OCTG 7″ 29# 825-110 Plain End R3

This 7″ 29# 825-110 Plain End R3 casing is made from Alloy 825 (UNS N08825), a cold-hardened nickel-based alloy designed for high-strength performance in highly sour (H₂S) environments with moderate chloride levels, and rated for temperatures up to 350°F. As a Type 4c alloy under MR0175/ISO15156, it offers exceptional resistance to H₂S-related corrosion and is qualified for use in HPHT, acid gas injection (AGI), and other demanding downhole applications. Its superior sour service capability makes it a reliable choice where stainless steels are not sufficient.

During this phase of PipeFacts™, material is received into one of our regional storage and inspection hubs, and we put material through a more detailed inspection. Our teams of inspectors inspects the pipe body for traceability and potential body defects and inspects the threads while a quality team in the office evaluates the as produced specification of the material test reports (MTRs).

Disclaimer: The burst and collapse figures displayed are based on the API dimension tolerance of 87.5% of nominal wall thickness. Note that martensitic, duplex, super duplex, and nickel alloys often have tighter dimensional tolerances, therefore, increased strength ratings. The properties do not factor connection performance ratings. If your application requires more information ratings, please contact our technical services team, and we happily assist you.

Alloy Description

Alloy 825 (UNS N08825), also known as 2242, is a cold-hardened nickel-based alloy designed for corrosion resistance in highly sour (H2S) environments with moderate chloride levels, offering high strength up to 350°F.

Alloy 825 provides superior resistance to H2S compared to stainless steels, making it suitable for applications such as downhole tubular components, packers, and other subsurface equipment in sour wells under high-pressure, high-temperature (HPHT) conditions, as well as in Acid Gas Injection (AGI) wells. However, it is important to consider all environmental factors, including H2S, CO2, temperature, pH, and chloride concentration, before finalizing material selection.

This alloy is classified as a type 4c alloy in MR0175/ISO15156, with no restrictions for H2S partial pressure below 270°F and resistance to 200 psi H2S at 350°F.
