Product Description

oilfield drill pipe

Drill pipe plays a decisive role in the process of drilling, it transfered the drilling torque to drill bit, in order to drilling under the well. When it is drilling,drill pipe has complicated load, at the same time it is subjected to stress such as pulling,pressing,torsion and bending, and drill pipe string itself is an elastic system, drilling fluid in the process of drilling and the vibration of the drilling string makes the drill pipe under a great load.

Drill Pipe Type:

E75、X95、G105、S135.
