API 5CT Standard Specifications
API Spec 5CT yog ib qho tseem ceeb ntawm kev lag luam tshwj xeeb tshaj tawm los ntawm American Petroleum Institute, siv los ua qauv seamless thiab welded casing thiab tubing (OCTG roj av- cov kav dej tshwj xeeb) siv hauv kev tshawb nrhiav roj thiab roj. Cov qauv no qhia meej meej txog kev faib qib steel, tshuaj lom neeg muaj pes tsawg leeg, ntsuas kev ua haujlwm zoo, qhov siab ntev, kev xav tau ntawm cov xov, cov cai ntsuas dej siab, tsis yog - cov txheej txheem kuaj kev puas tsuaj, kev txheeb xyuas cov khoom, thiab cov qauv kev lees paub rau cov khoom siv roj av.
API 5CT J55 yog ib qho ntawm cov ntsiab lus tseem ceeb tshaj plaws hauv cov qib casing steel. Cov qib steel qib J55 yog los ntawm nws qhov tsawg kawg nkaus yield zog ntawm 55,000 phaus ib square inch (379 megapascals). Piv nrog rau qib siab - qib steel xws li N80 thiab P110, J55 feem ntau yog tsom rau ntawm qhov chaw dej ntiav uas tsis muaj hydrogen sulfide corrosion. Nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum nco ntsoov tias qhov zoo tib yam J55 casing tsis tuaj yeem siv rau hauv acidic tej yam kev mob thiab muaj kev pheej hmoo ntawm sulfide kev nyuaj siab tawg; rau cov kua qaub-muaj thiab hydrogen sulfide-nplua nuj wellbores, los tiv thaiv- sulfur- cov qib steel tshwj xeeb yuav tsum raug xaiv.
