Drill pipe joint

Drill pipe joint is the welding joint on the drill pipe and an important part of the drill pipe. Teda drill pipe joints are made of high quality structural steel and heat treated with Teda proprietary technology. The threaded surfaces of drill pipe joints are machined by CNC lathes to ensure their interchangeability. The screw surface is copper plated and Phosphated to prevent adhesion. Mechanical properties meet or exceed API 5DP standards.

Characteristic:

Raw material quality

The raw material of drill pipe joint is AISI 4137H. Its physical properties meet the standard of high performance steel.

heat treatment

The drill pipe joint is forged and then treated by heat treatment furnace. Its overall mechanical properties far exceed the effect of medium frequency heat treatment on the production line.

Strong tenacity

The absorption energy of drill pipe joint is much higher than API 5DP standard.

Traceability

Drill pipe joints have traceable coding and recording
