Main Technical Features
● Traditionally the threads and the joint between the tube and the end-pieces are vulnerable. To
combat the problem we've friction-welded the joints for maximum strength and heat-treated
the end-pieces for optimum durability.
● Drill pipe is generally described by tube OD, nominal weight, pipe grade, type tool joint,
thread connection and classification.
● We do special heat-treating the threads ensures not only a long service life, but also simplifies
joining and breaking.
● Standard material for drill pipe is R780,but other material S135,G105 are available.
|Outer Diameter||Wall Thickness(mm）||Thread Pin/Box ||Length(meters)|
● Other specification drill pipes are also available upon request.
● Thread: API REG/IF or BECO or produced as customers requirements.
● All drill pipes are friction welded.
● Large sizes from 127mm to 500mm drill pipe are available.
