7" 32# T-95 TSH BLUE Seamless Casing – R3 Range, API 5CT

The 7" 32# T-95 TSH BLUE Seamless Casing is a high-strength oilfield tubular solution specifically engineered for high-pressure, high-temperature (HPHT) and sour service environments. Manufactured from quenched and tempered T-95 grade steel and conforming to API 5CT specifications, this casing offers superior tensile strength, enhanced collapse resistance, and excellent performance in CO₂ and H₂S environments.

The TSH BLUE connection, developed by Tenaris, is a premium, gas-tight threaded connection known for its outstanding sealing reliability, fatigue resistance, and easy field make-up. With its metal-to-metal seal and robust shoulder design, it ensures zero leak paths under extreme well conditions, making it ideal for critical casing strings in complex well architectures.

Delivered in seamless form and R3 range (typically 40.0–42.0 ft), this casing provides structural integrity and reduced connection frequency, supporting both vertical and deviated drilling operations.
