seamless steel raj

Seamless steel yeeb nkab yog ib hom hlau ntev nrog hollow seem thiab tsis muaj pob qij txha nyob ib puag ncig. Seamless steel yeeb nkab muaj qhov hollow seem thiab tuaj yeem siv los ua cov raj xa dej, xws li roj, nkev, roj, dej, thiab qee yam khoom siv. Piv nrog cov khoom hlau xws li cov hlau puag ncig, seamless steel yeeb nkab yog sib dua hauv qhov hnyav thaum nws khoov thiab lub zog torsional zoo ib yam. Nws yog ib hom kev lag luam steel, uas yog dav siv los tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li roj laum yeeb nkab, tsheb sib txuas ncej, tsheb kauj vab ncej thiab steel scaffold siv hauv kev tsim kho. Kev tsim cov nplhaib zoo li cov kav hlau tsis sib haum tuaj yeem txhim kho cov khoom siv tus nqi, ua kom yooj yim rau kev tsim khoom, thiab txuag cov ntaub ntawv thiab cov sijhawm ua haujlwm, xws li dov bearing rings, Jack tes tsho, thiab lwm yam, uas yog dav siv nrog cov kav hlau. Cov yeeb nkab steel kuj yog ib qho khoom siv tsis tau rau ntau yam riam phom. Lub thoob thiab lub thoob ntawm rab phom yuav tsum tau ua los ntawm cov yeeb nkab steel. Cov yeeb nkab steel tuaj yeem muab faib ua cov yeeb nkab puag ncig thiab cov yeeb nkab tshwj xeeb raws li cov duab ntawm qhov chaw hla ntu. Vim tias thaj chaw ncig yog qhov loj tshaj plaws nyob rau hauv qhov xwm txheej ntawm qhov sib npaug ntawm ib puag ncig, cov kua dej ntau tuaj yeem thauj tau nrog lub voj voog. Tsis tas li ntawd, thaum lub nplhaib seem raug rau sab hauv lossis sab nraud radial siab, lub zog ntau dua. Yog li ntawd, feem ntau ntawm cov raj steel yog cov raj ncig. Txawm li cas los xij, cov kav dej ncig kuj muaj qee yam kev txwv. Piv txwv li, nyob rau hauv cov xwm txheej ntawm lub dav hlau dabtsi yog khoov, lub zog dabtsi yog khoov ntawm cov kav dej tsis muaj zog npaum li cov kav dej square thiab lub voj voos. Cov kav dej square thiab cov duab plaub feem ntau yog siv nyob rau hauv lub moj khaum ntawm qee cov tshuab ua liaj ua teb thiab cov cuab yeej siv, steel thiab ntoo rooj tog, thiab lwm yam. Tshwj xeeb zoo li tus steel kav nrog rau lwm cov duab ntoo khaub lig-section kuj yuav tsum tau rau ntau lub hom phiaj.

Welded steel yeeb nkab

Welded steel yeeb nkab, tseem hu ua welded yeeb nkab, yog cov yeeb nkab steel ua los ntawm steel phaj lossis steel sawb tom qab crimping thiab sib sau. Welded steel yeeb nkab muaj qhov zoo ntawm cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, ntau yam thiab cov lus qhia tshwj xeeb thiab cov cuab yeej siv tsawg dua, tab sis nws lub zog dav dav yog qis dua li seamless steel yeeb nkab. Txij li thaum xyoo 1930, nrog rau kev txhim kho sai ntawm cov khoom siv zoo tshaj plaws thiab kev ua haujlwm ntawm vuam thiab tshuaj xyuas tshuab, cov vuam zoo tau raug txhim kho tas li, ntau yam thiab cov ntsiab lus ntawm cov kav hlau welded tau nce, thiab seamless steel kav. tau hloov nyob rau hauv ntau thiab ntau teb. Welded steel kav yog muab faib ua ncaj seam welded yeeb nkab thiab kauv welded yeeb nkab raws li daim ntawv ntawm weld.
