High-Grade Copper Nickel 90/10 Buttweld Pipe Fittings designed with ASTM B122, B171, B466, B467 Standards.

Creative Piping Solutions is a renowned manufacturer and supplier specializing in high-quality Copper Nickel 90/10 Pipe Fittings. Copper Nickel 90/10, often abbreviated as CuNi 90/10, is an alloy composed of 90% copper and 10% nickel, with small amounts of iron and manganese added to enhance its strength and resistance to corrosion. This alloy is particularly well-regarded for its excellent performance in marine environments due to its high resistance to seawater corrosion and biofouling.

Copper Nickel 90/10 pipe fittings provide a reliable and durable solution for various applications, especially in environments where corrosion resistance is paramount. Their unique properties make them an excellent choice for long-term performance in challenging conditions. CuNi 90/10 pipe fittings exhibit exceptional resistance to corrosion, particularly in seawater and brackish water environments. This makes them ideal for marine applications such as shipbuilding and offshore oil and gas platforms.

01 What is Copper Nickel 90/10?

Copper Nickel 90/10 is an alloy composed of 90% copper and 10% nickel, with small amounts of iron and manganese to enhance its strength and resistance to corrosion. This alloy is well-known for its excellent performance in marine environments.

  • Welding Methods: Common methods include TIG (GTAW), MIG (GMAW), and manual metal arc welding.
  • Filler Materials: Filler materials with similar composition to the base metal are used to ensure compatible properties.
  • Cleanliness: Ensuring a clean work environment is critical to prevent contamination.
  • Preheating and Post-weld Treatment: Usually not necessary but can depend on specific application requirements.
  • Regular Inspection: Inspect fittings regularly for signs of corrosion, wear, and damage.
  • Cleaning: Maintain cleanliness to prevent fouling and deposition.
  • Corrosion Inhibitors: Use appropriate corrosion inhibitors if needed, although typically less necessary due to the alloy's inherent resistance.
