ASTM B446 UNS C70600 / Cu90Ni10 Copper Nickel Alloy Steel Tee ,
Buttweld Pipe Fittings
A Tee is a pipe fitting shaped like a "T" that allows fluid flow in
three directions. The C70600 Tee is manufactured from ASTM
B466-compliant material, designed for systems requiring
seawater/corrosion resistance. Standards for Fittings: While ASTM
B466 covers the base material, the tee itself is typically
manufactured to dimensional standards like: ASME B16.9 (butt-weld
fittings) ; ASME B16.11 (forged socket weld/threaded fittings).
ASTM B466 C70600 TEE fittings are the go-to choice for harsh,
chloride-rich environments where corrosion resistance, durability,
and cost-effectiveness are priorities. Clients in marine, power,
and chemical industries favor it over alternatives when seeking a
balance between performance and budget, especially for
infrastructure meant to last decades with minimal upkeep.

Clients prioritize C70600 in projects requiring long-term
reliability in corrosive environments, especially when balancing
cost and performance. Key scenarios include:
1. Marine & Offshore Applications
Shipbuilding: Cooling systems, firefighting pipelines, ballast
systems (resists biofouling and seawater corrosion).
Offshore Oil/Gas: Seawater injection systems, heat exchangers.
Desalination Plants: Brine heaters, condenser tubing (resists
chloride-ion attack).
2. Coastal Infrastructure
Power Plants: Condensers, cooling water systems (handles brackish water and
sand erosion).
Harbor Facilities: Piping for docks, sewage outfalls (resists
corrosion in tidal zones).
3. Chemical Processing
Non-Acidic Corrosive Fluids: Alkaline or neutral solutions,
hydrocarbons, and mild acids (e.g., acetic acid).
4. Budget-Conscious Projects
Clients opt for C70600 over titanium or super duplex stainless
steel when cost matters but corrosion resistance is critical.
5. Sustainability-Driven Projects
Recyclable material with low environmental impact (compliance with
green building standards like LEED).
6. Low-Maintenance Requirements
Ideal for systems where access for repairs is difficult (e.g.,
subsea pipelines, buried coastal infrastructure).
