X52 yeeb nkab yog qib nruab nrab roj thiab roj pipeline steel yeeb nkab uas ua tau raws li API 5L thiab ISO 3183 specifications. Nws cov specifications thiab kev ua tau zoo yog raws li nram no:
Specifications: Lub cheeb ntawm X52 yeeb nkab yog li ntawm 2 ntiv mus rau 80 ntiv tes (kwv yees li 50.8 hli txog 2032 hli), thiab phab ntsa thickness yog li ntawm 7 hli mus rau 100 hli.
Material Standard: X52 yeeb nkab ua tau raws li API 5L tus qauv thiab haum rau cov roj thiab cov kav dej. Tus qauv qhia txog cov kev cai rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab cov txheej txheem tsim khoom ntawm cov kav dej.
Kev ua tau zoo: X52 yeeb nkab muaj zog compressive thiab corrosion kuj, thiab yog haum rau thauj high-pressure thiab high-temperature roj thiab roj. Nws lub zog tawm los yog feem ntau ntawm 413MPa thiab 620MPa.
Tsis tas li ntawd, X52 yeeb nkab feem ntau siv rau hauv kev thauj mus los hauv cov roj thiab cov roj rho tawm kom ntseeg tau tias kev ua haujlwm ruaj khov hauv qhov chaw ua haujlwm hnyav.
