  • N80l80 Seamless Pipe Super 13cr - China

    price: 11.00 Dollar US$

    Oil Casing: What are 13Cr Pipe and Super 13Cr Material? 13Cr Oil Casing 114.3mm Oil casing is an essential equipment in oil and gas extraction.

    It not only provides structural support for oil wells but also protects the wellbore from corrosion and collapse.

    Among various materials, 13Cr pipe and Super 13Cr material are highly regarded for their excellent performance.

    13Cr pipe is a high-chromium alloy steel with a chromium content of approximately 13%.

    This material endows the casing with outstanding corrosion resistance, particularly in acidic environments containing carbon dioxide (CO₂) and hydrogen sulfide (H₂S).

    The addition of chromium enhances the passivation ability of the steel, forming a dense chromium oxide film that effectively blocks the invasion of corrosive media.

    Additionally, 13Cr pipe possesses high strength and toughness, allowing it to withstand complex downhole conditions.
