B7 thiab B7m yuav tsum yog cua sov kho los ntawm quenching hauv cov kua nruab nrab thiab tempering. Rau b7m fasteners, kev kho cua sov kawg, uas yuav ua rau lub tempering ua haujlwm yog tias ua tiav tom qab txhua tus machining thiab tsim cov dolling thiab ib hom kev txiav.
Qib B7 yog cov cua sov-kho cov chromium-molybdenum tsawg-alloy steel nrog tsawg kawg nkaus tensile muaj zog
Thaum txuas cov ntu no, tso gasket nyob hauv nruab nrab ntawm ob flanges, ces zawm cov flange screws, yog li ob yuav txuas ua ke kom nruj.
Lwm yam tshaj li cov roj carbon, cov no muaj nyob hauv cov npib tsib xee, manganese, chromium, silom, vanadium, molybdenum.
ASTM A320 L7 Wash cov neeg ua haujlwm tau tshwj xeeb ua rau muaj kev ua tau zoo kub. Cov fasteners feem ntau siv rau li qub, flanges, fittings, thiab cov hlab ntsha siab.
Thaum tsiv cov xov hluav taws xob siab los yog corrosive media los ntawm chrome alloy yeeb nkab los ntawm ib tus txheej txheem rau ib tug txheej txheem rau ib qho kev sib tw tom ntej, cov flanges muaj peev xwm tseem ceeb heev yog qhov tseem ceeb
ASTM Cov Specifications Pom zoo qhov tsawg kawg nkaus kev cuam tshuam tus nqi rau ASTM A320 L7 Stud Stud Bolts mus rau 20-FT-LBF @ -150F. Lub Charpy Kev Ntsuam Xyuas Kev txiav txim siab txog tag nrho cov nyiaj uas nqus tau cov khoom siv thaum lub sij hawm pob txha lov, yog li qhia cov khoom siv hluav taws xob.
Lub ASTM A320 qib l7 specification npog cov khoom stainless hlau stainless bolting rau kev pab kub tsawg. Cov txheej txheem no npog, forged, lossis hom tawv tawv tawv, bolts, screws, studges, thiab cov chaw tawm, flittings, thiab fittings.
Cov alloy F5 Flange yog siv rau kev hloov chaw ua kua thiab lwm yam dej rau ntau kev lag luam. Peb yog tsim los ntawm pab pawg ntawm tus kws tshaj lij Nim cov ntiv tes siv cov khoom siv raw zoo, cov cuab yeej niaj hnub no thiab ua ntej thev naus laus zis.
Nws yog cov qauv tshuaj lom neeg cov tshuaj lom neeg cov tshuaj lom neeg, cov khoom siv ua haujlwm, tsim nyog rau kev siv hluav taws xob, tsim nyog rau kev siv hluav taws xob, cov khoom siv roj av, flanges thiab fittings. ASTM A193 txhais ob qho tib si si (metric) thiab nti-phaus units.
Lawv yog qhov zoo tshaj plaws rau cov ntawv thov nqa cov corrosive lossis cov pa roj lossis roj cua sov. Kev lag luam uas yuav tau txais txiaj ntsig los ntawm Chrome Moly Flanges muaj xws li: Roj thiab roj thiab roj av, ua kom muaj tshuaj lom neeg.
Alloy Steel Flanges muaj cov oxidation oxidation kev ntxhov siab corrosion thiab crevice corrosion tsis kam.
A182 alloy flange muaj qhov tseeb ditensional zoo.
Cov no tseem ntxiv nrog cov me nyuam yaus xws li Sulfur, sioson, manghologon thiab phosphorous uas pab nyob rau hauv kev nce qib, lub zog, tshuaj lom neeg, thiab ntau dua.
ASTM A193 Qib B7 yog cov khoom siv chromium rau chromium-molybdenum alloy steel fasteners rau siv nyob rau hauv cov ntawv thov kub, siab thiab lub hom phiaj tshwj xeeb.
Nrog rau cov lus qhia kev lag luam ntawm Chrome Moly Alloy los ntawm cov thawj coj ua ke nrog cov muaj ntau haiv neeg muaj peev xwm ua tau raws li lossis tshaj koj qhov kev ua haujlwm tseem ceeb \ / cog cov kev qhia tshwj xeeb \ / cog cov specifications.
ASTM A182 F5 F11 F11 F11 F1 F91 Yuav tsum txias rau ib qho kub tshwj xeeb ua ntej kev kho mob kom sov
Lub Flange Txuas hom feem ntau yog los nrog ob chav nyob, nrog gasket thiab qee qhov bolts & ceev txuas sib txuas. (Cov kav dej ua ntej yog welded ntawm cov flanges, tom qab ntawd li qub thiab lwm yam khoom siv tuaj yeem ntsia tau ntawm cov flanges.)
Peb yog cov neeg xa khoom tshwj xeeb ntawm cov neeg muab khoom siv thiab tus nqi pabcuam ua haujlwm tau muab cov kev pabcuam zoo tshaj plaws rau cov txiaj ntsig zoo chrome moly flanges raws sij hawm thiab ntawm tus nqi sib tw.
Cov no muaj nyob rau hauv ntau hom xws li plam ntawm flanges.
Nyob rau hauv rooj plaub kev saib xyuas pipeline, peb tuaj yeem tshem tawm cov screws rau ntawm flange, nqa tawm cov kav dej sib raug lossis cov li qub. Lub caij no los hloov cov kav dej tshiab thiab li qub.
ASTM A193 Qib B7 Cov Kev Siv Cov Ntawv Qhia Tshwj Xeeb Cov kev cai kom muaj rau cov khoom siv kub siab lossis cov kev thov tshwj xeeb.
Alloy A182 Flange kuj muaj cov kav ntev thiab ntev.
