English
API 5CT N80 tubing pipe is a high-strength steel tube used in oil and gas wells, conforming to API (American Petroleum Institute) standards. It is designed for medium to high-pressure environments and offers superior mechanical properties compared to lower grades like J55. N80 tubing is heat-treated to enhance its tensile and yield strength, making it suitable for deeper wells and more challenging conditions.
This pipe is designed to provide structural support and is used in medium-pressure wells where there is a higher risk of collapse. It is suitable for a variety of well environments, including high-pressure and high-temperature wells, horizontal wells, and offshore drilling operations. The main function of N80 tubing is to safely transport fluids such as oil and gas from the bottom of the well to the surface.
