API 5L X52 muaj lub zog tawm los ntawm 360MPa txog 530MPa. Yield zog yog tus nqi kev ntxhov siab thaum cov khoom pib deform plastically nyob rau sab nraud quab yuam. Rau cov kav hlau steel, cov khoom muaj zog ncaj qha cuam tshuam rau lawv lub peev xwm los tiv taus siab thiab kev nyab xeeb.
Kev cuam tshuam ntawm cov khoom muaj zog ntawm API 5L X52 seamless steel kav
Lub peev xwm muaj peev xwm siab: Lub zog siab dua, lub peev xwm ntawm cov yeeb nkab steel muaj zog tuaj yeem tiv taus sab nraud, thiab nws tuaj yeem nyob ruaj khov nyob rau hauv kev kub siab kom muaj kev nyab xeeb ntawm kev thauj mus los.
Kev nyab xeeb thiab kev ntseeg tau: High yield zog txhais tau hais tias cov yeeb nkab steel tsis yooj yim rau cov yas deformation thaum raug rau sab nraud quab yuam, yog li txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm tag nrho cov qauv.
Daim ntawv thov scenarios: API 5L X52 seamless steel kav yog dav siv nyob rau hauv cov roj drilling, roj thiab roj tsheb thauj mus los, thiab refineries vim lawv siab yield zog, thiab muaj peev xwm ua hauj lwm ruaj khov rau lub sij hawm ntev nyob rau hauv qhov chaw ua hauj lwm huab.
Cov kev ua tau zoo no siv rau API 5L X52 seamless steel kav nrog ib txoj kab uas hla ntawm 21.3mm ~ 1200mm thiab phab ntsa tuab ntawm 2mm ~ 130mm. Cov txheej txheem ntau lawm suav nrog kev kos duab txias, kub dov thiab kub nthuav dav, thiab cov xwm txheej xa tuaj tuaj yeem kub dov lossis kho cua sov.
