ASTM A333 Qib 8 uas tsis muaj qhov kub thiab txias seamless steel yeeb nkab yog cov khoom siv zoo steel yeeb nkab haum rau kev thauj mus los hauv cov cheeb tsam uas tsis tshua muaj kub.
Sab nraud txoj kab uas hla ntawm ASTM A333 Qib 8 seamless steel yeeb nkab yog 10.3-660mm, phab ntsa thickness ntau yog 1.24-59.54mm, thiab qhov ntev tuaj yeem kho raws li cov neeg siv khoom xav tau. Cov kav hlau steel ntawm qhov kev qhia tshwj xeeb no tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam sib txawv.
Los ntawm kev xaav ntawm daim ntawv thov teb, cov kav dej txias ASTM A333Grade8 tau siv dav hauv tshuaj, roj av, roj av thiab lwm yam lag luam. Nws qhov kev ua tau zoo yog ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig thiab tuaj yeem ua tau raws li cov kev xav tau ntawm kev thauj mus los hauv cov kav dej.
ASTM A333 Qib 8 yeeb nkabmuab los ntawm GNEE tau raug sim thiab ua tau raws li qhov yuav tsum tau muaj ntawm kev tsim khoom thoob ntiaj teb. ASTM A333 Qib 8 Seamless thiab Welded Pipes yog tsim nyob rau hauv ISO9001 cov chaw muaj ntawv pov thawj. Peb qhov nruab nrab muag txhua hnub ntim ntawm cov kav hlau hauv Tshuag yog kwv yees li 40 tons. Peb tuaj yeem muab ASTM A333 Chav Kawm 8 cryogenic siab yeeb nkab nyob rau hauv tus qauv thiab tsis-tus qauv qhov ntau thiab tsawg nrog lub sij hawm txhuas tsawg. Peb muab cov ntaub ntawv ua tiav cov khoom ntsig txog rau peb cov neeg siv khoom ua ntej xa khoom.
