Engineered for performance in harsh downhole environments, these 5.5″ 23# JFE-HP2-13CR-110 JFELION couplings are made from Super 13 Chrome alloy (UNS S41426). Designed for superior corrosion resistance in sweet (CO₂) and mildly sour (H₂S) service, they perform reliably in temperatures up to 350°F and environments with moderate chlorides. With enhanced strength and durability compared to standard and Modified 13 Chrome, these couplings are ideal for high-pressure, high-temperature (HPHT) wells. Fully compliant with NACE MR0175/ISO15156 for sour service, they meet API 5CRA/ISO13680 standards and are classified as Group 1, Category 13-5-2 alloy. Perfect for critical downhole applications where reliability and resistance matter.
