Aluminum weld neck flanges are manufactured from aluminum alloys such as 5083, 6061, and 5086, offering lightweight characteristics, high strength, and excellent resistance to marine corrosion.

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.

As a core component of marine piping systems that bears pressure, connects, and seals, flange joints are made of 5086 marine aluminum alloy.

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.

5083 aluminum alloy flanges in O temper feature excellent corrosion resistance, lightweight properties, and superior weldability. They comply with ASME, EN, and GB standards and are suitable for marine applications.

5083, 5086, and 6061 aluminum flanges feature lightweight construction, excellent thermal conductivity, and outstanding corrosion resistance, and are certified by major classification societies such as DNV-GL, ABS, LR, and CCS.

5083 aluminum threaded flanges are specifically designed for marine piping systems, offering excellent corrosion resistance, lightweight construction, and reliable sealing, along with easy installation and maintenance.
