Longitudinal welded yeeb nkab yog ib hom steel yeeb welded raws nws ntev, machinery, thiab xa hluav taws xob thauj khoom. Ib tug nrov ntawm cov yeeb nkab no yog covCarbon Weld Steel Yeeb, paub txog nws cov nqi-ua hauj lwm zoo, kev ua tau zoo, thiab ntau yam kev siv. Vim nws cov txheej txheem ntau lawm, ua haujlwm siab, thiab tus nqi qis, nws tau dhau los ua kev xav tau. Txawm li cas los xij, piv rau muab kauv kav hlau welded, ntev welded kav dej muaj luv weld seams tab sis feem ntau qis zog. Yog li no, qee yam kev ntsuas yuav tsum tau coj los tiv thaiv kom tsis txhob tawg thaum siv.
Ua ntej, thaum siv cov kav dej ntev welded, suav nrog Carbon Weld Steel Yeeb, Nws yog ib qho tseem ceeb kom tsis txhob muaj kev sib cuag ncaj qha nrog qee yam ntaub ntawv. Piv txwv li, tso cov kav dej ua ke nrog cov pipoles steel yuav ua rau hluav taws xob corrosion, tshwj xeeb tshaj yog nyob rau hauv cov dej noo lossis dej-tsim ib puag ncig. Qhov kev ua kom nrawm nrawm nrawm nrawm ntawm cov hlau oxidation, txo nws lub zog thiab thaum kawg ua rau pob txha. Yog li no, thaum lub sij hawm cia thiab siv, cov khoom sib txawv hlau yuav tsum tau muab sib cais, xws li kev siv roj xeb, xws li siv cov ntaub ntawv insulating rau kev sib cais.
Thib ob, thaum tsim khoom, cov neeg tsim khoom ntawm cov kav dej ntev welditudinal, suav nrogCarbon Weld Steel Yeeb, feem ntau ntxiv cov ntaub ntawv alloy los txhim kho cov khoom siv cov khoom, xws li txhim kho corrosion tsis kam thiab tawv. Ib qho ntxiv, tom qab kos duab txias, kev ntxhov siab annealing feem ntau yuav tsum tau txo qis kev ntxhov siab hauv cov khoom siv. Kev ntxhov siab ntau dhau tuaj yeem ua rau cov kab nrib pleb lossis xwm txheej thaum siv. Los ntawm kev kho annealing, qhov ruaj khov thiab kev pabcuam lub neej ntawm cov yeeb nkab tuaj yeem hloov kho tau zoo.
Thaum kawg, tswj cov deformation ntawm cov kav dej ntev welded, suav nrogCarbon Weld Steel Yeeb, yog qhov tseem ceeb los txo txoj kev pheej hmoo ntawm pob txha. Txias kos duab deformation nce cov hlau hluav taws xob, tab sis ntau yam deformation tuaj yeem ua rau txo cov xim zoo nkauj thiab tawv, ua cov yeeb nkab ntau nrooj thiab muaj txiaj ntsig tawg. Tsis tas li ntawd, txias kos duab albat cov qauv nplej ntawm cov hlau, nce axial lub zog tab sis txo kom muaj zog radial. Txij li cov qauv zoo li cov thooj voos kheej kheej feem ntau cov kev ntxhov siab hauv cov kev taw qhia radial, ntau yam deformation tej zaum yuav ua rau cov yeeb nkab uas muaj peev xwm tiag tiag. Yog li ntawd, thaum lub sijhawm kev tsim khoom, deformation yuav tsum ua tib zoo tswj hwm kom cov khoom siv tshuab ntawm cov yeeb nkab uas yuav tsum ua haujlwm.
