    cov khoom paub meej

    Forged steel rooj vag valve hais txog lub valve uas nws lub rooj vag txav vertically raws qhov nruab nrab ntawm txoj kab. Forged steel rooj vag li qub yog siv los txiav tawm hauv cov kav dej. Forged steel rooj vag valve yog siv dav dav, thiab feem ntau yog siv rau kev txiav cov khoom siv nrog txoj kab uas hla ntawm DN ≤ 50. Forged steel rooj vag li qub yog qhov ntau heev.

    Duplex stainless hlau yog stainless hlau nyob rau hauv uas ib nrab ntawm lub ferrite theem thiab ib nrab ntawm lub austenite theem yog tam sim no nyob rau hauv nws cov khoom quenching qauv, nrog ib tug yam tsawg kawg nkaus theem ntawm cov ntsiab lus ntawm 30%. Duplex stainless hlau yog tsim los ntawm nce Cr cov ntsiab lus los yog ntxiv lwm yam ferrite ntsiab nyob rau hauv lub hauv paus ntawm 18-8 austenitic stainless hlau. Nws tsis tsuas yog muaj ob txoj kev taw qhia ntawm austenite thiab ferrite, tab sis kuj txuag Ni alloy. Vim yog cov yam ntxwv ntawm ob-theem qauv ntawm duplex stainless hlau, los ntawm kev tswj cov tshuaj muaj pes tsawg leeg thiab cov txheej txheem kho cua sov, duplex stainless hlau tuaj yeem ua ke qhov zoo ntawm ferritic stainless hlau thiab austenitic stainless hlau. Lub xub ntiag ntawm austenite nyob rau hauv duplex stainless hlau txo qhov brittleness ntawm Cr ferrite thiab nyiam siv lead ua kev loj hlob, thaum tuav zoo heev toughness thiab vuam kev ua tau zoo; Lub xub ntiag ntawm ferrite txhim khu lub zog tawm los, tsis kam mus rau intergranular corrosion, thiab tsis kam mus rau chloride kev nyuaj siab corrosion ntawm austenite.

    Nta ntxiv

    Piv nrog rau austenitic stainless hlau, qhov zoo ntawm duplex stainless hlau yog raws li nram no:

    Ua ntej, lub zog tawm los yog ntau tshaj li ob npaug ntawm cov hlau tsis zoo austenitic, thiab nws muaj cov yas txaus thiab cov tawv tawv uas yuav tsum tau ua. Cov phab ntsa tuab ntawm kev cia lossis siab cov hlab ntsha ua los ntawm duplex stainless hlau yog txo los ntawm 30-50% piv rau austenite zoo tib yam, uas yog qhov zoo rau kev txo nqi.

    Thib ob, nws muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion tawg, txawm tias duplex stainless hlau nrog cov ntsiab lus qis tshaj plaws muaj zog tiv thaiv kev ntxhov siab ntau dua li austenitic stainless hlau, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride ions. Kev ntxhov siab corrosion yog ib qho teeb meem tseem ceeb uas zoo tib yam austenitic stainless hlau nyuaj los daws.

    Thib peb, corrosion kuj ntawm 2205 duplex stainless hlau, uas yog feem ntau siv nyob rau hauv ntau yam xov xwm, yog superior rau zoo tib yam 316L austenitic stainless hlau. Super duplex stainless hlau muaj kev tiv thaiv corrosion tsis tshua muaj siab thiab tuaj yeem hloov tau siab alloy austenitic stainless hlau lossis txawm tias corrosion-resistant alloys hauv qee qhov xov xwm.

    Plaub, nws muaj kev tiv thaiv zoo rau hauv zos corrosion. Piv nrog austenitic stainless hlau nrog cov ntsiab lus kub zoo sib xws, duplex stainless hlau tau zoo hnav tsis kam thiab qaug zog corrosion dua li austenitic stainless hlau.

    Thib tsib, cov coefficient ntawm linear expansion yog qis dua li ntawm austenitic stainless hlau, zoo ib yam li carbon steel, haum rau kev sib txuas nrog carbon steel, thiab muaj qhov tseem ceeb engineering tseem ceeb, xws li ua cov phaj sib xyaw lossis hauv ob sab phlu.

    Thib rau, tsis hais seb puas nyob rau hauv cov xwm txheej zoo li qub lossis zoo li qub, duplex stainless hlau muaj lub zog nqus ntau dua li austenitic stainless hlau, uas muaj cov txiaj ntsig zoo rau cov khoom siv los tiv thaiv cov xwm txheej npaj txhij txog xws li kev sib tsoo thiab tawg.
