Super Duplex S32750 Flange nrog siab tsis kam rau Crevice corrosion thiab kev nyuaj siab corrosion tawg

Cov khoom siv A182 F51 muaj cov pa roj carbon, 2% manghologes, Phosphorus, Sulfur, Chromium, chromium, 4.5% molybdenum thiab nitrogen nws.

Duplex stainless hlau muaj kev sib txuas ntawm ob ntu, ferrite thiab austenite hauv kwv yees sib npaug. Qhov no tso cai rau lawv kom tau txais txiaj ntsig los ntawm qhov zoo ntawm ob qho tib si ntawm cov hlau ua kom muaj zog, txhim kho werretability thiab kev tiv thaiv ntau dua rau ntau hom corrosion.

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.

ASTM A815 qhov kev qhia tshwj xeeb npog ob chav kawm dav dav, Werrititic, thiab Martensitic Stainless hlau fittings ntawm seamless thiab welded siv. Chav kawm WP fittings yog subdivided ua plaub subcasses: cov chav kawm WP-S, WP-WP-WP-WP-WX, thiab WP-WP Cov khoom siv rau cov fittings yuav tsum muaj kev lom zem, cov kab, daim hlau, lossis seamless lossis welded tubular khoom.

Unr unic untl-theem steel puag ncig kev tiv thaiv kab mob chloside kev tawg, muaj zog tiv taus cov dej tawg lossis cov ntsev kom nruj.

Siab chromium, molybdenum thiab nitrogen cov ntsiab lus cuam tshuam nrog pitting tsis zoo rau cov medtenatent thiab corrosive corrosive conduction, thiab tseem ceeb pitting txias rau tag nrho cov xov xwm, thiab tseem ceeb pitting txias rau saum 50¡Ãc.

Qhov kev nce ntxiv no yog dab tsi muab rau super duplex stainless hlau ntau dua corrosion cov yam ntxwv.

Qib yog tsim nyog rau cov ntawv thov hydraulic thiab ntsuas hauv cov chaw ua kom dav. Super Duplex Stainless Hlau muaj cov zoo tib yam raws li nws cov counterx counterpart. Lub ntsiab sib txawv ntawm ob qho yog tias super duplex muaj qhov ntau dua chromium thiab molybdenum cov ntsiab lus, ua rau muaj kev tiv thaiv corrosion. Nws tseem yog qhov tsim kom haum rau hydrogen sulfide, dilute txo thiab organic acids, thiab mob mentsis rau qib siab ntawm oxidizing cov kua qaub.

Duplex Stainless hlau yog Fe-Ni-Cur alloys muaj ntawm Ferritic-Austenitic Microstructure ntawm chav tsev kub. Cov hlau no feem ntau muaj cov kev sib txuas tau zoo ntawm kev ua kom muaj txiaj ntsig thiab theem ferritic. Duplex stainless hlau nthuav tawm kev muaj zog dua thiab zoo dua weldability tshaj li ferritic steel (Nilsson, 1992). Lawv muaj lub zog dua thiab cov corrosion zoo dua li usteneric stainless hlau (Atamert thiab huab tais, 1992). Lawv cov kev ua tau zoo engineering tau coj mus rau ntau cov ntawv thov nce, feem ntau yog nyob rau hauv cov chaw muaj kev sib raug zoo xws li sour roj pipelines thiab tshuaj lom neeg cov tshuaj tiv thaiv.

A789 unc unic s31803 thiab unspes ob qib ntawm ob chav stainless hlau uas tau siv dav hauv ntau cov ntawv thov. Cov txiv neej duplex s31803 Seamless kav yog paub rau lawv cov txiv neej ua hauj lwm zoo, muaj lub zog siab, thiab weldability thiab zoo weldability. A789 yog ib qho tshwj xeeb uas tau them seamless thiab welded tub ua los ntawm duplex steel stainless hlau.
