  • Pipe die method and apparatus
    Publication number: 20040207223
    Abstract: A die used in slip and elevator assemblies in oil and gas drilling operations for gripping tubular members while coupling and uncoupling joints, the die including electroless nickel plated, non-interrupted knurled teeth with a truncated pyramid shape and a dimple therein which reduces die surface penetration, thereby reducing wall loss due to die penetration, stress cracking, and carbon transfer leading to acid corrosion in oil and gas field tubular members and especially to corrosive resistive alloy tubular members.
    Type: Application
    Filed: April 21, 2003

  • Pipe gripping die
    Patent number: 5971086
    Abstract: A method for the construction of die members used in slips and elevators in the oil and gas industry for griping pipe. The die having nickel plated teeth with no mud grooves reduces die penetration thereby reducing stress cracking and carbon transfer in nickel alloy pipe thus reducing pipe corrosion.
