API 5CT L80-9Cr Casing thiab Tubing
Kev Piav Qhia Luv:
Cov kav dej thiab cov kav dej API 5CT L80-9Cr uas ruaj khov thiab tiv taus xeb rau cov qhov dej roj qaub. Zoo tagnrho rau CO₂ thiab H₂S ib puag ncig.
L80-9Cr Casing thiab Tubing:
L80-9Cr casing thiab tubing yog cov khoom OCTG qib siab tshaj plaws tsim tawm raws li API 5CT specifications. Nrog 9% chromium cov ntsiab lus, cov khoom siv no muaj kev tiv thaiv zoo rau CO₂ thiab H₂S corrosion, ua rau nws zoo tagnrho rau kev siv cov kev pabcuam sour hauv cov roj thiab cov roj av qhov dej. Nrog lub zog zoo heev thiab kev kho cua sov quenched thiab tempered, L80-9Cr ua kom muaj kev ua haujlwm ntev hauv qhov chaw siab, kub siab. Muaj ntau qhov ntau thiab tsawg, hom xov, thiab qhov ntev (R1–R3), peb cov kav dej L80-9Cr ua tau raws li qhov xav tau ntawm cov haujlwm offshore thiab tob qhov dej.
