Seamless cov yeeb nkab hlau yog ib hom yeeb nkab dav hauv kev muaj lag luam. Nws cov txheej txheem tsim khoom tsis koom nrog cov vuam, li no lub npe "seamless". Hom yeeb nkab no feem ntau yog ua los ntawm cov roj carbon zoo carbon cov hlau lossis alloy steel los ntawm kub lossis txias dov. Seamless cov yeeb nkab hlau yog dav siv nyob rau hauv ntau daim teb, cov roj txheem kev lag luam thiab kev tsim khoom zoo nkauj thiab kev tsim kho hluav taws xob thiab lub zog, nrog rau kev ua haujlwm zoo. Piv txwv li, cov kav dej steel tsis siv rau cov kav dej khov thiab cov kav dej npau npau rau cov kav dej khov thiab nruab nrab ntawm cov kav dej. Thiab seamless steel kav rau kev kub siab boilers yog siv los tsim cov kav dej rau cov raj dej raj boilers nrog kev kub siab thiab saum toj no. Ib qho ntxiv, Seamless Cov Pauv Steel Kav kuj tseem siv tau los tsim cov qauv txheej txheem thiab cov tshuab hluav taws xob, xws li cov tsheb kauj vab tsheb, thiab cov hlau scaffolding hauv kev tsim kho. Vim yog qhov tshwj xeeb ntawm nws cov txheej txheem tsim qauv, seamless cov pipes tuaj yeem tiv lub siab dua thaum siv tau, yog li lawv yog qhov tshwj xeeb hauv cov kua dej.
Kev faib tawm ntawm Seamless cov roj carbon hlau kav yog tsuas yog raws cov ntaub ntawv tsim khoom thiab siv. Raws li txoj kev ntau lawm, Seamless cov pipes steel tuaj yeem faib ua ob pawg: kub-dov thiab txias-dov (kos khaub ncaws txias (kos). Kub-Rolled Seamless Steel Kav Muaj suav nrog cov kav dej steel, cov roj av muaj roj av highter steel Seamless steel kav suav suav nrog carbon thiav-walled steel kav hlau, hlau nyias-walled nyias-walled steel kav hlau kav thiab ntau yam zoo li tus kheej hlau kav hlau. Cov kev qhia tshwj xeeb ntawm Seamless Steel kav yog feem ntau qhia nyob rau hauv millimetres ntawm sab nraud uas lub taub thiab phab ntsa tuab. Cov ntaub ntawv suav nrog cov roj carbon zoo thiab zoo li Q215-a rau Q215-A txog 09MNV, muaj lwm yam), alloy steel thiab stainless acid-resistant hlau Cov. Kev xaiv ntawm cov ntaub ntawv no cuam tshuam nrog lub zog, siab tsis kam thiab corrosion tsis kam ntawm cov raj dej yuav tsum muaj nyob hauv cov ntawv thov sib txawv. Piv txwv li, cov hlau tsis tshua muaj roj xws li No. 10 thiab Tsis Muaj. 20cr yog siv los tsim cov khoom siv roj carbon monoman, xws li cov kabmob nruab nrab ntawm cov tsheb thiab tsheb laij teb Cov. Ib qho ntxiv, cov kav hlau sib txuas yuav tsum tau kev tswj hwm nruj me ntsis, suav nrog lawv txoj kev ntseeg tau thiab kev nyab xeeb nyob rau hauv ntau yam kev ua haujlwm. Cov txheej txheem ntau lawm ntawm Seamless cov pa roj carbon hlau kuj tseem ceeb heev. Nws cuam tshuam nrog ntau cov kauj ruam xws li perforation, kub dov, thiab txhua kauj ruam yuav tsum tau tswj kom paub tseeb tias cov khoom kawg. Piv txwv li, kev tsim cov kub-rolled seamless steel kav yuav tsum muaj cua sov billet, ces tsim cov yeeb nkab hlauv yas, tom qab ntawd cov roj hmab oblique dov, txuas ntxiv yob lossis extrusion. Txias-dov seamless steel kav yuav tsum tau lub raj billet kom raug cov khaub ncaws ntim thiab lubricated ua ntej tau txias rolled (kos) kom ua tiav qhov xav tau loj thiab cov duab. Cov txheej txheem ntau yam nyuaj no tsis tsuas yog ua kom muaj qhov zoo ntawm cov yeeb nkab uas tsis zoo thiab tab sis kuj tseem ua kom zoo dua qub thiab qhov tseeb ua tiav. Hauv kev siv cov tswv yim, seamless cov kav hlau steel yog siv ntau li roj, hluav taws xob, hluav taws xob, tshuaj ntsuab, thiab lwm yam thiab kev ntseeg tau. Lawv yog ib feem ntawm qhov tsis tseem ceeb ntawm kev lag luam niaj hnub. Seb puas nyob rau hauv cov pa hluav taws kub thiab hauv cov khoom siv corrosive, seamless cov pipes tuaj yeem qhia lawv cov kev ua tau zoo thiab muab cov khoom muaj kev nyab xeeb rau kev ua haujlwm zoo ntawm ntau yam kev lag luam.
Qhov txoj kab uas hla ntawm seamless cov pipes tuaj yeem los ntawm DN2000mm, lub phab ntsa tuab sib txawv los ntawm 2.5mm, thiab qhov ntev feem ntau yog nyob ntawm 3 thiab 12m. Cov kev ntsuas no tso cai rau Seamless cov pupbon cov kav hlau ua haujlwm ua haujlwm ruaj khov nyob rau hauv ib puag ncig ntawm kev kub siab thaum lub sijhawm kev thauj mus los thiab installation. Raws li GB / T 17395-2008 tus qauv, qhov loj me, qhov hnyav, kev sib txawv ntawm cov kav hlau uas tsis muaj txiaj ntsig los ua kom cov khoom lag luam zoo thiab muaj kev nyab xeeb. Thaum xaiv cov pipol tsis zoo, nws yog ib qho tseem ceeb kom txiav txim siab lawv cov taub sab hauv, thickness thiab ntev, uas yog qhov tseem ceeb yam hauv kev txiav txim siab ntawm cov raj xa dej. Piv txwv li, lub taub hau sab hauv txiav txim siab qhov loj me ntawm cov kua dej kom dhau mus, thaum cov txheej txheej ua kom zoo sib xws ntawm cov yeeb nkab-cov yeeb nkab-cov yeeb nkab. Qhov ntev cuam tshuam rau txoj kev sib txuas ntawm cov yeeb nkab thiab cov nyom ntawm lub installation.
