ReflowX SKU: REF-7456
The 18-5/8" 87.5# X56 SL BOSS Seamless Casing (R3) is a premium-grade casing string engineered for robust structural integrity and leak-free performance in high-pressure drilling environments. Manufactured from X56 steel, this casing meets or exceeds the mechanical requirements of API 5L/5CT standards, delivering excellent tensile strength, burst and collapse resistance, and moderate corrosion tolerance.
The SL BOSS premium connection provides a high-performance thread-to-thread metal seal, optimized for torque handling, gas-tight sealing, and excellent fatigue resistance—ideal for deep wells, geothermal wells, HPHT operations, and wells requiring large-diameter structural support.
Supplied in Range 3 (R3) length (approx. 40–42 ft), this casing reduces the total number of connections per string, saving time and improving mechanical integrity during installation. Its seamless design ensures uniform material strength with no welded seams.
