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.

Duplex Stainless hlau Stainless hlau ua ke ua ke ntawm Austenitic thiab Ferritentic tsev neeg los muab cov txiaj ntsig tsawg dua - feem ntau ntawm tus nqi qis dua lwm cov hlau alloys.

Los ntawm corrosion tsis kam rau lub zog, kev lag luam thoob ntiaj teb txaus siab rau cov khoom ntawm cov khoom ntawm 2507 Super Duplex seamless. Vim yog ob lub microstructure theem, tus weldability ntawm no alloy tau cais zoo li zoo, uas yog vim li cas rastive zoo thiab ruaj ruaj loj super duplex Welded yeeb nkab tuaj yeem ua tiav.

2507 kuj tau siv nyob rau hauv flue roj scrubbing khoom, pulp thiab ntawv zeb khoom siv, offshore roj ntau lawm \ / tshuab thiab roj thiab roj kev lag luam khoom.

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.

Cov khoom lag luam Duplex F51 puag ncig feem ntau siv nyob rau hauv cov roj thiab roj kev lag luam, cov khoom siv hluav taws xob, cov hlab ntsha, thiab lwm yam. Feem ntau ntawm cov cuab yeej ua haujlwm siv inglex 2205. Nws tseem siv los ntawm kev cia thiab kev thauj mus los ntawm kev lag luam.

Corrosion Kuj: raws li nrog txhua tus stainless hlau, corrosion tsis yog nyob ntawm cov muaj pes tsawg ntawm cov khoom siv roj stainless, nrog chromium, molybdenum thiab nitrogen cov ntsiab lus yog qhov tseem ceeb tshaj plaws. Duplex stainless hlau yog heev corrosion resistant thiab txawm nyob hauv chloride thiab sulphide ib puag ncig kev ua kom muaj kev ntxhov siab corrosion (SCC). SCC yog hom corrosion uas tshwm sim thaum ib qho kev teeb tsa tshwj xeeb tam sim no: tensile kev nyuaj siab, ib puag ncig corrosive thiab qhov kub txaus.

Lub 2205 gasket yog hu ua lub duplex stainless hlau gaset vim nws muaj kev sib xyaw ua ke thiab tuaj yeem ua rau hauv freedeners vim nws cov siab corrosion. Nws tau muaj ntau dua corrosion tsis kam tshaj 316 stainless hlau thiab kuj tseem tiv taus kev ntxhov siab thiab chloride tawg. 2205 tau txiav txim siab ua tau zoo vim nws tsuas yog 5% npib tsib xee thiab yog tsis tshua kim dua hastelloy c276 fasteners.

Ob qho tib si Asme B16.5 thiab ASME B16.47 tau pom zoo cov yeeb nkab flanges ua los ntawm ib qho ntawm ob lub stuplex ntau.
