Feem ntau siv thoob ntiaj teb steel yeeb nkab qauv
1, ASTM A53: Standard specification rau yeeb nkab, hlau, dub thiab kub-dipped, zinc-coated, welded thiab seamless. Cov qauv no siv tau rau ob qho tib si welded thiab seamless steel kav siv rau kev xa cov kua ntau yam.
2, ASTM A106: Txuj kev qhia tshwj xeeb rau seamless carbon steel yeeb nkab rau kev pabcuam kub. Cov qauv no siv tau rau seamless carbon steel kav siv rau kev siv kub.
3, DIN EN 10216-2: Seamless steel raj rau lub hom phiaj siab - Cov txheej txheem kev xa khoom - Ntu 2: Cov hlau tsis muaj hlau thiab cov hlau tsis muaj hlau nrog cov khoom ntsuas kub siab. Cov qauv no siv tau rau seamless steel raj siv los tsim cov khoom siv siab thiab cov kav dej.
4, JIS G3454: Carbon steel kav rau kev pabcuam siab. Cov qauv no siv tau rau cov kav dej carbon steel siv rau kev pabcuam siab ntawm qhov ntsuas kub txog li 350 degree.
5, API 5L: Specification rau Kab Yeeb. Cov qauv no muaj feem xyuam rau cov kav hlau uas siv rau kev thauj cov pa roj, dej, thiab roj hauv kev lag luam roj av thiab ntuj tsim.
Hauv kev xaus, cov qauv steel yeeb nkab yog qhov tseem ceeb rau kev ua kom zoo thiab kev ua haujlwm ntawm cov kav hlau steel hauv ntau yam kev siv. Cov qauv hauv tsev thiab thoob ntiaj teb muaj lawv tus kheej cov ntawv thov tshwj xeeb, thiab nws yog ib qho tseem ceeb uas yuav tsum xaiv cov qauv tsim nyog raws li cov kev xav tau tshwj xeeb ntawm txhua qhov project.
