API 5L Qib X42 ERW Kab Yeeb

API 5L X42 welded pipe: API stands for the American Petroleum Institute, with "X" denoting the first letter of "pipeline" in English, capitalized; "42" indicates a minimum yield strength of >420 MPa rau. X42 pipeline yeeb nkab yog cov yeeb nkab yeeb nkab nrog qib steel ntawm X42, uas muaj qhov xaus, threaded xaus, thiab lub qhov (socket) xaus. Nws yog kev cob cog rua los ntawm vuam, coupling, qhov (socket) kev twb kev txuas, thiab lwm yam API 5L X42 welded yeeb nkab yog feem ntau siv nyob rau hauv kev tsim kho ntawm cov roj thiab cov nkev kis tau tus mob pipelines.
