ASTM B466 Copper Nickel Equal Tee C71500 Seamless Socket Weld 150LB for Ship
ASTM B466 Copper Nickel Equal Tee C71500 Seamless Socket Weld 150LB for Ship
1. Product Description
The Copper Nickel Equal Tee is a branch fitting with all three ports having identical inside diameters, manufactured from Cu-Ni 90/10 or Cu-Ni 70/30 alloy by seamless drawing or welded forming. Strictly conforming to ASTM B466, ASME B16.9, and MSS SP-43, it offers exceptional seawater corrosion resistance and anti-fouling properties, widely used in offshore engineering, marine piping, and chemical pipeline systems.
2. Product Applications
-
Ocean-going vessels:Main/auxiliary engine seawater cooling, ballast water systems, fire main lines, sewage treatment unit piping
-
Floating offshore facilities:Semi-submersible platform seawater risers, FPSO process cooling water manifolds, deep-sea production equipment cooling branch lines
-
Seawater utilization:Once-through seawater cooling in power plants, essential service water in coastal nuclear plants, seawater flushing pipelines
-
Chemical sector:Evaporator brine circulation, chloride solution transmission, fertilizer plant saline wastewater lines
-
Shipbuilding & repair:Dock seawater lines, ballast water treatment system retrofits
-
Others:Marine research facilities, subsea observatory cooling systems, seawater aquaculture farm piping
3.Installation & Precautions
-
Unpacking & storage:Inspect for dents or deformation after unpacking; store on raised platforms to avoid moisture; do not store with sulfides or acids.
-
End cleaning:Wipe ends with clean cloth dipped in industrial alcohol to remove rust preventive oil and dust before welding or connection.
-
Butt weld key points:Bevel angle ≤35°; align inner walls flush during fit-up. Use low current, fast welding; remove slag after each pass.
-
Socket weld:Gap between pipe and socket not too large; at least two passes around circumference; ensure uniform fillet height.
-
Threaded connection:Use PTFE tape or thread sealant; keep concentric during tightening to avoid thread damage.
-
System pressure test:Use fresh water for hydrotest; pressurize slowly to 1.5× working pressure; hold for 30 minutes.
-
Prohibitions:
-
Do not use for strong oxidizing acids (e.g., conc. nitric acid) or media with high ammonia content.
-
Do not strike the fitting directly with a steel hammer during installation.
-
Provide adequate pipe supports to prevent excessive bending loads on the tee.
