Minimum Ultimate Tensile Strength
Internal / Burst Pressure
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.
Corrosion Resistance Level
28 Chrome is typically supplied as a cold-worked solid solution nickel-based alloy, capable of meeting the severe challenges of high temperature, high pressure, sour wells. The alloy is classified in MR0175/ISO15156 as a type 4c alloy, with no restrictions to partial pressure of H2S below 270F and resistant to 100 psi H2S at 425°F.

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.
