Copper Nickel Ferrule Fittings

Copper nickel ferrule fittings

What are Copper Nickel Ferrule Fittings (90/10 & 70/30)?

Ferrules are nifty components in industrial piping, offering an easy-to-install option with a leak-proof seal. Copper nickel ferrule fittings use a copper-nickel composition in 90-10 or 70-30 proportions. They also contain iron and manganese. The latter is superior in strength and resilience, but its higher costs make 90-10 more in demand than copper-Ni 70/30 tube fittings.

These products work in multiple sectors, from hydraulic and pneumatic systems to nuclear plants, aerospace, pharmaceuticals, and heat exchangers. Cupro nickel 70/30 ferrules are available in different sizes per order specifications.

What are the advantages of using Copper Nickel Ferrule Fittings, particularly in applications where corrosion resistance is important?

This material has an excellent reputation for corrosion resistance, fighting acids, alkalis, salts in seawater, and ammonia. It works in the automotive and instrumentation sectors, resisting localized and general corrosion. DIN 2.0882 ferrule tube fittings also battle impingement, stress-corrosion cracking, pitting, and crevice erosion.

  • Offer durability and longer operational life
  • Cupro nickel compression fittings smoothly work in marine applications like desalination plants and seawater cooling.
  • Resist biofouling, i.e., microbial and barnacle growth
  • Handle up to 1000°F and pressure ratings up to 60,000 psi

Cupro nickel 90/10 instrumentation fittings can get produced in different shapes, like unions, nipples, and adapters. The 70-30 versions handle more seawater velocity levels.

How do advanced destructive testing methods help to assess the mechanical properties of Copper Nickel Ferrule Fittings?

Adequate quality testing of a UNS C70600 compression fitting is paramount to performance and safety assurance, particularly in demanding applications. Fatigue testing uses cyclic loading to analyses susceptibility to wear and tear.

CU NI instrumentation fittings also perform well on fracture toughness testing. This approach uses cyclic loads to test the resistance of a pre-existing crack. The results indicate the stress amount that will propagate an existing flaw.

Other destructive testing methods include tensile testing, bending, flattening, and Charpy impact tests. We clearly state all the results in the MTR to certify the application suitability of the UNS C71500 ferrule fittings.
