ASTM A333 specification kuj tseem hu ua ASME SA333, qhov kev qhia tshwj xeeb no suav nrog cov nominal (nruab nrab) phab ntsa seamless thiab welded carbon thiab alloy steel yeeb nkab npaj rau kev siv ntawm qhov kub thiab txias thiab lwm yam kev siv uas yuav tsum tau ua kom tsis muaj zog.
Cov kav dej no feem ntau hu ua Low-Temperature Carbon SteelPipes (LTCS).
Cov kav hlau hlau feem ntau cog lus nyob rau hauv qhov kub thiab txias, vim tias cov kav dej sab hauv txo qis, uas cuam tshuam rau cov dej ntws los yog roj ntawm qhov siab tshaj plaws, vim tias cov khoom siv yuav ua tsis tiav, kom tsis txhob muaj qhov xwm txheej zoo li no, ASTM A333 specification tau tsim kom nws tuaj yeem tiv taus qhov kub thiab txias thiab zam qhov teeb meem no.
Siv 333 Qib. 6 cov kav dej welded kuj tseem siv tau vim lawv ua tau zoo heev vim muaj cov ntsiab lus carbon.
Txawm li cas los xij, feem ntau cov tuam txhab nyiam cov kav dej seamless vim tias kev txhim kho kev ua tau zoo tuaj yeem siab txog 20% thaum siv cov kav dej seamless es tsis txhob siv cov kav dej.
Cov kav dej tshwj xeeb no tau txais kev kho cua sov kom zoo li qub, uas yog lwm qhov zoo dua hauv kev siv cov kav dej ASTM A33, Normalizing yog cov txheej txheem uas cov khoom raug rhuab mus rau ib qho kub ntawm 815 Deg. C lossis ntau dua thiab tom qab ntawd tso cai rau txias rov qab ntawm chav tsev kub hauv qhov qhib cua.
Cov txheej txheem no tswj cov microstructure ntawm cov kav dej thiab ua rau txo qis hardness tus nqi thiab nce ductility.
FAQ:
1. Koj puas yog tuam txhab lag luam lossis chaw tsim khoom?
Peb yog cov chaw tsim khoom.
2. Koj lub sijhawm xa khoom ntev npaum li cas?
Yog tias nws nyob hauv Tshuag, nws feem ntau yog 7-15 hnub. Yog tias nws tsis nyob hauv Tshuag, nws yog 15-20 hnub, nyob ntawm seb cov khoom tshwj xeeb thiab ntau npaum li cas.
3. Koj puas muab cov qauv? Nws puas pub dawb lossis kuv puas yuav tsum tau them nyiaj ntxiv?
4.Q: Koj ua li cas kom peb lub lag luam tuav tau ntev -lub sij hawm thiab kev sib raug zoo?
A: Peb khaws cov khoom zoo thiab cov nqi sib tw kom ntseeg tau tias peb cov neeg siv khoom tau txais txiaj ntsig; peb hwm txhua tus neeg siv khoom thiab suav lawv ua peb cov phooj ywg, thiab peb ua siab dawb ua lag luam thiab ua phooj ywg nrog lawv. Txawm lawv tuaj qhov twg los.
