Qhov txawv ntawm API 5L X52 thiab A106 GR B yog dab tsi - Kev Paub

API 5L X52 yog dab tsi?

API 5L X52 kab yeeb nkab yog siab - lub zog seamless thiab welded steel yeeb nkab dav siv hauv cov roj thiab roj tsheb thauj mus los. Nws cov kev ua tau zoo thiab kev ua tau zoo yog cuam tshuam ncaj qha rau kev nyab xeeb thiab kev ua haujlwm ntawm kev thauj mus los ntawm lub zog. Raws li cov ntaub ntawv tseem ceeb hauv API 5L tus qauv, X52 sawv cev rau kev tswj cov dov thiab tswj cov txheej txheem txias txias (TMCP) steel nrog qhov tsawg kawg nkaus lub zog ntawm 52,000 psi (kwv yees li 358 MPa), uas kuj muaj qhov zoo weldability thiab qis -kub toughness.
