Drill Pipe for Oil Industry

Drill pipes that we supply for oil industry are available in a wide range of specifications.

Features
1. Friction welding drill pipes made of high quality structural steel, with upsetting treatment to the pipe ends after non-destructive testing and performance testing and with whole length thermal treatment after upsetting to improve toughness and strength.
2. Tool joints of the oil drill pipes are made using higher strength structural steel than the body.
3. Threads are turned in a high precision CNC lathe and accept heat treatment to fit with the body and tool joints in toughness and strength.
