Dab tsi yog Api 5L X70 yeeb nkab
X70 kab yeeb nkab yog cov khoom lag luam tshwj xeeb siv nyob rau hauv cov roj thiab roj kev lag luam rau kev thauj khoom xws li cov pa oxygen xws li API spec 5L thoob ntiaj teb tus qauv. Nws cov specifications npog sab nraud diameters ntawm 8-1240mm, cov phab ntsa thickness ntawm 1-200mm, thiab cov txiaj ntsig zoo nkauj ntawm 485MPA (70kpsi). Cov qhab nia tsim tawm ntau ntau ntawm B thiab X42 rau x70, thiab cov Molybdenum cov ntsiab lus tuaj yeem hloov kho (nce mus txog 0.35%) kom tau raws li kev xav tau sib txawv.
