9-5/8" 53.5# TN 110SS TSH BLUE Seamless Casing (R3) – High Collapse, Premium Thread

The 9-5/8" 53.5# TN 110SS TSH BLUE Seamless Casing (R3) is a high-performance casing solution engineered for critical well applications, including sour gas, high-pressure/high-temperature (HPHT), and deep well environments. Manufactured to API 5CT and Tenaris specifications, this casing features TN 110SS – a super sour service grade with enhanced collapse resistance and sulfide stress cracking (SSC) protection.

It is equipped with TSH BLUE® premium connections, known for metal-to-metal gas-tight sealing, high torque capacity, and excellent fatigue resistance, making it ideal for deviated and complex well trajectories. The casing is supplied in Range 3 (R3) length, providing longer joints (approx. 40–42 ft) to minimize connection frequency and enhance well integrity.

Engineered for structural integrity, tight sealing, and resistance to extreme downhole conditions, this casing is widely used in deepwater, shale, and sour gas field developments.
