Tuam Tshoj Hom Tshiab Q235C Q235B 16Mn Welded carbon steel yeeb nkab / raj
Txheej txheem cej luam
Lub tuam txhab txhawb nqa lub tswv yim ntawm "Ua qhov saum toj kawg nkaus ntawm kev daws cov yeeb nkab", peb yuav txuas ntxiv ua haujlwm rau yav dhau los thiab tshiab cov neeg siv khoom los ntawm tsev thiab txawv teb chaws tag nrho-rhuab. Rau cov pa roj carbon steel welded lossis seamless yeeb nkab uas ua raws li ASTM A53 tus qauv, peb muaj ntau tshaj 30 xyoo kev yuav thiab muag, uas tuaj yeem lav peb muaj peev xwm ua kom txhua cov kav dej zoo.
Hais txog cov yeeb nkab seamless, muaj cov yeeb nkab tsis sib xws muaj nyob, uas yog cov cuab yeej cuab tam qis dua cov yeeb nkab seamless, vim tias nws yog tsim los ntawm ERW yeeb nkab, tom qab txheej txheem, nws cov vuam kab hloov mus ze li qhov tsis pom. Cov yeeb nkab zoo no tsis tuaj yeem dais siab, thiab lub zog tensile, kev ntxhov siab sab hauv txhua tus tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov yeeb nkab seamless. Nyob rau hauv rooj plaub no sib tov ob hom yeeb nkab, thov nco ntsoov tias ERW yeeb nkab tag nrho ua los ntawm cov hlau strips, yog li nws muaj cov phab ntsa tuab heev; seamless yeeb nkab yog tsim los ntawm puag ncig bar, perforate nyob rau hauv nruab nrab ntawm round bar los ua cov kav dej, yog li phab ntsa thickness tsis zoo li qub. Thiab cov kab txuas ntawm cov yeeb nkab tsis sib haum yog tseem muaj nyob, yog tias koj tshawb xyuas cov yeeb nkab hauv kev ceev faj, koj tuaj yeem pom nws.
Nws yog siv rau kev quab yuam thiab qhov siab, thiab rau lub hom phiaj dav dav, dej, roj thiab cov kav dej.
