UNS C71500 CuNi 70/30 Copper Nickel Tee High Flow Erosion Resistant Pipe Fitting ASME B16.5

UNS C71500 CuNi 70/30 Copper Nickel Tee High Flow Erosion Resistant Pipe Fitting ASME B16.5

1. Product Description

Copper Nickel Tee is a T-shaped pipe fitting made of copper-nickel alloy, used for flow diversion, combining, or 90° branch connection in piping systems. By structure, it includes equal tee and reducing tee. By process, it includes seamless hot-pushed tee, die-forged tee, and welded tee. By connection, it includes butt weld, socket weld, and threaded tee. Common materials are C70600 (90/10 CuNi) and C71500 (70/30 CuNi), offering excellent seawater corrosion resistance and anti-biofouling performance.

2. Applications

• Seawater cooling systems, fire main systems, ballast water systems, and bilge drainage systems on ships;

• Seawater transport and cooling pipelines on offshore platforms, FPSOs, and offshore drilling units;

• Cooling water systems for desalination plants and coastal power plants;

• Corrosive media transportation pipelines in petrochemical plants;

• Heat exchangers, condensers, coolers, and piping distribution systems;

• Pharmaceutical, food, metallurgical, and other industries requiring high corrosion resistance and cleanliness.

3. Advantages

• Strong seawater corrosion resistance, suitable for flowing seawater;

• Resistant to pitting, crevice corrosion, and stress corrosion cracking;

• Slow release of copper ions inhibits marine biofouling;

• Good weldability, suitable for TIG, MIG, and arc welding;

• Good strength and toughness, long service life;

• Non-magnetic, suitable for magnetically sensitive equipment;

• ABS, DNV, CCS, LR, and other classification society certification available;

• Custom sizes, special wall thicknesses, and non-standard machining supported.

4. Functions

• Divides one fluid flow into two paths, or combines two flows into one;

• Provides 90° branch connection and direction change;

• Reducing tee enables pipe diameter transition while dividing or combining flow;

• Acts as a pressure-bearing connection component, ensuring connection strength and sealing reliability;

• Suitable for long-term operation under high pressure, high temperature, corrosive media, and marine environments.
