UNIONS

COPPER NICKEL UNIONS forged fittings

Copper-nickel Unions by Nexus Alloys and Steels are a type of forged fitting widely used in various industries due to their excellent properties. The copper component provides excellent thermal conductivity and corrosion resistance, while the nickel component adds strength and durability. This makes copper-nickel Unions ideal for applications that require high strength and resistance to corrosion, such as in the marine, oil & gas, and chemical industries

union

DESCRIPTION

A union is a type of fitting that allows two pipes to be joined together in a manner that facilitates easy disconnection and reconnection without the need for cutting. Forged fittings, including Unions, are manufactured using a forging process that involves heating a piece of metal, then hammering or pressing it into the desired shape. This process increases the strength and reliability of the fitting

Key Features of Copper-Nickel Union

  • Material : They are made from a copper-nickel alloy, which provides excellent resistance to corrosion, especially in marine environments
  • Durability : The forging process used to manufacture these Unions ensures high durability and the ability to withstand extreme pressures and temperatures
  • Versatility : CuNi Unions are used in a variety of industries, including shipbuilding, desalination plants, and offshore oil and gas platforms
  • Sizes and Configurations : These Unions are available in a range of sizes and configurations to meet different piping requirements
  • Performance : They offer superior performance in challenging conditions, making them an ideal choice for industries seeking efficient and long-lasting piping solutions

GRADES

  • Copper Nickel 90/10 (C70600) : This grade contains 90% copper and 10% nickel along with small amounts of iron and manganese to improve corrosion resistance
  • Copper Nickel 70/30 (C71500) : This grade contains 70% copper and 30% nickel along with small amounts of iron and manganese. It offers even better resistance to corrosion and is used in more demanding applications

TECHNICAL SPECIFICATION
