Copper Nickel 70/30 Reducing Tee BW Fitting ASME B16.5 Cl150 Shipbuilding Anti-Corrosion

1. Product Description

The Copper Nickel Reducing Tee is a precision-engineered pipe fitting manufactured from CuNi alloy, available in 90/10 (UNS C70600) and 70/30 (UNS C71500) material grades. This three-way fitting features a main run connection at full nominal diameter and two branch outlets of smaller dimensions, providing both flow diversion and diameter transition in a single component without the need for additional reducing adapters.

Manufactured through hot forging or seamless extrusion processes, the fitting offers a homogeneous grain structure and complete freedom from body welds. End finishes include butt weld ends with standard bevel preparation, socket weld ends with square-cut chamfered terminations, and threaded ends with precision-formed NPT or BSP threads. A post-manufacturing pickling and passivation cycle ensures a metallurgically clean surface, free from scale and surface impurities.

2.Product Applications

• Shipping industry – cargo vessels, tankers, bulk carriers, and passenger ships for engine seawater cooling, deck fire protection, ballast water handling, and accommodation service lines.

• Offshore infrastructure – fixed and floating production platforms for seawater lift, heat exchange cooling circuits, and platform firewater distribution rings.

• Media compatibility: Natural seawater, brackish water, fresh potable water, industrial cooling water, low-pressure steam, plant air, and hydrocarbon fluids.

• Water desalination – both thermal (MSF/MED) and membrane (RO) desalination plants for feed intake, brine concentration discharge, and permeate collection pipework.

• Power plants – conventional thermal, gas turbine combined-cycle, and nuclear facilities for main condenser cooling and station auxiliary water services.

• Process industries – chemical manufacturing, petroleum refining, food processing, and pharmaceutical plants for cooling water, process fluid, and utility distribution piping.

3. Product advantages:

Unmatched corrosion durability – CuNi alloys demonstrate a seawater corrosion rate below 0.025mm per year, substantially outperforming carbon steel, galvanized steel, and standard 300-series stainless steels. The alloy's passive film is self-healing, maintaining protection even after mechanical damage.

Natural bio-resistance – the controlled release of copper ions creates a micro-environment that deters attachment and growth of barnacles, mussels, and algal species. This property significantly reduces flow efficiency losses caused by biofouling accumulation.

Superior erosion resistance – the alloy withstands continuous seawater flow velocities up to 5 m/s without erosion or cavitation damage, making it particularly suited to high-flow pump discharge and circulation system applications.

Field-proven welding – CuNi alloys are readily welded using TIG and MIG processes. The material exhibits excellent resistance to hot cracking, and the required preheat is minimal (100–150°C only for sections exceeding 20mm thickness), facilitating efficient field installation.

Product traceability – each fitting is marked with heat number and supplied with a complete mill test certificate. Independent third-party inspection services are available to meet specific project specifications.

Sustainable material choice – the alloy is fully recyclable and contains no lead, cadmium, or other restricted substances, supporting environmental compliance and green building certifications.
