Coupling 5″ 18.0# G3-110 VAM TOP SC

The 5″ 18.0# G3-110 VAM TOP SC coupling is manufactured from Alloy G3 (UNS N06985), a high-performance nickel-based alloy engineered for severe sour service and high-chloride environments up to 400°F. With a 110 ksi minimum yield strength and exceptional resistance to H₂S, chlorides, and dissolved oxygen, this coupling is ideal for HPHT wells, AGI service, and extreme downhole conditions. Classified as a type 4d alloy under MR0175/ISO15156, G3 enables safe operation under some of the harshest sour service limits in the industry.

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 G3 (UNS N06985) is a cold-hardened nickel-based alloy designed for corrosion resistance in highly sour (H2S) environments with high chloride levels, offering high strength up to 400°F.

With its elevated nickel and molybdenum content, G3 extends the sour service capabilities of nickel alloys, while also delivering exceptional resistance to chlorides and dissolved oxygen. As a result, it is frequently used in downhole tubular components, packers, and other subsurface equipment for severely sour wells operating under high-pressure, high-temperature (HPHT) conditions, saltwater injection wells, and Acid Gas Injection (AGI) wells. However, it is essential to evaluate all environmental factors, including H2S, CO2, temperature, pH, and chloride concentration, before finalizing material selection.

For sour service conditions, G3 is classified as a type 4d alloy in MR0175/ISO15156, with no restrictions on H2S partial pressure below 300°F and capable of withstanding 300 psi H2S at 425°F.
