What Is ASTM B171 C70600 Thread Flange?
Copper Nickel Threaded Flanges (UNS C70600) are designed for threaded pipe connections without welding, making them ideal for low-pressure applications and systems requiring frequent disassembly. With excellent resistance to saltwater corrosion, biofouling, and erosion, these flanges are a reliable choice for harsh marine environments.
A threaded flange (also called a screwed flange) is a type of flange that has internal threads (usually NPT or BSPT), allowing it to be screwed onto a pipe without welding.
ASTM B171 C70600 refers to Copper-Nickel 90/10 (CuNi), an alloy composed of approximately 90% copper and 10% nickel, with excellent resistance to seawater corrosion, biofouling, and erosion. It is commonly used in marine and saltwater piping systems.
ASTM B171 This specification establishes the requirements for copper-alloy plate, sheet, and circles cut from plate and sheet for pressure vessels, condensers, and heat exchangers.
