Xaiv cov qib ntawm cov txheej txheem carbon steel seamount leeg yog qhov ua kom muaj kev ua tau zoo, thiav, thiab tus nqi zoo nyob rau hauv txhua qhov haujlwm.
1.Tiv tuabneeg cov pa roj carbon stand
Carbon Steel yog sib tov ntawm hlau thiab carbon. Nws tseem muaj cov nyiaj me me ntawm lwm cov ntsiab xws li manganese thiab silicon. Qee zaum, nws kuj tseem tuaj yeem muaj cov leej faj thiab phosphorus. Cov pa roj carbon cov ntsiab lus nyob rau hauv cov leeg no cuam tshuam lawv cov khoom siv, kev txiav txim siab lawv cov kev haum rau cov kev siv tshwj xeeb.
Qhov kev faib tawm ntawm Carbon cov qhab nia yog ua raws lawv cov ntsiab lus carbon:
Tsawg Tus Hlau:Muaj txog 0. 3% carbon. Nws muaj cov qauv ua kom zoo, Weldability, thiab kev nruj me, haum rau cov ntawv thov kom ua thiab dabtsi yog khoov.
Nruab Nrab Carbon Hlau:Muaj nruab nrab ntawm {{{0}}}. 3% rau 0.6% carbon. Cov qib no muaj lub zog siab dua thiab tawv tawv piv rau cov hlau roj carbon, ua rau haum rau cov ntawv thov cov khoom muaj peev xwm ntau dua.
High Carbon Hlau:Muaj ntau dua 0. 6% carbon. Siab carbon steel muaj hardness zoo heev thiab hnav tsis kam tab sis tej zaum yuav tsawg dua hlau thiab nyuaj rau Weld.
Alloy cov ntsiab zoo li manganese, silicon, thiab lwm tus ntxiv rau txhim kho cov khoom tshwj xeeb xws li lub zog, corrosion tsis kam, thiab machinity.
2.ommon cov qib ntawm cov roj carbon hlau seamless hlab
ASTM A106:

ASTM A53 Seamless Tubes muaj nyob hauv peb hom - hom F (txuas ntxiv welded), hom E (hom s (seamless).
API 5L:
API 5L yog qhov tshwj xeeb rau kev txhaum thiab welded steel kav haum rau kev xa roj, dej, thiab roj hauv cov roj av thiab roj av. Qhov qauv no suav nrog cov seamonless thiab welded carbon steel kav, nrog ntau qib voli 5l qib B thiab X42 rau x70, tsim rau cov kev thauj mus los tshwj xeeb.
ASTM AN179:
ASTM A179 tau tsim tshwj xeeb rau kev ua tsis taus rau seamless khaub thuas-carbon steel tshav kub sib pauv thiab condenser tub. Cov hlab yog siv dav hauv kev lag luam uas yuav tsum tau siv cov khoom cua sov vim lawv zoo heev thermal conductivity thiab corrosion tsis kam. ASTM A179 Seamless Tubes feem ntau yog siv rau hauv cov ntawv thov uas muaj kev hloov pauv cua sov, xws li hauv kev hloov cua sov, thiab cov condensers tshav kub.
Txhua ntawm cov qib kawm muaj cov yam ntxwv tshwj xeeb thiab cov yam ntxwv ua kom haum rau cov ntawv thov tshwj xeeb. Piv txwv li, ASTM A106 thiab API 5L cov chav kawm tau zoo dua rau cov kev siv roj siab thiab roj av, hos ait
3.Fact yam cuam tshuam cov qib xaiv
Ntau yam yuav tsum tau txiav txim siab thaum xaiv cov qib tsim nyog ntawm cov hlau ua kom loj me me hlab:
Cov Khoom Siv Neeg Kho Tshuab:Cov cuab yeej ua haujlwm yuav tsum muaj rau daim ntawv thov, suav nrog lub zog tensile, tawm lub zog, hardness, thiab yoog raws, sau dictate cov qib tsim nyog. Piv txwv li cov tub rog ua kom sov yuav tsum muaj lub zog thiab thermal conductivity khoom.
Ib puag ncig cov xwm txheej:Xav txog qhov chaw ua haujlwm xws li qhov ntsuas kub, cov av noo, thiab nthuav tawm cov khoom corrosive. Carbon cov qhab nia nrog ntxiv corrosion resistance ntsiab xws li chromium lossis npib tsib xee yuav tsim nyog rau qee yam kev mob.
Weldability thiab formability:Ua raws li cov txheej txheem fabrication thiab kev koom nrog hauv txoj haujlwm, xaiv qib uas muaj kev thaiv kom zoo thiab muaj txiaj ntsig zoo yam tsis muaj kev sib raug zoo.
Tus nqi cuam tshuam:Cov qhab nia sib txawv ntawm cov roj carbon hlau tuaj ntawm cov nqi sib txawv vim sib txawv vim muaj kev sib txawv thiab kev tsim khoom. Kev ntsuas kev ua tau zoo yuav tsum muaj cov kev txwv cov peev nyiaj txiag yog qhov tseem ceeb hauv kev xaiv cov kev xaiv raug nqi tshaj plaws.
4.Xaiv cov txheej txheem thiab kev sab laj
Kev Nkag Siab Thov:
Cov ntaub ntawv cov kws txawj tuaj yeem ntsuam xyuas cov kev cai tshwj xeeb, xws li qib kub, kom pom zoo cov pa roj carbon me me. Lawv xav txog qhov zoo li corrosion tsis kam, thermal conductivity, thiab kev kho tshuab zog los xyuas kom cov qib xaiv tau raws li lossis ntau dua qhov kev xav tau.
