C71500 Copper Nickel Equal Tee 70/30 Socket Weld ASME B16.11 Class 150
C71500 Copper Nickel Equal Tee 70/30 Socket Weld ASME B16.11 Class 150
1. Product Description
The Copper Nickel Equal Tee is a fitting for perpendicular branch connections from main pipelines, with all three ports of equal diameter. Manufactured from copper-nickel alloy (90/10 or 70/30) by seamless or welded processes, it complies with ASME B16.9 and ASTM B466. The product offers exceptional seawater corrosion resistance, making it an ideal choice for harsh marine environments.
2. Product Applications
-
Ship systems:Seawater cooling circuits, ballast water distribution, fire mains, bilge discharge
-
Offshore platforms:Seawater lift lines, process cooling distribution, emergency firewater loops
-
Desalination:Intake header piping, RO feed branches, concentrate discharge
-
Chemical industry:Saline wastewater, dilute acid solutions, organic solvent transmission
-
Power facilities:Component cooling water in nuclear plants, open-cycle circulating water in thermal plants
-
General engineering:Coastal building fire protection, shipyard/quay water supply, aquarium life support systems
3. Product Advantages
-
Corrosion leadership – Stable passive film in chloride media; pitting resistance >3× that of 316L stainless steel.
-
Anti-fouling – No extra coating or electrolytic devices needed; natural copper ion release inhibits marine growth.
-
Weld without heat treatment – Welding at room temperature, no hydrogen-induced cracking risk; ready for service post-weld.
-
Impact & fatigue resistant – Elongation ≥30%, high low-temperature impact energy, suitable for floating offshore facilities.
-
Wide velocity range – Recommended 0.5~3.5 m/s for seawater, up to 4.5 m/s locally acceptable.
-
Cost-effective – Much lower cost than titanium; lower maintenance cost than super duplex stainless steel.
-
Fast supply – Common sizes in stock; custom sizes with minimum 25 days lead time.
