Product Description
Stress Relief Groove & Bore Back Box
Stress relief grooves improve bending strength of pin and box connections and, therefore, durability.Stress relief grooves for box and pin are defined by API.
Bore back box is nothing but gradual reduction of internal diameter by gradually increasing material cross sectional area at critical section.This will ultimately reduce drastically stress concentration during Static / Dynamic loading and prevents box connections from failure.
Recommended Hardbanding Location
-Drill collars with slip and elevator recesses (ZIP)
4"long wear pad above elevator recess
1"long wear pad above slip recess.
10"long wear pad under slip recess
-Drill collars with slip recess:
10"long wear pad under slip recess,
4"long wear pad above slip recess.
-Drill collars without slip and elevator recesses:
10"long wear pad at 30"from pin shoulder.
