Weilida drill pipe joint is a key component for connecting drill pipes. It is made of high-strength alloy steel (such as 42CrMo and 35CrMo). After quenching and tempering, the yield strength is increased (up to 689-965mpa). The drill pipe joint is composed of a male joint and a female joint, and is interlocked through API standard threads (such as NC, reg, FH, if). The main and auxiliary shoulder structures form a double seal to ensure the stability under high pressure environment. The outer diameter of the joint is usually larger than the pipe body to enhance the wear resistance, and an anti-wear belt is set to reduce the friction loss.
