This type of tubing is primarily used for well wall support during oil and gas exploration and production to ensure the safety of the drilling process and the long-term stability of the well.The Q125 grade is the strongest tubing in the API 5CT tubing family and is suitable for use in oil and gas wells where higher strength and durability are required, especially in deep wells and high-pressure environments.
