Carbon SMLS yeeb nkab API5L X52

API 5L qib x52 lsaw yeeb nkab qhov kev tiv thaiv corrosion yog qhov siab heev, uas ua rau lawv zoo heev rau kev pabcuam qaub. Hauv qhov dej qaub, Sulfur stress corrosion yog ib qho tshwm sim. Cov hydrogen molecules los ntawm cov roj hydrogen sulphide tau sib cais thiab tso rau ntawm phab ntsa ntawm API 5L X52 Pipe Materials. Qhov no tuaj yeem ua rau API 5L Qib X52 Yeeb Nkab tawg lossis tawg. Txij li API 5L X52 seamless kav xws li API 5L X52 PSL1 Yeeb Nkab & API 5L X52 PSL2 yeeb nkab muaj kev tiv thaiv zoo heev rau corrosion, lawv tsis cuam tshuam los ntawm cov tshuaj hloov pauv uas tshwm sim hauv X52 Qib Yeeb Nkab.
