OCTG 6.625″ 20# 25CRW 125 VAM TOP KP R3

Super Duplex 25 Chrome grades, such as 25CRW and 25CRS, are high-strength duplex stainless steels with a PREN ≥40, offering exceptional resistance to localized corrosion and H2S in high-chloride, sweet and moderately sour environments up to 450°F, making them ideal for demanding applications like tubing and liners in saltwater and water injection wells, as well as CCUS and geothermal projects where reliable performance in corrosive conditions is critical.

Field Inspection Complete!

In this first step of our PipeFacts™ quality assurance process, we send our field services team to inspect material in its stocked location. During the initial evaluation, we ensure that this material is suitable for acquisition and suitable for prime applications. Once the field inspection is complete, we move material to one of our regional storage and inspection hubs for further inspections.

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

Super Duplex 25 Chrome alloys, including 25CRW and 25CRS, are cold-hardened duplex stainless steels designed for corrosion resistance in sweet (CO2) and moderately sour (H2S) environments with high chloride concentrations, providing high strength up to 450°F.

The “Super” designation signifies a Pitting Resistance Equivalent Number (PREN) of ≥40, offering enhanced protection against H2S and localized corrosion from high chloride levels and/or oxygen, compared to standard 25 Chrome. As a result, these alloys are commonly used in tubing and liners for seawater and water injection wells. However, it is important to evaluate all relevant environmental factors, including H2S, CO2, temperature, pH, and chloride concentration, before finalizing material selection.

These alloys are classified under MR0175/ISO15156 as duplex stainless steels with a Pitting Resistance Equivalent Number (PREN) ≥40, suitable for environments with H2S partial pressures up to 3.0 psi.
