CuNi 70/30 Equal Tee ASME B16.9 Buttweld SCH40 for Marine & Petrochemical
CuNi 70/30 Equal Tee ASME B16.9 Buttweld SCH40 for Marine & Petrochemical
1. Product Description
The Copper Nickel Equal Tee is a key fitting for perpendicular branch connections in piping systems, with all three ports of identical size. Manufactured from Cu-Ni 90/10 or 70/30 alloy by forging or seamless process, it strictly complies with ASTM B466 and ASME B16.9. Thanks to its outstanding seawater corrosion resistance, it is the preferred fitting for marine, shipbuilding, and chemical applications.
2. Product Applications
-
Shipbuilding & repair:Seawater cooling, ballast, fire fighting, sewage discharge systems
-
Offshore oil & gas platforms:Seawater lift, equipment cooling, firewater systems
-
Desalination plants:Intake, brine circulation, outfall pipelines
-
Petrochemical:Chloride-containing, saline, and weakly acidic media transmission
-
Power stations:Essential service water in nuclear plants, circulating cooling water in thermal plants
-
Others:Coastal fire facilities, large HVAC systems, marine seawater retrofit projects
3.Product Advantages
-
Outstanding seawater corrosion resistance – Forms a stable protective film in static/flowing seawater; pitting/crevice resistance far exceeds 316L stainless steel.
-
Natural anti-fouling – Continuously releases trace copper ions, effectively preventing marine organism adhesion and growth without external coatings or electrolytic systems.
-
Workability & weldability – Good ductility for cold bending/flaring; no preheat or PWHT required; weld metal matches base metal properties.
-
High flow velocity tolerance – Safe operation at seawater velocities up to 3.5 m/s, outperforming common copper alloys.
-
Life-cycle economics – Slightly higher initial cost than carbon steel but maintenance-free or very low maintenance over service life, overall cost reduced by >40%.
-
Flexible supply – Full size range; accepts non-standard angles, reducing transitions, custom orders; 3.1 certification available.
