Botop Steel yog cov chaw tsim khoom lag luam thiab cov khoom lag luam ntawm cov yeeb nkab steel thiab cov raj hauv Suav teb, peb npaj thiab muab cov pa roj carbon seamless yeeb nkab rau cov kua thiab roj av daim ntawv thov nyob rau hauv qhov loj ntawm 10 OD txog 660 OD nyob rau hauv thickness ntau ntawm 1mm mus rau 100mm.Peb tsim cov pa roj carbon LSAW steel kav nruj raws li tus qauv thoob ntiaj teb xws li ASTM, API & DIN.Peb muaj ntau tshaj 8000 tons seamless kab yeeb nkab hauv Tshuag txhua hli, feem ntau peb tuaj yeem xa cov khoom tam sim ntawd.Txawm li cas los xij, tshwj xeeb, yog tias Tshuag ntawmcarbon steel kavtsis muaj peb tuaj yeem xa cov khoom nrog lub sijhawm luv tshaj plaws los ntawm cov chaw zeb hauv zos lossis ntshuam
Tag nrho pebcov kav hlauthiab cov khoom siv raj tau muab nrog 3.1 cov ntawv pov thawj tshwj xeeb, raws li EN 10204. Daim ntawv pov thawj raws li 3.2 tuaj yeem pom zoo thaum lub sijhawm xaj.Kev tshuaj xyuas thib peb tau txais (BV, SGS, thiab lwm yam)
Tus naj npawb txaus ntawm qhov muag pom qhov tsis zoo rau
