API Steel Pipe can be classified into different steel grades based on their inherent strength, including J55, K55, N80, L80, C90, T95, P110, Q125, and V150 for tubing and casing. Different well conditions and depths require the use of specific steel grades.
In corrosive environments, tubing and casing must possess corrosion-resistant properties. Additionally, in areas with complex geological conditions, API seamless casing is required to have collapse resistance.
