| titleOfInvention | Process for manufacturing high performance tubulars and intercritically heat treated tubulars formed thereby |
| abstract | Abstract of the Invention A high performance carbon steel tubular for critical Oil Country applications and a process for its preparation are disclosed. The tubular is particularly adapted for use in deep wells where the tubular may be subjected to high pressure, wide temperature ranges, and/or corrosive environments, which may include hydrogen sulfide, carbon dioxide, and brine water, together with hydrocarbons. The process comprises forming the steel into tubular form, intercritically heat treating the form, removing surface defects, cold working the tubular form to finished dimensions, intercritically heat treating the tubular form, and quenching and tempering the finished tubular. |
