ASTM B151 Cu-Ni 90/10 Flanges
What is Cu-Ni 90/10 Flanges
Copper nickel flanges are also commonly named as cupronickel in various markets. These Cu-Ni enriched flanges are made of high quality material. The combination of these flanges includes a high amount of copper and nickel in its combination. The copper nickel 90/10 flanges are enriched with excellent properties and characteristics which are highly important for the application of the flange.
A flange is an equipment that is commonly manufactured for joining two or more pipes, valves and pumps together. The copper-nickel flanges have excellent ductility and durability. The heat and electricity insurance of these flanges is extremely high. The flanges deliver excellent ductility and strength. These pipes are applicable in the pipes which are commonly used for transferring acids, liquids and gases. Hence, the durability and ductility is a highly important feature of this grade.
