ASME B16.47 Series B 26-48" RF FF RTJ Duplex 2205 Duplex Stainless Hlau Flanges

Dab tsi yog qhov txawv ntawm ASME B16.5, ASME B16.47 Series A, Series B thiab API 605 Flanges?

ASME B16.5 tus qauv npog Steel Yeeb Nkab Flanges thiab Flanged Fittings los ntawm NPS 1/2 txog NPS 24 Metric/Inch hauv chav kawm siab 150 mus rau chav kawm 2500. Nws suav nrog kev ntsuas kub-kub, cov khoom siv, qhov ntev, qhov siab ntev, cim, ntsuas, thiab cov txheej txheem ntawm kev tsim qhov qhib rau cov yeeb nkab flanges thiab flanged fittings. Ob lub flanges tseem ceeb xws li vuam caj dab flange thiab qhov muag tsis pom flanges feem ntau siv hauv cov kav dej. Lo lus "B16.5" los yog "B16 5" yog siv interchangeability thiab hais txog tib tus qauv. Txawm li cas los xij, tus qauv ASME B16 5 (ANSI B16 5) tsuas yog npog loj txog 24 ntiv tes. Rau qhov ntau thiab tsawg, ASME B16.47 tus qauv npog qhov ntsuas kub-kub, cov khoom siv, qhov ntev, qhov ntev, kev ua siab ntev, kos npe, thiab kuaj cov yeeb nkab flanges hauv qhov ntau thiab tsawg NPS 26 txog NPS 60 thiab hauv kev ntaus nqi Chav Kawm 75, 150, 300, 400, 600, thiab 900.

1. ASME B16.47 Series A thiab Series B Flanges Kev Taw Qhia

ASME B16.47 (Large Diameter Steel Flanges) yog tus qauv rau txoj kab uas hla loj steel flanges loj los ntawm NPS 26 txog NPS 60. Qhov tseeb version muab qhov ntev thiab kev ntsuam xyuas hauv ob qho tib si metric thiab nti. ASME B16.47 inherently koom nrog MSS SP-44: Hlau Pipeline Flanges thiab API 605: Loj Diameter Carbon Steel Flanges. Yog li, MSS SP-44 flanges raug xaiv raws li ASME B16.47 Series A flanges, thaum API 605 flanges raug xaiv los ua ASME B16.47 Series B flanges hauv tus qauv no. Cov ntaub ntawv hauv cov qauv no yog raws li nyob rau hauv ASME B16.5 tshwj tsis yog rau cov nickel alloys uas txhais tau hais tias lawv qhia tib lub siab-kub daim ntawv rau kev xaiv cov khoom flange.

3.DUPLEX Steel 2205: Stainless Hlau Qib 2205 Duplex (UNS S32205)

Duplex 2205 stainless hlau (ob leeg ferritic thiab austenitic) yog siv dav hauv cov ntawv thov uas yuav tsum tau muaj kev tiv thaiv corrosion zoo thiab lub zog. Lub 2205 Duplex WNRF Flange tau dhau los ntawm ntau qhov kev hloov kho uas ua rau UNS S32205, thiab tau pom zoo rau xyoo 1996. Duplex Steel 2205 Industrial Flange muaj kev tiv thaiv corrosion ntau dua. Ntawm qhov kub siab tshaj 300 degree, lub nkig micro-cov ntsiab lus ntawm Duplex Steel 2205 RTJ Flange tau los nag, thiab ntawm qhov kub qis dua -50 degree cov micro-cov khoom raug hloov pauv mus rau ductile-rau-nkig; yog li no qib ntawm stainless hlau tsis haum rau kev siv ntawm cov kub no.

Cov khoom tseem ceeb
Properties of UNS S32205 Flanges yog kuvntioned nyob rau hauv cov lus hauv qab no hais txog cov khoom siv tiaj tus xws li cov phaj, cov ntawv thiab cov coils ntawm ASTM A240 lossis A240M. Cov no yuav tsis zoo ib yam ntawm lwm yam khoom xws li tuav thiab kav dej.

Corrosion Resistance

Qib 2205 stainless hlau nthuav tawm zoo heev corrosion kuj, ntau dua li ntawm qib 316. UNS S32205 Flange resists localized corrosion hom xws li intergranular, crevice thiab pitting. CPT ntawm no hom stainless hlau yog nyob ib ncig ntawm 35 degree. UNS S32205 Flanges yog resistant rau chloride stress corrosion cracking (SCC) ntawm qhov kub ntawm 150 degree. Qib 2205 stainless hlau yog qhov hloov tau zoo rau qib austenitic, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ua tsis tiav ntxov thiab ib puag ncig marine.

Thaum tshav kub kub Resistance

Lub siab oxidation kuj cuab yeej ntawm Qib 2205 yog marred los ntawm nws embrittlement saum 300 degree. Qhov embrittlement no tuaj yeem hloov kho los ntawm kev daws teeb meem annealing tag nrho. Qib no ua tau zoo ntawm qhov kub qis dua 300 degree.

Kev kho cua sov

Qhov kev kho cua sov zoo tshaj plaws rau qib no yog kev kho mob (annealing), nruab nrab ntawm 1020 - 1100 degree , ua raws li qhov txias txias. Qib 2205 tuaj yeem ua haujlwm nyuaj tab sis tsis tuaj yeem ua kom tawv los ntawm cov txheej txheem thermal.

Vuam

Cov txheej txheem vuam feem ntau haum rau qib no, tshwj tsis yog vuam tsis siv cov hlau, uas ua rau ntau tshaj ferrite. AS 1554.6 ua ntej tsim nyog vuam rau 2205 nrog 2209 rods los yog electrodes kom cov hlau deposited muaj txoj cai balanced duplex qauv.

Ntxiv nitrogen rau lub shielding gas kom paub meej tias txaus austenite ntxiv rau cov qauv. Cov khoom siv hluav taws xob yuav tsum tau khaws cia nyob rau theem qis, thiab kev siv cov cua sov ua ntej lossis tom qab yuav tsum zam. Lub co-efficient ntawm thermal expansion rau qib no yog tsawg; yog li qhov kev sib txawv thiab kev ntxhov siab tsawg dua li cov qib austenite.

Tshuab dhos

Lub machinability ntawm qib no yog tsawg vim nws lub zog siab. Kev txiav ceev yog yuav luag 20 feem pua qis dua li qib 304.

Fabrication

Kev tsim ntawm qib no kuj cuam tshuam los ntawm nws lub zog. Kev khoov thiab tsim cov qib no yuav tsum muaj cov khoom siv nrog lub peev xwm loj dua. Ductility ntawm qib 2205 tsawg dua austenitic qib; yog li ntawd, lub taub hau txias tsis tuaj yeem ua tau ntawm qib no. Txhawm rau ua cov haujlwm txias txias ntawm qib no, qhov nruab nrab annealing yuav tsum tau ua.
