Thaum twg thiaj nyiam Duplex Stainless Hlau?
Duplex Stainless Steel yog cov hlau uas muaj kev tiv thaiv corrosion zoo heev uas sib txuas cov yam ntxwv ntawm ferrite thiab austenite microstructures ntawm stainless hlau. Nov yog qee qhov xwm txheej uas cov hlau tsis muaj duplex nyiam dua:
Kev xav tau lub zog siab: Duplex stainless hlau muaj lub zog siab dua thiab hardness dua li cov austenitic lossis ferritic stainless hlau, ua rau lawv tshwj xeeb tshaj yog cov khoom siv hauv cov khoom siv uas yuav tsum tau ua haujlwm siab. Zoo Corrosion Resistance: Duplex stainless steels yog heev resistant rau kev nyuaj siab corrosion cracking thiab pitting tshwm sim los ntawm chlorides, xws li dej ntsev. Yog li ntawd, lawv yog cov zoo tagnrho rau ib puag ncig xws li marine daim ntaub ntawv, txuas hniav, docks, thiab chemical processing equipment. Structure Integrity: Vim nws lub zog siab, duplex stainless hlau tuaj yeem siv los tsim cov qauv sib dua thiab kev lag luam ntau dua thaum tswj hwm qhov kev ua tau zoo ib yam. Tus nqi-kev ua tau zoo: Qee qhov xwm txheej, txawm hais tias thawj zaug peev yuav siab dua, duplex stainless hlau tuaj yeem muab tus nqi zoo dua rau cov nyiaj hauv lub sijhawm ntev vim nws cov khoom siv zoo heev thiab ua haujlwm ntev.
Thaum tshav kub kub exchanger daim ntaub ntawv: Duplex stainless hlau yog feem ntau siv nyob rau hauv lub tshav kub exchangers vim nws siab thermal expansion coefficient thiab kub hloov lwm yam ntxwv. Sulfur-muaj ib puag ncig: Duplex stainless steels pom zoo corrosion kuj nyob rau hauv ib puag ncig uas muaj sulfides los yog sulfuric acid, xws li roj thiab roj ntau lawm. Kev lag luam ua zaub mov: Qee daim ntawv thov hauv kev lag luam khoom noj xav tau cov khoom siv uas tsis yog hlau nplaum thiab corrosion-resistant, thiab duplex stainless hlau raug xaiv rau cov khoom no.
Cov ntawv thov kub qis: Duplex stainless hlau tuav cov kev cuam tshuam zoo txawm tias qhov kub tsis tshua muaj siab, ua rau nws tsim nyog rau kev khov thiab lub tub yees. Seawater ib puag ncig: Duplex stainless hlau yog tsim rau siv nyob rau hauv marine Cheebtsam, offshore platforms thiab ntug dej hiav txwv qauv vim nws zoo heev tsis kam mus seawater corrosion.
Ib puag ncig yuav tsum tau: Duplex stainless hlau tuaj yeem txo kev siv molybdenum thiab npib tsib xee, uas pab ua kom tau raws li qee qhov kev tiv thaiv ib puag ncig.
