Cov kav hlau stainless hlau yog cov khoom siv hlau hauv kev lag luam, kev siv khoom, thiab kev nrhiav chaw nyob tom qab rau lawv txoj kev txhim kho corrosion, lub zog, thiab loog. Txawm li cas los xij, sib txawv ntawm cov kav hlau stainless nthuav dav qhov sib txawv sib txawv hauv kev sib xyaw, kev ua tau zoo, thiab kev nkag siab, kev nkag siab cov kev sib txawv no.
Based on material classification, stainless steel pipes are primarily categorized into three main types: austenitic, ferritic, and martensitic. Anustenitic Stainless hlau kav (xws li 304 thiab 316 series) muaj cov roj chromium siab thiab npib tsib xee, muab cov kev tiv thaiv corrosion zoo thiab tawv. Lawv tsis yog - sib nqus thiab yog qhov tsim sib nqus thiab tsim nyog rau kev siv khoom noj khoom haus, tshuaj lom neeg cov khoom siv tshuaj kom zoo nkauj. Ferritic pipes steeles (xws li 430 Series) muaj cov chromium thiab qis qis cov ntsiab lus, ua rau muaj kev tiv thaiv me ntsis tsis kam. Txawm li cas los xij, lawv muab tus nqi qis thiab kev muaj nuj nqis qis, ua rau lawv siv nyob rau hauv cov ntawv siv xws li cov vaj loog thiab khoom siv. Martensitic Stainless hlau kav (xws li 410 thiab 420 koob) muaj cov ntsiab lus carbon ntau thiab tuaj yeem ua tiav kev nyuaj siab tom qab kev kho cua sov. Lawv tsim nyog rau cov ntawv thov uas xav tau lub zog siab thiab coj kev tiv thaiv, xws li txiav cov cuab yeej thiab kabmob.
Raws li kev tsim cov txheej txheem tsim qauv, stainless hlau kav tuaj yeem raug categorized rau hauv qab thiab welded kav. Seamless kav yog tsim los ntawm cov txheej txheem zoo nkauj lossis cov txheej txheem tsis muaj, tsis muaj cov ntaub ntawv sab hauv thiab muab ntau dua kev ua kom muaj zog tshaj. Lawv haum rau siab - kev thauj cov kua thiab tshuab cov txheej txheem sib xyaw ua ke. Welded kav, ntawm qhov tod tes, yog tsim los ntawm crimping thiab vuam sheet hlau. Lawv muaj tus nqi ntau dua -} Siv tau cov kua zoo thiab siv cov khoom siv dav dav.
Kev kho deg kuj cuam tshuam cov kev ua tau zoo thiab cov tsos ntawm cov kav hlau stainless hlau. Muaj cov ua tiav suav nrog polishing, txhuam hniav, thiab sandblasting. Polished kav dej muab qhov kaj kom tiav haum rau cov ntawv thov hniav; Brushed kav muaj cov ntaub ntawv zoo nkauj, sib txuas ua ke rau kev ua kom zoo nkauj nrog cov ntaub so ntswg tsis kam; thiab cov kav dej xuab zeb muaj cov hnav ua kom zoo dua qub, ua rau lawv haum rau kev sab nraum zoov lossis chaw muaj kev nyab xeeb.
Hauv cov ntsiab lus, cov kav hlau stainless hlau sib txawv hauv ntau yam, suav nrog cov khoom siv, cov txheej txheem, thiab kev kho kom nto. Cov neeg siv yuav tsum xaiv cov khoom siv tau raws lawv cov kev thov ua kom muaj zog, thiab nyiaj txiag los xyuas kom meej ob qho tib si kom ua kom pom tseeb thiab tus nqi- ua hauj lwm zoo.
