70/30 Copper Nickel Equal Tee Forged Socket Weld ASME B16.11 Class 300 High Pressure​

1. Product Description

The Copper Nickel Equal Tee is a fitting used for equal-diameter perpendicular branch connections in piping systems, with all three ports having identical inside diameters. Manufactured from copper-nickel alloy (Cu-Ni 90/10 or 70/30) by integral forging or seamless tube hydroforming. Conforming to ASTM B466, ASME B16.9, and EN 10253-2, it offers excellent resistance to seawater corrosion, cavitation, and biofouling, widely used in shipbuilding, offshore engineering, power generation, and chemical industries.

2. Product Applications

• Merchant & naval vessels:Seawater cooling main branches, ballast water treatment system lines, fire hose branch lines, bilge collection pipes

• Offshore equipment:Jack-up platform leg cooling water pipes, FPSO seawater lift manifolds, semi-submersible platform firewater ring mains

• Desalination plants:Brine circulation pipes in multi-effect distillation units, RO membrane housing feed branches, concentrate outfall lines

• Chemical & refinery plants:Sour water lines, circulating cooling water bypasses, seawater heat exchanger inlet/outlet pipes

• Nuclear & thermal power plants:Essential service water systems, condenser circulating water inlet/outlet branches, auxiliary cooling water pipes

• Coastal facilities:Seawater source heat pump systems, coastal fire protection systems, marine monitoring station piping

3.Installation & Precautions

• Incoming inspection:Spot-check dimensions, wall thickness, and material spectrum per batch; visually inspect for cracks, folds, or lamination.

• Pre-weld preparation:Grind bevel and 25mm area on inner/outer sides to bright metal using stainless steel brush or wheel; do not use carbon steel brushes.

• Welding process:GTAW root pass, SMAW fill and cap. Use ERCuNi filler; preheat not required; interpass temperature 100-150℃.

• Fit-up requirements:Internal misalignment ≤1mm; root gap 2-3mm.

• Threaded connection:Use PTFE tape; ensure tape does not enter pipe interior. Apply standard torque values.

• Purging & pressure test:Purge after installation, then hydrotest with clean water at 1.5× design pressure for 30 minutes.

• Routine maintenance:Regularly inspect welds and connections for leakage; drain and dry piping during prolonged shutdown.
