Kev nkag siab txog qhov sib txawv ntawm cov kav dej steel no tuaj yeem pab xyuas kom meej tias cov khoom siv zoo tshaj plaws rau qhov kev xav tau raug xaiv los ua kom zoo dua qhov kev ua tau zoo, nqi, thiab kav ntev.Txhua hom steel yeeb nkab muaj nws qhov tshwj xeeb zoo thiab cov kev txwv, thiab kev xaiv yuav tsum tau ua raws li cov kev xav tau tshwj xeeb thiab cov xwm txheej.
SMLS, ERW, LSAW, thiab SSAW txheej txheem hauv qhov Nutshell
SMLS (Seamless Steel Pipe) txheej txheem
Kev xaiv: High-quality steel billet ua raw khoom.
Cua sov: Kub lub billet mus rau ib tug haum dov kub.
Perforation: Lub rhuab billet yog ua tiav rau hauv lub raj xa dej hauv lub tshuab perforating.
Rolling / Stretching: Kev ua haujlwm ntxiv lossis kev kos duab txias los ntawm lub raj zeb kom tau txais qhov xav tau loj thiab phab ntsa tuab.
Txiav / Txias: Txiav rau qhov ntev thiab txias.
ERW (Electric Resistance Welded Steel Pipe) txheej txheem
Kev xaiv: Coil (steel coil) yog siv los ua raw khoom.
Txoj Kev: Cov hlau coil yog unrolled thiab tsim rau hauv ib lub raj los ntawm lub tshuab sib sau.
Vuam: High-frequency tam sim no yog siv los ua kom sov cov npoo ntawm qhov qhib los ntawm vuam electrode, ua rau lub zos melting ntawm cov hlau, thiab vuam yog tiav los ntawm lub siab.
Shearing: Lub welded raj yog sheared rau qhov ntev yuav tsum tau.
LSAW (Longitudinal Submerged Arc Welded Steel Pipe) txheej txheem
Kev xaiv: steel phaj yog siv los ua raw khoom.
Pre-bending: Pre-bending ob sab ntawm steel phaj.
Txoj Kev: Yob cov hlau phaj rau hauv ib lub raj.
Vuam: Butt welding raws longitudinal kev taw qhia ntawm lub raj siv submerged arc vuam.
Expanding / straightening: Xyuas kom tseeb thiab roundness ntawm lub raj txoj kab uas hla los ntawm mechanical expanding los yog straightening tshuab.
Txiav: Txiav rau qhov ntev uas yuav tsum tau ua.
SSAW (Spiral Submerged Arc Welded Steel Pipe) txheej txheem
Kev xaiv: Coil (steel coil) yog siv los ua raw khoom.
Kev Tsim Kho: Cov hlau kauj yog dov rau hauv cov yeeb nkab kauv hauv lub tshuab sib sau.
Vuam: muab kauv ob sab tsis siv neeg submerged arc vuam rau sab nraud thiab sab hauv ntawm lub raj tib lub sijhawm.
Txiav: Lub welded raj yog txiav mus rau qhov ntev yuav tsum tau.
