Vuam teeb meem ntawm longitudinal welded steel yeeb nkab

Vuam plaub ntawm longitudinally welded steel kav tau faib raws li kev tsim ua. Cov yeeb nkab hlau yuav raug muab faib ua ob yam raws li cov txheej txheem tsim khoom: cov kav hlau tsis sib haum thiab cov kav hlau txuas hluav taws xob. Hluav taws xob welded steel kav tau muab faib ua hluav taws xob welded kav, arc welded (tsis kam welder) kav dej thiab tag nrho tsis siv neeg arc welded kav vim lawv txoj kev sib txawv vuam. Lawv muab faib ua ob hom: ncaj seam welded kav thiab kauv welded kav. Lawv muab faib ua cov nplhaib ua ke raws li lawv sab saum toj. Welded kav thiab tshwj xeeb-puab (square, tiaj tus, thiab lwm yam) welded kav. Vuam teeb meem ntawm qhov ntev-txuas welded steel kav txuas ntxiv muab faib ua hluav taws xob welded steel kav rau hauv qab siab hydrodynamic tsheb thauj mus los, muab kauv seam arc welded steel kav, tam sim ntawd chev welded steel kav, thiab hluav taws xob welded kav. Seamless spliced ​​steel kav yuav siv tau ntau yam ua kua thiab vapor pipelines. Raws li cov ntaub ntawv, cov kav hlau steel tuaj yeem faib ua cov kav dej, cov kav hlau txuas, cov kav hlau tsis xeb, thiab lwm yam raws li cov khoom siv yeeb nkab (piv txwv li alloy cov qauv hlau). Alloy tub ntxhais tau muab faib ua: cov tub ntxhais me me tsis sib xws, aluminium alloy qauv txheej, tub siab siab, thiab siab tawv hlab. Rolling bearing tube, siab kub thiab acid tiv taus stainless hlau raj, precision alloy (xws li Kovar aluminium alloy) tub ntxhais thiab nws lub siab kub alloy raj, thiab lwm yam. Raws li cov qauv txheej txheem, cov yeeb nkab steel tuaj yeem faib ua: cov yeeb nkab du (yeeb nkab xaus tsis muaj xov) thiab xov (yeeb nkab kawg muaj xov) raws li cov yeeb nkab kawg kev sib txuas. Lub raj hlau xaim tau muab faib ua: dog dig xaim raj thiab raj raj thickened hlau raj. Thickened hlau raj kuj tseem muab faib ua: txheej sab nrauv hom (nrog xov sab nraud), sab hauv thickened hom (nrog xov sab hauv) thiab sab hauv thiab sab nrauv hom (nrog cov xov sab hauv thiab sab nraud) thiab lwm hom hlau raj. Raws li cov ntawv xov, cov xov kab raj kuj tseem tuaj yeem faib ua: cov xov kab cylindrical lossis cone xov thiab cov xov tshwj xeeb thiab lwm cov raj xov.
