Drill Pipe
Introduction
Specification
Application: Used for oil well drilling, it is mainly used for the drilling process and after completion of borehole wall support, to ensure that the drilling process and the whole Wells after completion are normal runnings.
Applicable hard, very hard and medium soft rock formations.
Reliable quality, long service life, rare abnormal breakage during service life.
Good flushing effect to ensure high drilling rate.
Strict quality warranty and compensation rules.
