4-1/2" 12.6# T95 TSH BLUE Seamless Casing (R3) – Sour Service, Premium Thread, API 5CT

The 4-1/2" 12.6# T95 TSH BLUE Seamless Casing (R3) is a premium-grade casing string designed for use in high-pressure, sour service, and directional well applications. Manufactured to API 5CT standards, it uses T95 quenched and tempered steel, providing excellent resistance to sulfide stress cracking (SSC) and ensuring long-term structural integrity under extreme downhole conditions.

Equipped with TenarisHydril TSH BLUE® premium connections, this casing ensures metal-to-metal gas-tight sealing, superior torque handling, and excellent resistance to bending and compression. The R3 length (approx. 40–42 ft) helps reduce the number of connections, improving well integrity and efficiency in deep wells.

This product is ideal for intermediate or production casing in sour environments, HPHT wells, and other critical zones requiring a secure, high-performance casing solution.
