Newly introduced ToughMet 3 Sucker Rod Couplings are "designed to maximize production output and significantly reduce the costs of artificial lift operations."
The patent pending designs are alternatives to those made of conventional materials. They cut frequency of sucker rod couplings and producing tubing damage - the leading cause of well failure. ToughMet 3 comprises a temper of copper-nickel-tin spinodal alloy engineered by this firm specifically to resist mechanical wear, thread damage, corrosion, or erosion. The couplings are nongalling to prevent damage to production tubing.
