Home Products High Performance Alloys ToughMet Alloys Oil and Gas Sucker Rod Couplings TOUGHMET® SUCKER ROD COUPLINGS CHANGE THE GAME "Since installation nearly two years ago, none of the wells using ToughMet couplings have experienced a failure related to couplings, more than tripling the mean time between failures." - Production Engineer, Hess Corporation The game-changing, proven technology of ToughMet 3 Sucker Rod Couplings provides the most cost-effective solution for eliminating production interruptions caused by sucker rod coupling and production tubing failures in deviated shale wells. Almost half of the failures in these wells are related to either tubing or sucker rod coupling failures, caused primarily by wear damage resulting from couplings contacting the inner tube wall. The costs of working over wells run into the hundreds of millions of dollars per year. The new couplings last twice as long as couplings made of conventional materials, saving tens of thousands of dollars per well, per year.

For the sucker rod couplings, we developed a new ToughMet TS 95 temper that offers: Increased fatigue strength Increased fracture toughness ToughMet 3 Sucker Rod Couplings resist mechanical wear, thread damage, corrosion and erosion. They are non-galling to steel, so they do not damage production tubing, and they retain their strength even at elevated temperatures. TOUGHMET® 3 TS 95 ALLOY PROPERTIES: > 95 ksi tensile yield strength 65 ksi fatigue limit 30 ft-lb Charpy Impact Energy Resistant to chloride SCC, pitting and crevice corrosion Resistant to erosion, HE, SSC and general corrosion (including in mildly sour wells) To learn more about ToughMet TS 95 alloy properties, download our datasheet.
