Description

13% Chrome OCTG – Casing & Tubing (3-1/2", 4-1/2", 5-1/2", 7"), API 5CT

13% Chrome (13Cr) OCTG products are high-alloy, corrosion-resistant casing and tubing solutions engineered for use in CO₂-rich and mildly sour oil and gas environments. These pipes are designed to offer superior corrosion resistance compared to standard carbon steels such as J55, K55, or N80, making them a cost-effective alternative to CRA (Corrosion Resistant Alloy) materials in moderately corrosive conditions.

Manufactured in compliance with API 5CT standards, 13Cr casing and tubing are quenched and tempered to meet mechanical performance criteria similar to T95 or C95 grades, with high yield and tensile strength, moderate hardness, and excellent resistance to sulfide stress cracking (SSC). Available in seamless form with standard or premium threaded connections, these sizes are suited for production casing and tubing strings in wells containing CO₂, chlorides, and light H₂S contamination.

The most common sizes (3-1/2", 4-1/2", 5-1/2", and 7") support a range of wellbore designs, with each available in various wall thicknesses and weights per foot.
