Alloy 2535 (UNS N08535) is a cold hardened nickel-based alloy intended for corrosion resistance in highly sour (H2S) environments with moderate chloride content, requiring high strength up to 350°F. 2535 offers increased resistance to the effects of H2S relative to stainless steels allowing its use as downhole tubular components, packers, and other subsurface equipment in sour wells with high-pressure and high-temperature (HPHT) conditions and Injection wells. However, all environmental factors, including H2S, CO2 , temperature, pH, and chloride concentration, should be considered before final material selection. VAM TOP® is recognized as setting the standard in reliability and performance in threaded and coupled premium connections. With a track record of over 30 years, the connection minimizes the risks that result from the most severe combined loads making it a suitable solution for even the most critical applications.
