TC Carbon Steel Oilfield Sucker Rod Coupling

TC Carbon Steel Oilfield Sucker Rod Coupling is a versatile type of sucker rod coupling, strictly manufactured in compliance with API Spec 11B 28th Edition with precisely controlled mechanical properties. It reaches minimum tensile strength ≥655MPa and yield strength ≥414MPa to guarantee stable service performance.   We provide customizable alloy steel couplings and carbon steel sucker rod couplings to accommodate various downhole environments. TC carbon steel couplings feature remarkable cost advantages for shallow non-corrosive oil wells. Meanwhile, TA and TS alloy steel grades achieve balanced hardness and toughness with anti-galling threads to prevent thread failure, making them ideal choices for medium and deep high-pressure oilfields. A full range of polished rod couplings are kept in stock to enable seamless connection between sucker rods and wellhead polished rods for complete rod string assembly. We also supply wrench flat couplings and slimhole couplings to fit diverse in…
