Abstract
A die set used in pipe tongs in the oil and gas industry for gripping pipe while threadably coupling pipe joints, the die having electroless nickel plated, non-interrupted knurled teeth having a special shape which reduces die penetration, thereby reducing wall loss due to die penetration, stress cracking and carbon transfer to oil and gas field tubular pipe and especially to corrosive resistive alloy pipe, thus further reducing pipe corrosion.
