Integral Heavy Weight Drill Pipe
The Integral heavy weight drill pipe is made from AISI4145H alloy steel, and completely meets the requirement of API Spec 7-1 and SY/T5146 Standard. It is mainly used between dill collar and dill pipe to ease transition stress concentration and reduce the rate between contact area and outer wall wear, which can effectively prevent the pressure sticking.
