2. Mechanical Performance Requirements:
Cov kev xav tau muaj zog: Xaiv qhov tsim nyog duplex stainless hlau raws li cov khoom siv zog xav tau ntawm daim ntawv thov scenario. Yog hais tias nws yuav tsum tau tiv thaiv loads siab dua los yog pressures, yuav tsum tau xaiv qib high-strength.
Toughness yuav tsum tau: Qee lub sij hawm uas tej zaum yuav raug cuam tshuam los yog kev co, xws li txuas hniav, mechanical qhov chaw, thiab lwm yam, cov khoom yuav tsum muaj zoo toughness. Feem ntau hais lus, duplex stainless hlau nrog qhov sib npaug austenite-ferrite ntau dua muaj zog dua.
3. Kev ua tau zoo:
Vuam kev ua tau zoo: Yog xav tau vuam, xaiv duplex stainless hlau nrog zoo vuam kev ua tau zoo. Qee qhov duplex stainless hlau yuav muaj teeb meem xws li theem tsis txaus thiab txo qhov kev tiv thaiv corrosion nyob rau hauv tshav kub cuam tshuam tom qab vuam, yog li nws yuav tsum tau xaiv cov khoom siv vuam thiab cov txheej txheem tsim nyog.
Kev ua haujlwm txias ua haujlwm: Rau qhov chaw uas yuav tsum tau ua kom txias, xws li khoov thiab stamping ntawm cov kav dej thiab cov phaj, qhov kev ua haujlwm txias ntawm cov khoom yuav tsum raug txiav txim siab. Qee qhov duplex stainless hlau tuaj yeem ua rau muaj zog thiab txo qis hauv cov yas tom qab ua haujlwm txias, thiab kev kho cua sov yuav tsum tau ua kom rov ua haujlwm.
Txiav kev ua tau zoo: Yog tias nws cuam tshuam nrog kev siv tshuab, xws li tig, milling, thiab lwm yam, nws yog ib qho tsim nyog los xaiv cov ntaub ntawv nrog kev ua haujlwm zoo dua los txhim kho kev ua haujlwm thiab txo cov nqi ua haujlwm. Qhov kev ua tau zoo ntawm duplex stainless hlau tuaj yeem txhim kho los ntawm kev tswj cov khoom muaj pes tsawg leeg thiab hom kev suav nrog.
4. Kev khiav hauj lwm qhov kub thiab txias:
Kub kub ib puag ncig: Thaum siv nyob rau hauv qhov kub thiab txias ib puag ncig, lub siab kub lub zog, oxidation kuj thiab theem stability ntawm cov khoom yuav tsum raug xam tias yog. Qee qhov duplex stainless hlau tuaj yeem raug hloov pauv theem ntawm qhov kub thiab txias, ua rau kev ua haujlwm tsis zoo, yog li nws yuav tsum xaiv cov qib tsim nyog rau kev siv kub.
Tsis tshua muaj kub ib puag ncig: Rau duplex stainless hlau siv nyob rau hauv qhov kub thiab txias ib puag ncig, yuav tsum tau them nyiaj mloog mus rau nws tsis tshua muaj kub toughness thiab tej yam kuj. Qee qhov duplex stainless hlau tuaj yeem ua nkig ntawm qhov kub thiab txias, cuam tshuam rau nws txoj kev nyab xeeb, yog li nws yuav tsum xaiv cov khoom tsim nyog rau kev siv kub tsawg.
5. Tus nqi qis:
Tus nqi ntawm cov khoom siv: Cov nqi sib txawv ntawm duplex stainless hlau sib txawv heev, yog li koj yuav tsum xaiv cov khoom siv raws li qhov project pob nyiaj siv. Feem ntau hais lus, super duplex stainless hlau nrog lub zog siab thiab siab corrosion kuj yog kim dua.
Tus nqi ua haujlwm: Xav txog kev ua haujlwm nyuaj thiab tus nqi ntawm cov khoom siv, xaiv cov khoom siv yooj yim tuaj yeem txo tus nqi tag nrho.
6. Kev tswj hwm thiab tus qauv yuav tsum muaj:
Cov qauv kev lag luam: Xaiv duplex stainless hlau uas ua tau raws li qhov yuav tsum tau ua raws li cov qauv tsim thiab cov kev qhia tshwj xeeb ntawm kev lag luam.
Daim ntawv pov thawj uas yuav tsum tau muaj: Qee qhov kev thov tshwj xeeb yuav xav tau cov ntaub ntawv kom muaj cov ntawv pov thawj tshwj xeeb, xws li NACE daim ntawv pov thawj, thiab lwm yam. Ua kom cov hlau duplex stainless hlau tau xaiv raws li qhov yuav tsum tau muaj ntawv pov thawj.
Cov saum toj no yog txoj kev xaiv cov duplex stainless hlau uas haum rau koj. Yog tias koj xav paub ntau ntxiv txog kev txhim kho kev cia siab thiab cov yam ntxwv ntawm duplex stainless hlau, thov ua tib zoo saib rau www.jstisco.com !
