Cov pa roj carbon steel flanges tau dav siv hauv kev teeb tsa cov kav dej ua haujlwm. q235a uaA105 yog ob hom carbon steel cov ntaub ntawv uas feem ntau siv. Txawm li cas los xij, lawv cov lus hais txawv, qee zaum txawv heev. Yog li ntawd qhov txawv ntawm lawv yog dab tsi? Qhov txawv ntawm lawv cov nqi yog dab tsi?
Ua ntej tshaj plaws, Q235 carbon steel flange yog ib qho flange ntau heev xaiv los ntawm ntau tus neeg yuav khoom vim nws tus nqi qis.q235 ua Feem ntau siv qhov kub ntawm -10 ~ 350 ℃. Tsis tas li ntawd, Q235 feem ntau yuav tsum tau tsim lub siab tsawg dua 3.0MPa. Hais txog kev siv,
Q235 carbon steel flange feem ntau yog siv los ntawm cov kav dej uas tsis muaj tshuaj lom thiab tsis yog-combustible pipeline nruab nrab, thiab ntawm chav kawm, nws kuj yog siv rau cov qauv hlau, xws li kev txhawb nqa thiab hangers, thiab lwm yam., tab sis Q235 yuav tsum tsis txhob siv rau liquefied hydrocarbon, thiab. qib ntawm toxicity yog heev thiab tsis tshua muaj teeb meem nruab nrab.
Carbon steel flange yog ua los ntawm cov khoom siv Q235. Nco ntsoov tias qhov no txhais tau tias forging Q235, vim tias cov phaj tuab Q235 tuaj yeem siv ncaj qha los ua flange, tab sis nws qhov kev ua tau zoo yog qis dua li ntawm forging. Nws yog tsuas yog vim qhov sib txawv ntawm cov qauv siv lead ua sab hauv, uas yog qhov nyuaj rau kev paub qhov txawv ntawm qhov muaj pes tsawg leeg thiab kev ua tau zoo. Lub hauv paus chiv keeb ntawm Q235 yog vim tias lub zog tawm los yog siab dua 235, qhov ntsuas lub zog ntawm cov khoom siv kho tshuab yog siab dua 245, thiab lub zog tensile siab tshaj 265.
A105 carbon hlau flangeyog ib hom American standard carbon steel cov ntaub ntawv, ntau yam structural steel, xws li steel phaj, profile steel, thiab lwm yam. Nws cov ntsiab lus manganese kuj siab, thiab cov khoom siv hlau puag ncig hu ua 20Mn. Nws tuaj yeem pom tau tias nws cov ntsiab lus yog qhov siab tom qab cov ntsiab lus manganese. Txij thaum ntawd los, nws lub zog tensile thiab lub zog tawm los yuav siab heev, thiab nws cov khoom siv txhua yam yuav zoo dua. Lub zog tawm los ntawm A105 cov khoom siv raws li cov qauv dav dav yog ntau tshaj 300, thiab lub zog tensile yog ntau tshaj 500.
Nyob rau hauv Tuam Tshoj txoj kev lag luam xa tawm mus rau txawv teb chaws, ntau tus neeg siv khoom txawv teb chaws thiab cov neeg yuav khoom yuav xaiv cov khoom flange ntawm tus qauv American A105. Yog tias muaj lwm yam ntaub ntawv, yuav tau hais tshwj xeeb.
