Marine Grade Aluminium Flanges
What Are Aluminium Flanges?
Aluminum flanges are piping components made from aluminum, used to connect pipes and equipment in various industries. They are known for their lightweight, corrosion-resistant, and weldable properties, and they offer durability and versatility in fluid handling systems. They find applications in the aerospace, automotive, pharmaceutical, food processing, and renewable energy sectors.
Aluminium flanges are key components in modern piping systems for connecting pipes, valves, pumps, and other equipment together. Made from lightweight yet sturdy aluminum metal renowned for its ease of machining processes - providing precise shaping to match various pipe diameters and configurations while decreasing production time and costs while upholding high quality standards - aluminum flanges play a pivotal role.
Aluminum flanges are an excellent choice for industrial applications due to their corrosion resistance, strength, and lightweight. However, there are drawbacks, such as the limited temperature range and high cost. Before choosing aluminium pipe flanges for your industrial needs, ensure that you understand your specific requirements, and consult with a trusted supplier to ensure that you choose the right type and size of flanges for your needs. Choosing the right flanges will guarantee your processes’ safety, reliability, and efficiency while avoiding leaks and resulting downtime.

What Types of Aluminum Flange Are Used for Marine Profiles?
Aluminium Slip on Flange: Slip-On Pipe Flanges are used to connect two pipes without the need for threading. Seals are created by welding. Slip On flanges are versatile and easy to install. The Slip-On connection means there is no stop where the pipe meets the flange body, allowing the flange to pass fully over the pipe. They are critical components in Plumbing, Marine, and Industrial piping systems. This 2 in. Imported Raised Face Flange is made from Aluminum 5086. It has a pressure rating of Class 150 with a Slip On connection.
Aluminium Flat Face Flange: Flat face (FF) flanges are similar to raised face flanges, but they have a flat surface. These flanges have a gasket surface in the same plane as the bolting circle face. The flat face is the simplest type of flange face available.Flat face flanges are easy to align during installation and are typically a more affordable option compaired to the other two flange types. The easiest way to protect these from damage and corrosion are by applying an adhesive or magnetic flange protector.
Aluminium Raised Face Flange:Raised face flange are the most common types of flanges and are used in a wide variety of industries. These flanges this get their name because the flange face is raised off the bolting circle plane. The raised face acts as a sealing surface when the flanges are bolted to another flange or piece of equipment. These flanges are available in 150# - 2500# pressure classes and are normally used in process plant applications.
