FAQ
Dab tsi yog qhov txawv ntawmL80thiab L80 Hom 1?
API 5CT Qib L80 yog cov ntsiab lus dav dav hais txog cov qib casing thiab tubing steel uas ua raws li API 5CT tus qauv thiab muaj qhov tsawg kawg nkaus lub zog ntawm 80 ksi (552 MPa); Thiab L80 Hom 1 yog ib hom tshwj xeeb (Hom 1) nyob rau hauv qib L80, nrog cov ntsiab lus tseeb thiab sib koom ua ke ntawm cov tshuaj lom neeg thiab cov khoom siv ua haujlwm, uas yog ib feem ntawm L80.
Qhov txawv ntawm API 5CT L80-1, L80-9Cr thiab L80-13Cr yog dab tsi?
Txawm hais tias API 5CT L80-1, L80-9Cr, thiab L80-13Cr belongs rau qib L80 steel (nrog rau qhov tsawg kawg nkaus lub zog ntawm 552 MPa), lawv muaj qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, kev tiv thaiv corrosion, thiab daim ntawv thov scenarios.
L80-1: Nws yog cov hlau tsis tshua muaj hlau uas muaj cov ntsiab lus chromium tsawg dua lossis sib npaug li 1.0% thiab tsis muaj qhov tshwj xeeb corrosion kuj. Nws yog tsim rau cov tsis muaj sulfur cov pa roj thiab roj qhov dej.
L80-9Cr: muaj li ntawm 8.5-9.5% chromium, nws muaj kev tiv thaiv zoo rau CO ₂ corrosion thiab haum rau nruab nrab corrosive ib puag ncig, xws li qhov tob tob uas muaj carbon dioxide.
L80-13Cr: Muaj 12-13.5% chromium thiab ntxiv cov ntsiab lus xws li molybdenum thiab npib tsib xee los ua "chromium-based passivation film". Nws muaj kev tiv thaiv zoo rau CO ₂, H ₂ S, thiab chloride ion corrosion, thiab tshwj xeeb yog tsim los rau cov dej tob lossis cov roj hauv hiav txwv nrog cov sulfur siab thiab acidity siab.
