View Cupro Nickel 90/10 Slip on Flanges Sizes & Weigh Chart, 70/30 Copper Blind Flange Manufacturer in India

Copper-nickel or cupronickel, is made up of manganese, iron, and nickel. These Copper Nickel Pipe Flanges are highly resistant to corrosion and resist deformation under extreme temperatures. Along with this general strength, these flanges also possess a good amount of fatigue strength. These flanges are mostly seen in use in marine applications due to their resistance to seawater. It is also used in a lot of offshore industries due to its durability and distinct properties. We are one of the top Copper Nickel Flanges manufacturers in India who focus on creating high-quality products at the most reasonable prices.

High Pressure Copper Nickel Threaded Flange Supplier, Check Weight Chart of 70/30 copper nickel Weld Neck Flanges

90/10 flanges contain 90% of copper and 10% of nickel. The Cupro Nickel 90/10 Slip on Flanges is a popular flange because of its costs as well as its applications. It can be easily slid on pipes and attached via welding. These flanges are available either as raised face flanges or flat face slip-on flanges. The 90/10 cuni Socket Weld Flanges is suitable for low pressure and temperature scenarios. Here the pipe is fitted in the socket end, and a fillet weld is applied to fix the connection. All our products can be customized into different shapes and sizes as per your requirements.

The 70/30 Copper Blind Flange is made up of 30% nickel and the rest is made from chromium. This flange is stronger as compared to the 90/10 flanges and is used to block or isolate pipelines in a piping system. Copper Nickel Threaded Flange is also referred to as companion flanges and is common when reducing connections. Our fantastic workers use the best raw materials and cutting-edge technology to produce the best flanges. Want to know more about our products contact us.
