Types of dies and inserts offered:
Steel dies and inserts with conventional bi-directional and uni-directional
tooth forms:
-
general purpose application for commonly used grades of carbon steel Oilfield
Country Tubular Goods (OCTG) and drillpipe, drill collars and accessories
-
tong dies with "diamond" style tooth form provides increased gripping for
higher strength tubulars and drillpipe, drill collars and accessories
Steel dies and inserts with specialized tooth geometry made on request:
-
fine tooth or continuous tooth increases contact area to reduce penetration
-
alternate or skipped tooth reduces number of teeth to increase contact pressure
GRIT FACE™ dies and inserts:
-
Used with all grades of Corrosion Resistant Alloy (CRA) stainless to provide
minimal marking and protection against contamination by carbon steel inserts
-
Used with all types of OCTG especially high strength materials such as API
Grade V-150 and 13% SuperChrome or HyperChrome that are difficult to
effectively grip with standard inserts
Inserts with Grit Coated teeth:
-
Used in recovery applications where CRA tubulars are coated with thick layer of
scale, asphaltines or similar materials which could foul standard GRIT FACE™
dies and inserts
GRIT FACE™ dies and inserts are produced using specially graded tungsten carbide
particles and nickel/chrome brazing process to provide an extremely hard
uniform surface to grip the highest strength carbon steel and CRA tubular
goods. The uniform gripping surface assures minimal marking with very
shallow, randomly distributed pattern to avoid stress risers left by other
gripping systems. The materials used to produce GRIT FACE™ dies and
inserts do not contain any free iron which might contaminate CRA tubulars and
cause potential premature corrosion failures.
The tungsten carbide gripping media will provide a long service life as it is
much harder than the strongest tubular goods being used in the oil patch
today. Like conventional inserts, the key to exceptional performance and
long service life of GRIT FACE™ dies and inserts requires these inserts be
periodically cleaned during the job using high pressure water blast, wire
brush, safety solvents or similar means.
