The friction welded drill pipe body is made of high-quality alloy structural steel material. After qualified non-destructive testing and performance inspection, the rear end is upset, and the full-length heat treatment after upsetting improves the toughness and strength of the pipe body. The strength of the drill pipe joint is better than High-quality alloy structural steel of tube body material. The threads are machined on a high-precision CNC lathe, and the thread parts are heat treated to meet the toughness requirements of the rod body and the strength requirements of the joint.
Friction Welding API Drill Pipe features:
1. High-precision CNC lathe processing to ensure the tightness of the thread connection;
2. Special heat treatment process to ensure that the connecting thread has sufficient strength and wear resistance;
3. The body of the drill rod and the joint are welded by a friction welding process, and then the intermediate frequency return is used to remove the welding stress to ensure the welding strength and the straightness of the finished drill rod.
4. The drill rod body and joint are made of European and American high-quality raw materials to ensure the superiority of normal construction under harsh conditions.
