CRA yeeb nkab

Yog tias koj tab tom nrhiav data, zoo thiab ceev tus me nyuam oilfield cra xa hauv Tshuag, lossis yog koj muaj tswv yim yuav cra yeeb nkab API ntawm ib tus ua yeeb corrosion resistant alloy, cra lined kav manufacturers thiab lwm tus neeg Suav teb, thov yuav tiv tauj VIGOR.

CRA yeeb yog applicated rau cov ib puag ncig zoo deep uas muaj CO2.

Feem ntau, thaum lub siab hnov cov CO2 yog tshaj 30psiand corrosion siab rau arised, hlau qib alloyed mob npaws txheem ntawm Chromium, Molybdenum thiab npib tsib xee yuav siv tau rau ntawm resisting corrosion. 13Cr hlau OCTG yeeb siv 13% Chromium (13Cr) yog cov kim kawg corrosion-resistant alloy (CRA) tubulars uas yuav siv tau los tauj C02 corrision thiab H2S tej cracking inhibitor kho tsis tau. Cov hlau stainless tubulars raug nqi ntau npaum li ob lub tsev stainless hlau ib nrab xwb thiab ib-plaub mus caum ib tug ntau li ntau High School-npib tsib xee CRA ntaub ntawv. Siv 13Cr hlau OCTG yeeb tej zaum kuj yuav tsis tshua kim piv thiab tsis txhob kim tshaj koj siv cov/qes-alloy hlau rau inhibition. 13Cr kav hlau OCTG no kom zoo tshwj xeeb tshaj yog saib rau daim ntaub ntawv tubing rau ntau lawm offshore haujlwm uas ua hauj lwm qhov chaw yog tsawg thiab workover cov nqi yog siab. Tubulars siv 13% Cr muaj tau lug siv nyob hauv North America, North hiav txwv, Gulf of Mexico and nqes hav sab qaum teb ntawm Neeg Alaska.

13Cr hlau no raug tau corrosion thaum kub kub, los sulfidestress cracking (SSC) hauv ntsis siab H2S tej kev kawm thiab crevice corrosion. Vim li no, kev 13Cr hlau OCTG yeeb nkab yuav tsum tau ceev faj tubular tsim, ceev, tuav, cia, thiab haujlwm tom teb.
