PLATINUM™ HB
- The First Engineered Hardband Solution.
SUPERSMOOTHX® - Grant Prideco's patented solution for
applications requiring both tool joint wear protection and a machine-finished
tool joint.
SMOOTHX® A patented hardfacing of submerged spherical tungsten
carbide granules in a mild steel matrix providing a smooth surface with little
or no exposed carbide.
Grant Prideco 1000 SERIES® - For open hole applications,
the 1000 SERIES provides economical tool joint protection where casing wear is
not a primary concern.
In addition, Grant Prideco can provide a custom engineered hardfacing system
to meet requirements you specify.

SMOOTHX® Hardfacing
SMOOTHX was developed to minimize tool joint wear.
Five bands of
the SMOOTHX are applied around the tool joint, covering approximately 3 1/2 to 4
inches of length. Three "fingers" of SMOOTHX are applied to the elevator
shoulders to prevent wear and undercutting adjacent to the last band of
hardfacing. Without these fingers, the elevator shoulder could erode, shortening
the tool joint's life.
SMOOTHX is applied in a machined groove on the tool joint by dropping a measured
quantity of spherical shaped, sintered, 30-14 mesh, tungsten carbide granules
into a molten puddle formed by welding wire. The granules sink into the molten
weld metal and leave a smooth surface that has little or no exposed tungsten
carbide. The resulting matrix has an increasing density of tungsten carbide from
the surface to the bottom of the deposit.

SUPERSMOOTHX® Hardfacing with a "Machine-Finish" Surface
SUPERSMOOTHX was developed to meet the surface finish requirements of many North
Sea operators.
SUPERSMOOTHX is composed of an initial layer of SMOOTHX
applied in slightly deeper pre-machined grooves. A second layer of mild steel is
then deposited on the top. The mild steel overlay is then machined to produce
the same diameter and surface finish as the GD of the tool joint. The
"machined" finish minimizes contact stress.
SUPERSMOOTHX meets the toughest surface finish requirements in the industry.
