Cov qib API2 x52 lsaw cov yeeb nkab tsis kam rau corrosion yog tiag tiag siab, uas ua rau lawv zoo zoo rau cov kev pab qaub. Nyob rau hauv cov dej khov, leej faj sulfur kev cuam tshuam corrosion yog qhov tshwm sim tshwm sim. Lub hydrogen lwg me ntawm hydrogen sulphide roj tau sib faib thiab muab tso rau ntawm cov phab ntsa ntawm API 5L X52 cov khoom siv yeeb nkab. Qhov no tuaj yeem ua rau API 5L Qib X52 Yeeb Nkab rau Phua lossis tawg. Txij li thaum API 5L X52 Seamless kav dej xws li API 5L X52 Ntawv Yeeb Nkab Tau Txais Los ntawm cov kev hloov pauv ntawm cov tshuaj lom neeg uas muaj nyob hauv X52 qib yeeb nkab.
