Copper nickel buttweld fittings are essential components in piping systems where corrosion resistance and durability are paramount. These fittings are primarily crafted from Cu-Ni alloys, notably Copper Nickel 90/10 (C70600) and Copper Nickel 70/30 (C71500). The former comprises 90% copper and 10% nickel, offering commendable resistance to marine environments, while the latter, with 70% copper and 30% nickel, provides enhanced strength and superior corrosion resistance in seawater applications.

cupro nickel buttweld fittings adhere to rigorous international standards such as ASTM B122 for seamless fittings and ASTM B467 for welded counterparts. They are available in a variety of configurations, including elbows, tees, reducers, caps, stub ends, and crosses. These fittings typically span sizes ranging from 1/2" to 24" (DN 15 to DN 600) with wall thicknesses classified under Schedule 10S, 40S, 80S, and higher as per specific operational requirements.

Designed to endure varying pressure ratings, copper nickel buttweld fittings are versatile for both high and low-pressure applications across industries. Their usage is prevalent in marine sectors for shipbuilding, offshore platforms, and seawater desalination plants. Additionally, they find application in petrochemical environments such as oil refineries and chemical processing facilities, as well as in power generation settings including thermal and nuclear power plants.

The advantages of copper nickel buttweld fittings lie in their exceptional resistance to corrosion in aggressive seawater and brine conditions, ensuring prolonged service life and minimal maintenance. Their robust mechanical properties further underscore their suitability for diverse industrial processes demanding reliable performance and longevity in harsh operating environments.
