API 5L X52 PSL2 carbon steel petroleum pipes feem ntau yog siv los thauj cov roj av, cov khoom ua kom zoo, thiab cov pa roj carbon monoxide los ntawm cov kav dej. API 5L cov kav dej kuj tseem siv rau hauv kev tsim kho cov refineries, natural gas processing plant, thiab lwm qhov chaw tseem ceeb.
Qhov "X" hauv API 5L X52 sawv cev rau qhov tsawg kawg nkaus tawm lub zog, uas yog 52000 psi, thiab nws qhov kawg tensile lub zog yog 66000 PSI. Tsis tas li ntawd, nws muaj qhov tsawg kawg nkaus elongation ntawm 21%, qhov ceev ntawm 7850 kg / m³, thiab melting point ntawm 1420-1460 degree .
