Copper Nickel Flange

Copper Nickel Flange

We are leading ASTM B171 UNS C70600 WNRF Flange Manufacturer in India, Check latest Price list of 90/10 Cuni Blind Flange

A flange is a device that connects different piping equipment as it relieves stress and provides support during vigorous movement of the flow. The Cuni Flange has a higher content of copper than other constituting alloys. These flanges have moderate corrosion resistance properties in different systems. Copper Nickel 70/30 Flanges are common types of flanges that have 70% copper and 30% nickel content with small additions of iron and manganese. These flanges have superior strength and are more suited for sea-water applications. The Copper Nickel 90/10 Flanges have enhanced ductility and toughness. These flanges are popular for use in architectural and industrial applications. A C70600 Flange has a density of 8.94 g/cm3 and possesses a shear modulus of 52Gpa while showcasing an elastic modulus of 117Gpa. The C71500 Flange is insensitive to stress corrosion and has good creep resistance at higher temperature setups in different environments. ASTM B171 UNS C70600 grade is recommended for use in pressure vessels, heat exchangers, turbines, condensers, etc. Our company is a Copper Nickel Flange manufacturer that has some of the best technicians who make us of the best practices to produce some of the best flanges in the industry.

Copper Nickel Pipe Flanges have a protruded rim that helps in connecting different piping equipment. These flanges allow room for cleaning and inspection. They are available in different flanges types as per customer requirements. The Copper Nickel Slip On Flange is essentially a ring that is placed on the pipe and welded using one or more fillet welds. The versatile flanges have a low installation cost and are easy to install and align. A Copper Nickel Blind Flange doesn’t have a face or boring center. These flanges act as blanks that terminate the flow of media in the system. These flanges have higher strength in comparison to other flange types. The institution is a Copper Nickel Flange supplier that has a vast inventory of products and possesses good contacts with different logistical chains, allowing us to deliver products to your doorsteps on short notice.
