Marine aluminum flanges are made from 5xxx series (such as 5083 and 5086) or 6xxx series (such as 6061) aluminum alloys, and are connection components specifically designed for aluminum alloy piping systems used in ships and offshore engineering.

C70600 CuNi 90/10 copper-nickel alloy offers excellent seawater corrosion resistance and erosion-corrosion resistance. The welding neck flange is butt-welded to the pipe, creating a reliable and durable connection for marine and seawater piping systems.

6061 aluminum flat slip-on flange with a flat sealing face ensures uniform gasket pressure, suitable for use with aluminum pipes or other lightweight piping, and is applied in marine piping systems.
