Tam sim no cov kav hlau steel nyob txhua qhov chaw hauv peb lub neej, tab sis yuav ua li cas xaiv cov kav hlau zoo rau peb siv? Cov yeeb nkab steel yog dav siv thiab muaj ntau hom. Cov kav hlau tuaj yeem muab faib ua ob pawg raws li kev tsim khoom: seamless steel kav thiab welded steel kav. Welded steel kav yog lub npe hu ua welded kav rau luv luv. Raws li txoj kev tsim, seamless steel kav yuav muab faib ua: kub dov seamless steel kav, txias-draw seamless steel kav, txias-dov precision seamless steel kav, kub-expanded kav, txias-spun kav thiab extruded kav. Seamless steel kav yog ua los ntawm high-zoo carbon steel los yog hlau alloy, thiab muab faib ua kub dov thiab txias dov (kos).
Welded steel kav tau muab faib ua rau hauv cov kav dej welded, hluav taws xob welded kav (ua haujlwm vuam) thiab tsis siv neeg arc welded kav vim lawv cov txheej txheem vuam sib txawv. Lawv tau muab faib ua cov kav dej ncaj nraim welded thiab kauv welded kav vim lawv txoj kev sib txawv vuam. Shape welded yeeb nkab thiab tshwj xeeb zoo welded yeeb nkab (square, ca, thiab lwm yam). Welded steel kav yog ua los ntawm dov steel phaj nrog pob tw los yog kauv seams. Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, lawv tau muab faib mus rau hauv lub low-pressure fluid thauj welded steel kav, kauv seam fais welded steel kav, ncaj kauv welded steel kav thiab hluav taws xob welded kav. Seamless steel kav siv tau rau cov kav dej pneumatic thiab cov kav dej hauv ntau qhov kev lag luam. Cov kav dej welded tuaj yeem siv rau cov kav dej, kav dej, cov kav dej cua sov, cov kav dej hluav taws xob, thiab lwm yam.
Muaj ntau ntau yam ntawm cov yeeb nkab steel, thaum xaiv, xav txog cov welded los yog seamless xwm ntawm cov yeeb nkab, yog li cia peb saib. Qhov sib txawv ntawm seamless yeeb nkab thiab welded yeeb nkab
Kev tsim khoom: Cov yeeb nkab yog seamless thaum nws dov los ntawm ib daim ntawv hlau rau hauv ib qho seamless zoo li. Qhov no txhais tau hais tias tsis muaj qhov khoob lossis seams hauv cov kav dej. Yooj yim los tswj dua cov kav dej welded vim tias tsis muaj qhov xau lossis corrosion ntawm cov pob qij txha.
Cov kav dej welded muaj ntau yam khoom uas tau welded ua ke los ua ib qho kev sib xyaw. Lawv hloov tau yooj yim dua li cov kav dej seamless vim tias lawv cov npoo tsis welded, tab sis lawv tseem ua rau cov xau thiab xeb yog tias cov seams tsis raug kaw zoo.
Nta: Thaum extruding cov yeeb nkab nrog tuag, cov yeeb nkab yuav dhau los ua cov duab elongated yam tsis muaj qhov khoob lossis cov seams. Yog li ntawd, seam welded kav yog muaj zog tshaj extruded kav.
Vuam yog siv cov khoom siv cua sov thiab muab tub lim los koom nrog ob daim hlau. Vim qhov txheej txheem corrosion no, cov hlau tuaj yeem ua nkig lossis tsis muaj zog thaum lub sijhawm.
