lossis tshaj ASME B16.5 qhov yuav tsum tau muaj: tus qauv tsa ntsej muag (RF) nrog 125-250 µin Ra serrated tiav, lossis xaiv tau RTJ, lub ntsej muag tiaj tus, lossis machined rau cov neeg siv khoom kos duab.
ASME B16.5 Tus Qauv Txheej Txheem
ASME B16.5 tswj qhov ntev, kam rau ua, cov ntaub ntawv, thiab siab - ntsuas kub rau flanges NPS ½ txog NPS 24. Rau nickel alloy flanges, tus qauv siv yog ASTM B564 forging. Cov chav kawm siab muaj xws li Chav Kawm 150 mus rau Chav Kawm 2500. Tag nrho C276 qhov muag tsis pom flanges peb muab tag nrho traceable rau cua sov thiab ntau, nrog rau cov ntawv qhia txog zeb xeem (MTRs) suav nrog tshuaj ntsuam xyuas, tensile zog, thiab hardness.
Qhov tseem ceeb dimensional parameter muaj xws li:
O - Sab nraud txoj kab uas hla ntawm flange
T - Yam tsawg kawg nkaus thickness ntawm flange (tsis suav tsa lub ntsej muag)
R - Sab nraum txoj kab uas hla ntawm lub ntsej muag (1/16 hauv qhov siab tus qauv rau Chav Kawm 150-2500)
C - Bolt lub voj voog txoj kab uas hla
n - Tus naj npawb ntawm qhov bolts
d - Bolt qhov taub
Tolerances nruj: OD ± 0.06 nyob rau hauv rau NPS Tsawg dua los yog sib npaug rau 24, thickness +0.12 nyob rau hauv / –0.00 nyob rau hauv (Class 150–600), ntsia liaj qhov rooj qhov chaw ± 0.03 nyob rau hauv.
Chav Kawm 150 C276 qhov muag tsis pom Flange Dimensions (ASME B16.5)
Chav kawm 150 yog qhov dav tshaj plaws uas tau teev tseg rau qis - mus rau - nruab nrab siab tshuab. Hauv qab no yog tag nrho qhov ntev hauv nti.

C276 Qhov muag tsis pom Flange Qib Siab thiab Kub Derating
Thaum ASME B16.5 standardizes qhov ntev, nws yog ib qho tseem ceeb kom nkag siab tias C276 tso cai rau kom siab dua tuav ntawm qhov kub thiab txias piv rau cov qauv austenitic stainless hlau. Txawm li cas los xij, lub cev qhov ntev ntawm Chav Kawm 150 C276 qhov muag tsis pom flange zoo ib yam rau Chav Kawm 150 carbon steel qhov muag tsis pom flange. Qhov txawv yog nyob rau hauv lub siab - ntsuas kub.
Piv txwv li, ntawm 500℃F, Chav Kawm 150 carbon steel flange yuav muaj qhov siab tshaj plaws uas tsis yog - poob siab ua haujlwm siab li ntawm 140 psi. Hauv qhov sib piv, C276 flange ntawm tib qhov ntev tuaj yeem ua rau muaj kev kub ntxhov ntau dua vim tias cov hlau alloy lub zog muaj zog tuav ntawm qhov kub thiab txias.
Cov kws kho tsheb yuav tsum tsis txhob nce qhov flange qhov ntev tsis tsim nyog yog tias cov khoom siv qib muab qhov kev nyab xeeb uas yuav tsum tau muaj. Hloov pauv, txo qis hauv chav kawm kom txuag tau tus nqi ntawm cov khoom siv C276 kim yog qhov kev coj ua txaus ntshai uas ua txhaum kev tsim qauv kev nyab xeeb.
Manufacturing Tolerances thiab Quality Assurance
Nyob rau hauv peb lub Hoobkas, zus tau tej cov C276 dig muag flanges muaj precision forging thiab CNC machining. Qhov "rigor" nyob rau hauv peb cov txheej txheem yog los ntawm kev ua raws li nruj tolerances uas tshaj tus qauv coj mus muag yuav tsum tau.
Lub ntsej muag Finish: Lub ntsej muag lub ntsej muag ua tiav yuav tsum nyob nruab nrab ntawm 125 thiab 250 AARH los xyuas kom meej lub rooj zaum gasket. Ib qho chaw uas du heev yuav ua rau gasket slippage; ib qho uas ntxhib dhau yuav ua rau kom tawg.
Concentricity: Lub voj voog ntsia liaj qhov rooj yuav tsum concentric nrog flange OD. Eccentricity tuaj yeem ua rau qhov tsis sib xws bolts loading, ua rau muaj kev ntxhov siab corrosion tawg hauv cov bolts lossis flange hub.
Thickness kam rau ua: ASME B16.5 tso cai rau me ntsis tsis zoo siab ntev ntawm thickness, tab sis rau C276 daim ntaub ntawv, peb tuav ib tug zoo kam rau ua kom ntseeg tau tias lub siab ntsuas yuav tsis cuam tshuam los ntawm cov khoom tshem tawm thaum lub sij hawm machining.
Txhua C276 qhov muag tsis pom flange tau lees paub Cov Khoom Siv Zoo (PMI) txhawm rau txheeb xyuas cov ntsiab lus nickel, molybdenum, thiab chromium. Tsis tas li ntawd, kev txheeb xyuas qhov ntev yog ua los ntawm kev siv lub tshuab ntsuas ntsuas ntsuas ntsuas (CMM) kom ntseeg tau tias txhua lub qhov ntsia hlau thiab txoj kab uas hla sib tw ASME B16.5 daim phiaj xwm.
Los ntawm kev ua raws nraim li ASME B16.5 cov qauv qauv, peb xyuas kom meej tias cov khoom no sib txuas ua ke rau hauv cov txheej txheem uas twb muaj lawm thaum xa cov kev tiv thaiv zoo tshaj plaws ntawm Hastelloy C276.
