Seamless carbon steel yeeb nkab yog ib hom yeeb nkab siv dav hauv kev lag luam. Nws cov txheej txheem tsim khoom tsis koom nrog kev vuam, yog li lub npe "seamless". Cov yeeb nkab no feem ntau yog ua los ntawm cov khoom siv zoo carbon steel lossis alloy steel los ntawm kub lossis txias dov. Seamless carbon steel yeeb nkab yog dav siv nyob rau hauv ntau lub teb xws li roj, natural gas, tshuaj lom neeg kev lag luam, boiler, geological kev tshawb fawb thiab machinery manufacturing vim nws cov qauv thiab lub zog, raws li zoo raws li zoo siab tsis kam thiab kub tsis kam. Piv txwv li, seamless steel kav rau qis thiab nruab nrab siab boilers yog tsuas yog siv los tsim superheated chav kav, boiling dej kav thiab superheated chav kav rau locomotive boilers ntawm ntau yam tsawg thiab nruab nrab siab boilers. Thiab seamless steel kav rau kev kub siab boilers yog siv los tsim cov kav dej rau cov cua kub ntawm cov raj dej boilers nrog kev kub siab thiab siab dua. Tsis tas li ntawd, seamless carbon steel kav kuj tuaj yeem siv los tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li tsheb tsav tsheb, tsheb kauj vab ncej, thiab steel scaffolding hauv kev tsim kho. Vim qhov tshwj xeeb ntawm nws cov txheej txheem tsim khoom, seamless carbon steel kav tuaj yeem tiv taus siab dua thaum siv thiab tsis tuaj yeem tawm, yog li lawv tseem ceeb tshwj xeeb hauv kev xa cov kua dej.
Kev faib tawm ntawm seamless carbon steel kav yog tsim los ntawm kev tsim khoom thiab kev siv. Raws li txoj kev tsim khoom, seamless carbon steel kav yuav muab faib ua ob pawg: kub-kuav los tiag thiab txias-dov (kos). Kub dov seamless steel kav muaj xws li cov kav hlau dav dav, qis- thiab nruab nrab-siab boiler steel kav, high-pressure boiler steel kav, alloy steel kav, stainless hlau kav, roj av cracking kav thiab lwm yam, thaum txias-dov (kos) seamless steel kav muaj xws li carbon nyias-walled steel kav, alloy nyias-walled steel kav, stainless nyias-walled steel kav thiab ntau yam tshwj xeeb-zoo li tus steel kav. Cov specifications ntawm seamless steel kav feem ntau yog qhia nyob rau hauv millimeters ntawm sab kab thiab phab ntsa thickness. Cov ntaub ntawv muaj xws li cov qauv zoo tib yam thiab zoo carbon steel (xws li Q215-A rau Q275-A thiab 10 txog 50 steel), cov hlau tsis tshua muaj hlau (xws li 09MnV, 16Mn, thiab lwm yam), hlau alloy thiab stainless acid-resistant steel. . Kev xaiv ntawm cov ntaub ntawv no muaj feem xyuam rau lub zog, siab tsis kam thiab corrosion kuj ntawm cov kav dej, yog li yuav muaj cov khoom siv sib txawv hauv kev siv ntau yam. Piv txwv li, cov pa roj carbon tsawg xws li No. 10 thiab No. 20 steel feem ntau yog siv rau cov kav dej xa dej, thaum nruab nrab carbon steels xws li 45 thiab 40Cr yog siv los tsim cov khoom siv kho tshuab, xws li cov kev ntxhov siab ntawm cov tsheb thiab cov tsheb laij teb. . Tsis tas li ntawd, cov kav dej seamless steel yuav tsum tau tswj xyuas kom zoo thaum lub sijhawm tsim khoom, suav nrog kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg, tshuaj xyuas cov cuab yeej cuab yeej, ntsuas dej siab, thiab lwm yam. Kev tsim cov txheej txheem ntawm seamless carbon steel kav kuj tseem ceeb heev. Nws koom nrog ntau cov kauj ruam xws li perforation, kub dov, txias dov los yog txias daim duab ntawm ingots los yog cov hlab ntsha, thiab txhua kauj ruam yuav tsum muaj kev tswj kom meej kom paub meej qhov zoo ntawm cov khoom kawg. Piv txwv li, kev tsim cov kav dej kub-dov seamless steel kav yuav tsum tau cua sov lub raj xa dej kom txog li 1200 degrees Celsius, tom qab ntawd tho nws los ntawm lub perforator, thiab tom qab ntawd tsim cov yeeb nkab steel los ntawm peb-cov menyuam oblique dov, nruam dov lossis extrusion. Cold-dov seamless steel kav yuav tsum tau lub raj billet yuav tsum tau pickled thiab lubricated ua ntej txias dov (kos) kom ua tau raws li qhov xav tau qhov loj thiab cov duab. Cov txheej txheem ntau lawm no tsis yog tsuas yog ua kom muaj qhov zoo ntawm cov yeeb nkab steel seamless, tab sis kuj muab nws qhov zoo dua qhov tseeb thiab qhov chaw tiav. Nyob rau hauv kev siv, seamless carbon steel kav yog dav siv nyob rau hauv ntau industries xws li roj, roj, tshuaj lom neeg kev lag luam, hluav taws xob, tshav kub, dej txuag, shipbuilding, thiab lwm yam. Lawv yog ib feem tseem ceeb ntawm kev lag luam niaj hnub no. Txawm hais tias nyob rau hauv qhov kub thiab txias ib puag ncig lossis hauv cov xov xwm corrosive, seamless carbon steel kav tuaj yeem qhia lawv cov kev ua tau zoo thiab muab cov khoom lav rau kev ua haujlwm nyab xeeb ntawm ntau yam kev lag luam.
Txoj kab uas hla ntawm seamless carbon steel kav tuaj yeem nyob ntawm DN15 txog DN2000mm, phab ntsa thickness txawv ntawm 2.5mm txog 30mm, thiab qhov ntev yog feem ntau ntawm 3 thiab 12m. Cov kev txwv tsis pub muaj seamless carbon steel kav ua haujlwm ruaj khov nyob rau hauv kev kub siab thiab kub ib puag ncig, thaum tseem ua kom ntseeg tau lawv txoj kev ntseeg siab thaum thauj thiab teeb tsa. Raws li GB / T 17395-2008 tus qauv, qhov loj me, cov duab, qhov hnyav thiab qhov tso cai sib txawv ntawm cov kav dej seamless steel yog nruj me ntsis tswj xyuas kom cov khoom zoo thiab kev nyab xeeb. Thaum xaiv seamless carbon steel kav, nws yog ib qho tseem ceeb uas yuav tau xav txog lawv txoj kab uas hla, sab nraud txoj kab uas hla, thickness thiab ntev, uas yog ib qho tseem ceeb ntawm kev txiav txim siab kev ua tau zoo ntawm cov kav dej. Piv txwv li, txoj kab uas hla sab hauv txiav txim siab qhov loj ntawm qhov chaw rau cov kua dej dhau mus, thaum lub taub sab nraud thiab tuab yog ze ze rau lub siab-kev muaj peev xwm ntawm cov yeeb nkab. Qhov ntev cuam tshuam rau txoj kev sib txuas ntawm cov yeeb nkab thiab qhov nyuaj ntawm kev teeb tsa.
