7" 29# L80 TENARIS BLUE Casing – R3 Range, API 5CT Premium Connection

The 7" 29# L80 TENARIS BLUE Casing is a high-strength, corrosion-resistant tubular product designed for use in critical well environments, including sour gas, deep wells, and high-pressure/high-temperature (HPHT) completions. Manufactured from seamless steel and certified to API 5CT standards, this casing features the premium Tenaris Blue® connection for gas-tight, torque-resistant performance.

The L80 grade provides controlled yield strength and enhanced resistance to sulfide stress cracking, making it suitable for moderately corrosive environments. The Tenaris Blue connection offers superior sealability under tension, compression, and bending, making it a preferred choice for challenging downhole conditions.

Supplied in R3 range length (30–40 ft), the 7" 29# casing ensures reliable mechanical properties and operational safety in both onshore and offshore applications.
