Copper Nickel Long Radius Elbow DIN 86090
DIN 86090 covers a range of sizes, from small-diameter pipes for cooling and lubrication systems to larger-diameter pipes for seawater supply and fire-fighting systems. The standard also specifies the markings that must be applied to the pipes and tubes to indicate their size, material, and manufacturer.
Overall, DIN 86090 provides a framework for the production and testing of high-quality copper-nickel pipes and tubes that are suitable for use in harsh marine environments, such as offshore oil and gas platforms, ships, and coastal infrastructure.
