Case:
Globally, our C90 tubing has established a strong track record with successful deployments in diverse energy projects. It has been specified for critical sour gas production applications throughout the Middle East, selected for challenging shale formations across North American unconventional plays, and implemented in complex high-pressure well completions throughout Southeast Asia. This international adoption demonstrates the product’s consistent performance and reliability in meeting the most demanding operational requirements under API 5CT and NACE MR0175 standards for sour service applications.
