13-3/8" 68# L80 BTC Seamless Casing (R3) – API 5CT Certified

The 13-3/8" 68# L80 BTC Seamless Casing (R3) is a high-strength, API 5CT-compliant casing string designed for use in high-pressure and sour gas environments. Manufactured from L80 steel grade, this casing offers excellent mechanical properties and resistance to sulfide stress cracking (SSC), making it suitable for critical applications in demanding drilling conditions.

Featuring Buttress Thread and Coupling (BTC) connections, the casing ensures a secure, pressure-tight joint. Its seamless construction enhances structural integrity and performance under axial and radial loads. The casing is available in Range 3 (R3) length, offering long joints (approx. 40–42 ft), preferred in deep drilling operations to minimize the number of connections.

This casing is currently offered for sale, auction, or private negotiation. Buyers are encouraged to inquire for full details, including quantity available, pricing, storage location, and mill certification.
