Cov khoom siv S32205 DuPlex Asme asme sa182 pob tw Weld Flanges yog tsim nyog rau dej hiav txwv thiab cov khoom siv hluav taws xob tuaj yeem tiv thaiv kom sov txog 600,000Ãf, thaum tseem muaj cov yam ntxwv zoo.

Qee qhov dual-theem weld flanges muaj cov oxidation zoo tsis kam ntawm qhov kub tshaj 300 qib qis dua 300 degrees raug rau 475 degrees Celsius. Cov theem qib ob steel s32205 ntiv nplhaib sib koom ua ke kuj tseem muaj kev ua kom muaj zog thiab kev qaug zog zoo li cov khoom lag luam thermal thiab ntau dua thermal conductivity tshaj li tau lees paub.

Lub zog kub kub ntawm dual theem steel steel flanges zoo ib yam li Alloy 100 li ntawm 950 txog 1150¡Ãc. Txawm li cas los xij, lub zog tensile ntawm cov flanges nce sai sai hauv qab 900¡Ãc.

Ib Flange yog ib qho kev tawm tsam, daim di ncauj lossis sab nraud, tog twg los sab nraud lossis sab hauv, uas yog cov nqaj hlau xws li ib tug t-nqaj); Rau cov ntawv yooj yim tau yooj yim \ / hloov ntawm kev sib cuag nrog lwm yam khoom (raws li flange thaum kawg ntawm cov yeeb nkab, chav dej lub tog raj kheej, lossis ntawm lub ntsej muag lub koob yees duab); Los yog rau kev ruaj khov thiab taw qhia kev txav ntawm lub tshuab lossis nws cov ntu (raws li sab hauv flange ntawm tsheb ciav hlau lossis lub log los ntawm kev khiav tawm ntawm cov ciav hlau). Lo lus "Flange" kuj yog siv rau hom cuab yeej siv los ua cov flanges.

Lub Flange yog qhov thib ob feem ntau siv koom nrog txoj kev tom qab selding. Kev siv flanges tau siv thaum cov pob qij txha xav tau dismantling. Nws muab kev hloov tau rau kev saib xyuas. Flange txuas cov yeeb nkab nrog ntau yam khoom siv thiab li qub. Breakup Flanges tau ntxiv rau hauv cov raj xa hluav taws yog tias kev saib xyuas tsis tu ncua thaum lub sijhawm cog ntoo.

Duplex stainless tus khub qib yog lub npe denplex vim tias cov qib ob flange sib npaug muaj ob-theem microstructure. Qhov no ob-theem microstructure muaj cov ferritic thiab ustenitic stainless hlau-zoo li nplej. Raws li lub npe qhia, lub duplex kev tsim kho muab cov duplex stainless ntsaws qhov hluav taws xob muaj ntau yam khoom txaus nyiam.

Nws tseem zoo heev rau lub zog li cov khoom siv tau zoo tshaj plaws ntxiv dag zog. Nitrogen yog ib qho muaj zog Austenite yav tas los qub, thiab ntxiv rau ntawm nitrogen zoo heev txhim kho cov tawv ntawm ob theem steels. Nws kuj ncua qhov tsim ntawm intermetallic cov tebchaw txaus kom tso cai rau kev ua thiab FOORICE ntawm ob hom hlau. Nickel yog ib qho kev siv tsis huv uas txhawb kev tsim ntawm Austenitic FCC qauv, uas ua rau muaj kev sib zog ntawm ob theem steels.

 Muaj feem ntau muaj rau cov neeg nyob rau hauv plaub pawg uas yog Martensitic, Ferritic, thiab Austenic thiab lub xeem yog cov tawv tawv. Cov no yog tsim raws li lawv tau raws li cov qauv crystalline thiab stainless hlau. Lawv muab rau koj nrog lub chaw nyob ntawm kev kub siab - tseem muab rau lawv nrog lub zog ntawm unc unicfd kav dej. Lawv tau hais tias yuav tau ua los ntawm cov tshuaj lom neeg muaj pes tsawg leeg uas muaj sib npaug ntawm kev txhawb nqa thiab qib siab.

Duplex stainless hlau flanges tau dav siv nyob rau hauv cov pipeline tshuab, risers, manifolds, thiab kuj nyob rau hauv lub pethoden kev lag luam nyob rau hauv daim ntawv ntawm siab cov hlab thiab pipelines. Duplex 2205 Flange cov khoom muaj lub zog zoo thiab lub siab tsis kam rau corrosion, pitting thiab crevice corrosion. Lub nominal tshuaj muaj pes tsawg leeg ntawm duplex 2205 yog 22% chromium, 3.2% molybdenum, 5% npib tsib xee thiab lwm yam alloy thiab nitrogen.
