API 5L qib B yeeb nkab yog dab tsi?
API 5L GRB seamless steel yeeb nkab yog cov khoom siv dav siv hauv kev thauj roj thiab roj.
API 5L yog tus qauv tsim los ntawm American Petroleum Institute (API) uas qhia txog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev, thiab kev ua haujlwm ntawm lub cev ntawm cov kav hlau. Qhov no ua kom tag nrho cov kav dej tsim nyob rau hauv cov qauv no ua tau raws li cov qauv zoo thiab kev ntseeg siab.
GR.B sawv cev rau qib nyob rau hauv tus qauv no, feem ntau yog siv rau roj thiab roj tsheb thauj mus los nyob rau hauv nruab nrab siab thiab kub tej yam kev mob. Nws muab zoo toughness thiab weldability. Qib GR.B feem ntau suav nrog cov ntsiab lus alloying xws li tooj liab, chromium, npib tsib xee, thiab titanium thaum lub sij hawm steelmaking los txhim kho nws cov corrosion kuj thiab thermal kev ua tau zoo, kom ntseeg tau ntev - lub sij hawm ua hauj lwm nyob rau hauv hnyav ib puag ncig.
Lub zog ntawm API 5L Qib B yog dab tsi?
API 5L Qib B cov kav dej feem ntau yog siv rau kev thauj mus los hauv cov kav dej hauv cov roj thiab roj. Lawv muaj qhov tsawg kawg nkaus yield zog ntawm245 megapascals (MPa)thiab lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa.
Qhov txawv ntawm API 5L X52 thiab Qib B yog dab tsi?
