As an experienced C12200 Copper Supplier, we provide a comprehensive range of UNS C12200 Flanges designed to meet global standards and deliver consistent performance in demanding environments.
What are Copper C12200 Flanges?
Copper C12200 Flanges are pipe fittings used to connect pipes, valves, pumps, and other equipment to form a piping system. These flanges are manufactured using C12200 Alloy, which is a phosphorus-deoxidized copper containing a small amount of phosphorus to improve weldability and reduce brittleness.
This material is widely recognized for its excellent resistance to corrosion, especially in water systems, and its superior thermal and electrical conductivity.
Key Features of C12200 Alloy Flanges
The popularity of UNS C12200 Flanges comes from their unique combination of mechanical and chemical properties. Some of the standout features include:
- Excellent Corrosion Resistance: Ideal for use in water supply systems and environments exposed to moisture.
- High Thermal Conductivity: Efficient heat transfer makes it suitable for HVAC and heat exchanger systems.
- Good Weldability: Thanks to phosphorus content, C12200 Alloy is easy to weld and fabricate.
- Strong and Durable: Offers long service life even in demanding industrial applications.
- Non-Magnetic and Anti-Microbial: Useful in specialized industries like healthcare and food processing.
