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.

Nickel Alloy

Corrosion Resistance Level

Extreme

Description

CRA 2550E (UNS N06255) is a premium melted, cold worked nickel-based alloy meeting the severe challenges of wells containing high chlorides, H2S and temperature. With a typical Pitting Resistance Equivalent Number of 52, it is highly resistant to pitting corrosion and chloride-induced stress corrosion cracking. For sour service applications, it is classified in MR0175/ISO15156 as a type 4d alloy, with no restrictions to partial pressure of H2S below 300°F and resistant to 300 psi H2S at 425°F. CRA 2550E-140 C-rings tested at 100% AYS in 15.5 ppg ZnBr2/CaBr2/CaCl2 brine exhibited no evidence of cracking. Tests were performed under three conditions: • 1.5 psi H2S / 500 psi CO2 / 350°F • O2 saturated / 425°F • 500 psi CO2 / 425°F CRA 2550E has excellent hydrogen embrittlement resistance at all standard strength levels.

The PipeSearch Platform consolidates update-to-date mill schedules, lead times, and global market inventory into the largest database of corrosion-resistant alloy tubulars in the world.

PipeFacts by PipeSearch is a multi-stage process that utilizes proprietary software to manage a sequence of QA/QC steps in the evaluation of OCTG. It is designed to bring transparency, integrity, and consistency to the evaluation of tubulars no matter the location of the pipe.
PipeFacts goes beyond standard physical inspections of material. It evaluates the specification of the original MTRs against API 5CRA or 5CT, identifies any exceptions, and sets a standard by which MTRs are reviewed and by which inspections are performed. Our PipeFacts process has been developed to give customers complete confidence in the product they are receiving.
