Heavy Weight Drill Pipe
Heavy Weight Drill Pipe
Product Features
  • Fitting threads can be repaired several times.
  • Large wall thickness, increase the weight.
  • Outer diameter and the inner diameter of the pipe joints are consistent with ordinary drill bore is within the flat, at least equal to the inner diameter of the bore diameter of the drill collar. So, you can adapt processes and operations for drill or drill collars.
  • Middle segment of its small centralizer role, can adapt to the pressure generated by the deflection, more adaptable than the borehole drill collar bending. Only when bending thicker sections at both ends and the middle joint in contact with the wall, but also conducive to the anti- card tube from wear and tear.
  • Thickened portion at both ends of welded joints and central carbide or iron-based alloy powder, greatly extend the working life.
  • Prevent deformation of the compression coil , the outer diameter of the thickened central portion of the joint and to increase and increase the number of thickened middle portion, so that a uniform curved , with the well pipe body do not touch the walls .
  • The requirement for this is due to the thicker drill alternating bending stress, must have sufficient toughness, strength and stiffness comparable to prevent deformation of the coil and can withstand the axial and torsion loads.
Product Features

Drill bit

Tri cone drill bit

The drill bit is hollow and has jets to allow for the expulsion of the drilling fluid, or "mud", at high velocity and high pressure to help clean the bit and, for softer formations, help to break apart the rock. A tri cone bit comprises three conical rollers with teeth made of a hard material, such as tungsten carbide. The teeth break rock by crushing as the rollers move around the bottom of the borehole.
