16MnDG Tsawg Kub Seamless Steel Pipe piav qhia
16MnDG seamless steel yeeb nkab yog ib hom seamless steel yeeb nkab tshwj xeeb tsim rau qis- qhov kub thiab txias. Nws ua raws li cov qauv xws li GB/T18984-2016 thiab ASTM A333 series, thiab feem ntau yog siv nyob rau hauv qis-cov kav dej kub hauv petrochemical, lub zog, thiab lwm yam kev ua haujlwm ntawm qhov kub ntawm -45℃txog 195℃. Nws yog qhov tsim nyog rau cov hlab ntsha siab, cov khoom siv hluav taws xob sib hloov, thiab lwm yam khoom siv, thiab nws cov cuab yeej siv seamless ua kom muaj kev ruaj ntseg ntawm cov qauv thiab tsis kam ua rau tawg tawg hauv qhov kub thiab txias.
