Product Brief Introduction
1. Main features of API 5D drill pipe
High strength: This drill pipe is made of high-strength alloy steel and can withstand the tremendous pressure and torque during drilling.
High toughness: It has good toughness and can maintain stable drilling performance under complex geological conditions.
Corrosion resistance: After special anti-corrosion treatment, it can resist the erosion of drilling fluid and other corrosive media.
Easy maintenance: The design is reasonable, easy to disassemble and repair, reducing the cost and time of drilling operations.
